<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The prospectus and this prospectus supplement, including the documents incorporated by reference into the prospectus and this
prospectus supplement, contain both historical and forward-looking statements within the meaning of Section&nbsp;27A of the U.S.&nbsp;Securities Act of 1933, as amended
(the&nbsp;"U.S.&nbsp;Securities Act"), and Section&nbsp;21E of the U.S.&nbsp;Securities Exchange Act of 1934, as amended (the&nbsp;"U.S.&nbsp;Exchange Act"), and forward-looking
information within the meaning of Canadian securities laws (collectively, "forward-looking statements"). This information has been included to provide readers with information about the Corporation
and its subsidiaries and affiliates, including management's assessment of the Corporation's and its subsidiaries' future plans and operations. This information may not be appropriate for other
purposes. Forward-looking statements are typically identified by words such as "anticipate", "expect", "project", "estimate", "forecast", "plan", "intend", "target", "believe", "likely" and similar
words suggesting future outcomes or statements regarding an outlook. Forward-looking information or statements included or incorporated by reference in the prospectus and this prospectus supplement
include, but are not limited to, statements with respect to the following: expected earnings before interest and taxes ("EBIT") or expected adjusted EBIT; expected earnings/(loss) or adjusted
earnings/(loss); expected earnings/(loss) or adjusted earnings/(loss) per share; expected available cash flow from operations ("ACFFO"); expected future cash flows; expected costs related to announced
projects and projects under construction; expected in-service dates for announced projects and projects under construction; expected capital expenditures; expected equity funding requirements for the
Corporation's commercially secured growth program; expectations about the Corporation's joint venture partners' ability to complete and finance projects under construction; expected closing of
acquisitions and dispositions; estimated cost and impact to the Corporation's overall financial performance of complying with the settlement consent decree related to Line 6B and Line 6A; estimated
future dividends; expected future actions of regulators; expected costs related to leak remediation and potential insurance recoveries; expectations regarding commodity prices; supply forecasts; this
offering, including the closing date thereof and the expected use of proceeds; the Merger Transaction (as&nbsp;defined herein) and expectations regarding the number of Common Shares
(as&nbsp;defined herein) to be issued in connection therewith and the timing, completion and impact thereof; expectations regarding the impact of the Merger Transaction; expectations regarding the
impact of the dividend payout policy and dividend payout expectation; expectations on impact of hedging program; and strategic alternatives currently being evaluated in connection with the
United&nbsp;States sponsored vehicles strategy. </FONT></P>

the Corporation believes these forward-looking statements are reasonable based on the information available on the date such statements are made and processes used to prepare

undue reliance on forward-looking statements. By their nature, these statements involve a variety of assumptions, known and unknown risks and uncertainties and other factors, which may cause
actual results, levels of activity and achievements to differ materially from those expressed or implied by such statements. Material assumptions include assumptions about the following: the expected
supply of and demand for crude oil, natural gas, natural gas liquids ("NGL") and renewable energy; prices of crude oil, natural gas, NGL and renewable energy; exchange rates; inflation;
interest rates; availability and price of labour and construction materials; operational reliability; customer and regulatory approvals; maintenance of support and regulatory approvals for the
Corporation's projects; anticipated in-service dates; weather; the timing and completion of this offering and the Merger Transaction, including receipt of regulatory and shareholder approvals and the
satisfaction of other conditions precedent, as applicable; the realization of anticipated benefits and synergies of the Merger Transaction and the timing thereof; the success of integration plans;
cost of complying with the settlement consent decree related to Line 6B and Line 6A; impact of the dividend policy on the Corporation's future cash flows; credit ratings; capital project funding;
expected earnings/(loss) or adjusted earnings/(loss); expected EBIT or expected adjusted EBIT; expected earnings/(loss) or adjusted earnings/(loss) per share; expected future cash flows and expected
future ACFFO; and estimated future dividends. Assumptions regarding the expected supply of and demand for crude oil, natural gas, NGL and renewable energy, and the prices of these commodities, are
material to and underlie all forward-looking statements. These factors are relevant to all forward-looking statements as they may impact current and future levels of demand for the Corporation's
services. Similarly, exchange rates, inflation and interest rates impact the economies and business environments in which the Corporation operates and may impact levels of demand for the Corporation's
services and cost of inputs, and are therefore inherent in all forward-looking statements. Due to the interdependencies and correlation of these macroeconomic factors, the impact of any one assumption
on a forward-looking statement cannot be determined with certainty, particularly with respect to the impact of the Merger Transaction on the Corporation; expected EBIT, adjusted EBIT, earnings(/loss),
adjusted earnings/(loss) and associated per share amounts, ACFFO or estimated future dividends. The most relevant assumptions associated with forward-looking statements on projects under construction,
including estimated completion dates and expected capital expenditures, include the following: the availability and price of labour and construction materials; the effects of inflation and foreign
exchange rates on labour and material costs; the effects of interest rates on borrowing costs; the impact of weather; and customer and regulatory approvals on construction and in-service schedules. </FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
Corporation's forward-looking statements are subject to risks and uncertainties pertaining to the impact of the Merger Transaction, operating performance, regulatory parameters,
dividend policy, project approval and support, weather, economic and competitive conditions, public opinion, changes in tax law and tax rate increases, exchange rates, interest rates, commodity prices
and supply of and demand for commodities and the settlement consent decree related to Line 6B and Line 6A, including but not limited to those risks and uncertainties discussed in the prospectus and
this prospectus supplement and in documents incorporated by reference into the prospectus and this prospectus supplement. The impact of any one risk, uncertainty or factor on a particular
forward-looking statement is not determinable with certainty as these are interdependent and the Corporation's future course of action depends on management's assessment of all information available
at the relevant time. Except to the extent required by applicable law, the Corporation assumes no obligation to publicly update or
revise any forward-looking statements made in the prospectus and this prospectus supplement or otherwise, whether as a result of new information, future events or otherwise. All subsequent
forward-looking statements, whether written or oral, attributable to the Corporation or persons acting on the Corporation's behalf, are expressly qualified in their entirety by these cautionary
statements. </FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;For
more information on forward-looking statements, the assumptions underlying them, and the risks and uncertainties affecting them, see "Special Note Regarding Forward-Looking
Statements" in the prospectus and "Risk Factors" in this prospectus supplement and the&nbsp;prospectus. </FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On September&nbsp;5, 2016, the Corporation entered into an agreement and plan of merger dated as of September&nbsp;5, 2016
(the&nbsp;"Merger Agreement") with Sand Merger Sub,&nbsp;Inc. ("Merger Sub"), a direct wholly-owned subsidiary of the Corporation, and Spectra Energy Corp ("Spectra Energy"). Pursuant to the
Merger Agreement, the Corporation and Spectra Energy agreed to combine in a share-for-share merger transaction (the&nbsp;"Merger Transaction") whereby, as soon as practicable on the closing date of
the Merger Transaction, Merger Sub will merge with and into Spectra Energy (the&nbsp;"Merger") in accordance with the provisions of the General Corporation Law of the State of Delaware. Following
the Merger, Spectra Energy will be a direct wholly-owned subsidiary of the Corporation and the separate corporate existence of Spectra Energy will continue unaffected by the Merger, except as set
forth in the Merger Agreement. At the effective time of the Merger (the&nbsp;"Effective Time"), each common share of Spectra Energy issued and outstanding immediately prior
to the Effective Time will automatically be converted into, and become exchangeable for, 0.984 of a validly issued, fully paid and non-assessable common share of the Corporation ("Common Shares").
Upon completion of the Merger Transaction, the shareholders of the Corporation are expected to own approximately 57% of the issued and outstanding Common Shares and Spectra Energy shareholders are
expected to own approximately 43% of the issued and outstanding Common&nbsp;Shares. </FONT></P>


<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
Merger Transaction is expected to close in the first quarter of 2017 subject to the receipt of both companies' shareholder approvals, along with certain regulatory and government
approvals, including compliance with the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and approval under the </FONT><FONT SIZE=2><I>Competition Act</I></FONT><FONT SIZE=2>
(Canada), and the satisfaction of other customary closing conditions. </FONT></P>

if we default on a payment of principal of, premium, if any, or interest on any such Senior Indebtedness or there shall occur an event of default under such Senior Indebtedness and we do not cure the
default within the applicable grace period, if the holders of the Senior Indebtedness have the right to accelerate the maturity of such indebtedness or if the terms of such Senior Indebtedness
otherwise restrict us from making payments to junior creditors. See "Description of the Notes&nbsp;&#151;&nbsp;Subordination." Our Senior Indebtedness as of December&nbsp;8,

There is no limit on the number of Deferral Periods that may occur. Such deferral will not constitute an event of default or any other breach under the Notes and the indenture governing

<P style="font-family:times;text-align:justify"><FONT SIZE=2><B><I> The tax treatment of the Notes for U.S.&nbsp;federal income tax purposes is&nbsp;uncertain.  </I></B></FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;There is no authority that addresses the tax treatment of an instrument, such as the Notes, that is denominated as a debt instrument
but that provides for an Automatic Conversion into Conversion Preferred Shares. It is therefore unclear whether the Notes should be treated as equity or debt of Enbridge for U.S.&nbsp;federal income
tax purposes. We believe, however, that the Notes should be treated as equity of Enbridge for U.S.&nbsp;federal income tax purposes, and the terms of the Notes require a U.S.&nbsp;holder
(as&nbsp;defined below) and Enbridge (in&nbsp;the absence of a statutory, regulatory, administrative or judicial ruling to the contrary) to treat the Notes for U.S.&nbsp;federal income tax
purposes in accordance with such characterization. However, because there is no authority that specifically addresses the tax treatment of the Notes, it is possible that the Notes could be treated as
debt of Enbridge for U.S.&nbsp;federal income tax purposes, in which case you may be subject to adverse tax consequences, as discussed in "Material Income Tax
Considerations&nbsp;&#151;&nbsp;Material United&nbsp;States Federal Income Tax Considerations&nbsp;&#151;&nbsp;Alternative Treatments." </FONT></P>

Underwriters. The price paid for each Note may bear no relationship to the price at which the Conversion Preference Shares issuable on conversion of the Notes may trade subsequent to this offering.
The Corporation cannot predict at what price the Conversion Preference Shares may trade and there can be no assurance that an active trading market will develop for the Conversion Preference Shares
or, if developed, that such market will be sustained. The Corporation is under no obligation to list the Conversion Preference Shares on any stock exchange or other&nbsp;market. </FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Holders of Conversion Preference Shares will not have a right to dividends on such shares unless declared by the Corporation's board of
directors. The declaration of dividends is in the discretion of the board of directors even if the Corporation has sufficient funds, net of its liabilities, to pay such dividends. Provisions of
various trust indentures and credit arrangements to which the Corporation is a party restrict the Corporation's ability to declare and pay dividends under certain circumstances and, if such
restrictions apply, they may, in turn, have an impact on the Corporation's ability to declare and pay dividends on the Conversion Preference Shares. In addition, the Corporation may not declare or pay
a dividend if there are reasonable grounds for believing that:
(i)&nbsp;the Corporation is, or would after the payment be, unable to pay its liabilities as they become due, or (ii)&nbsp;the realizable value of the Corporation's assets would thereby be less
than the aggregate of its liabilities and stated capital of its outstanding shares. Liabilities of the Corporation will include those arising in the course of its business, indebtedness, including
inter-company debt, and amounts, if any, that are owing by the Corporation under guarantees in respect of which a demand for payment has been made. In addition, a dividend (including a deemed
dividend) received on Conversion Preference Shares may be subject to Canadian non-resident withholding tax and, if any such dividends are so subject, no additional amounts will be payable to holders
of Conversion Preference Shares in respect of such withholding tax. See "Certain Canadian Federal Income Tax Considerations&nbsp;&#151;&nbsp;Conversion Preference

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The credit ratings applied to the Notes and the Conversion Preference Shares issuable on conversion of the Notes are an assessment by
Moody's Investors Service,&nbsp;Inc. ("Moody's"), Standard&nbsp;&amp; Poor's Ratings Services ("S&amp;P") and DBRS&nbsp;Limited ("DBRS") of the Corporation's ability to pay its obligations. The credit
ratings are based on certain assumptions about the future performance and capital structure of the Corporation that may or may not reflect the actual performance or capital structure of the
Corporation. Changes in credit ratings of the Notes and the Conversion Preference Shares issuable on conversion of the Notes may affect the market price or value and the liquidity of the Conversion
Preference Shares. There is no assurance that any credit rating assigned to the Notes or the Conversion Preference Shares will remain in effect for any given period of time or that any rating will not
be lowered or withdrawn entirely by the relevant rating agency. </FONT></P>

debt before payments may be made on the Conversion Preference Shares and other preference shares, if&nbsp;any. </FONT></P>

term EBIT, as used in this prospectus supplement, represents net earnings before interest expense and income taxes. EBIT does not have any standardized
meaning prescribed by U.S.&nbsp;GAAP and therefore may not be comparable with the calculation of similar measures for other companies. EBIT is presented, solely as a supplemental measure, because we
believe that it is frequently used by investors to evaluate a company's operating performance. We believe that EBIT, while providing useful information, should not be considered in isolation or as a
substitute for net earnings, as an indicator of operating performance or as an alternative to cash flow from operating activities as a measure of liquidity. EBIT is calculated from and reconciled to
net earnings on a consolidated and operating business segment basis as&nbsp;follows: </FONT></DD></DL>

 <P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Corporation evaluates its performance using a variety of measures. Earnings coverage discussed above is not defined under U.S.&nbsp;GAAP
and, therefore, should not be considered in isolation or as an alternative to, or more meaningful than, net earnings as determined in accordance with U.S.&nbsp;GAAP as an indicator of the
Corporation's financial performance or liquidity. This measure is not necessarily comparable to a similarly titled measure of another company. </FONT></P>

Corporation's dividend requirements on all of its preference shares, adjusted to a before tax equivalent using an effective income tax rate of 1,545% at December&nbsp;31, 2015 and
13% at September&nbsp;30, 2016, amounted to approximately negative $&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;million for the 12&nbsp;months ended December&nbsp;31, 2015 and approximately
$&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;million for the 12&nbsp;months ended September&nbsp;30, 2016. The effective income tax rate of
1,545% at December&nbsp;31, 2015 was unusually high because of the tax effect of certain permanent items that are not associated with the current year earnings, relative to the low consolidated
earnings. For comparability, if the September&nbsp;30, 2016 effective income tax rate was used instead of the 2015 effective income tax rate, the Corporation's dividend requirements for the
12&nbsp;months ended December&nbsp;31, 2015 would have been approximately $&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;million and the earnings coverage ratio would have
been&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;times the
Corporation's aggregate dividend and pro&nbsp;forma interest requirements for this period. This would result in the Corporation's earnings coverage ratio for the 12&nbsp;month period ended
December&nbsp;31, 2015 being less than one-to-one. Additional earnings before interest and income tax for the 12&nbsp;months ended December&nbsp;31, 2015 of $&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;million would
be required to achieve a one-to-one earnings coverage ratio. The Corporation's pro&nbsp;forma interest requirements for the 12&nbsp;months ended December&nbsp;31, 2015 amounted to approximately
$&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;million and for the 12&nbsp;months ended September&nbsp;30, 2016 amounted to approximately
$&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;million. The Corporation's earnings before interest and
income tax for the 12&nbsp;months ended December&nbsp;31, 2015 were approximately $&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;million, which

$&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;million, which is&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;times the Corporation's aggregate dividend and pro&nbsp;forma interest

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;So long as no event of default has occurred and is continuing, we may elect, in our sole option, at any date other than an Interest
Payment Date (a&nbsp;"Deferral Date"), to defer the interest payable on the Notes on one or more occasions for up to five consecutive years (a&nbsp;"Deferral Period"). There is no limit on the
number of Deferral Periods that may occur. Such deferral will not constitute an event of default or any other breach under the Indenture and the Notes. Deferred interest will accrue, compounding on
each subsequent Interest Payment Date, until paid. A Deferral Period terminates on any Interest Payment Date where the Corporation pays all accrued and unpaid interest on such date. No Deferral Period
may extend beyond the Maturity Date. We will give the holders of the Notes (the&nbsp;"Noteholders") written notice of our election to commence or continue a Deferral Period at least 10 and not more
than 60&nbsp;days before the next Interest Payment&nbsp;Date. </FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
Automatic Conversion shall occur upon an Automatic Conversion Event (the&nbsp;"Conversion Time"). At the Conversion Time, the Notes shall be automatically converted, without the
consent of the Noteholders, into a newly issued series of fully-paid Conversion Preference Shares. At such time, Notes shall be deemed to be immediately and automatically surrendered and cancelled
without need for further action by Noteholders, who shall thereupon automatically cease to be holders thereof and all rights of any such holder as a debtholder of the Corporation shall automatically
cease. At the Conversion Time, the Noteholders will receive one Conversion Preference Share for each US$1,000 principal amount of Notes held immediately prior to the Automatic Conversion together with
the number of Conversion Preference Shares (including fractional shares, if applicable) calculated by dividing the amount of accrued and unpaid interest, if any, on the Notes, by&nbsp;US$1,000. </FONT></P>

an Automatic Conversion of the Notes, the Corporation reserves the right not to issue some or all, as applicable, of the Conversion Preference Shares to Ineligible Persons. In such

sale of such Conversion Preference Shares through a registered dealer retained by the Corporation for the purpose of effecting the sale (to&nbsp;parties other than the Corporation, its affiliates or
other Ineligible Persons) on behalf of such Ineligible Persons. Such sales, if any, may be made at any time and any price. The Corporation will not be subject to any liability for failing to sell
Conversion Preference Shares on behalf of any such Ineligible Persons or at any particular price on any particular day. The net proceeds received by the Corporation from the sale of any such
Conversion Preference Shares will be divided among the Ineligible Persons in proportion to the number of Conversion Preference Shares that would otherwise have been delivered to them, after deducting
the costs of sale and applicable taxes, if any. The Corporation will make payment of the aggregate net proceeds to the Depositary (if&nbsp;the Notes are then held in the book-entry only system) or
to the registrar and transfer agent (in&nbsp;all other cases) for distribution to such Ineligible Persons in accordance with the procedures of the Depositary or&nbsp;otherwise. </FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Notes will be represented by fully registered global securities (the&nbsp;"Global Securities") registered in the name of
Cede&nbsp;&amp;&nbsp;Co. (the&nbsp;nominee of The Depository Trust Company (the&nbsp;"Depositary")), or such other name as may be requested by an authorized representative of the Depositary. The
authorized minimum denominations of each Note will be US$2,000 and integral multiples of US$1,000 in excess thereof. The provisions set forth under "Description of Debt
Securities&nbsp;&#151;&nbsp;Global Securities" in the accompanying prospectus will be applicable to the Notes. Accordingly, Notes may be transferred or exchanged only through
the Depositary and its participants. Except as described under "Description of Debt Securities&nbsp;&#151;&nbsp;Global Securities" in the accompanying prospectus, owners of
beneficial interests in the Global Securities will not be entitled to receive Notes in definitive form. Account holders in the Euroclear or Clearstream
clearance systems may hold beneficial interests in the Notes through the accounts that each of these systems maintains as a participant in the&nbsp;Depositary. </FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Each
person owning a beneficial interest in a Global Security must rely on the procedures of the Depositary and, if such person is not a participant, on the procedures of the participant
through which such person owns its interest in order to exercise any rights of a holder under the Indenture. The laws of some jurisdictions require that certain purchasers of securities take physical
delivery of such securities in certificated form. Such limits and such laws may impair the ability to transfer beneficial interests in a Global Security representing the&nbsp;Notes. </FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2><B><I> The Depositary  </I></B></FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The following is based on information furnished by the Depositary: The Depositary is a limited-purpose trust company organized under
the New&nbsp;York Banking Law, a "banking organization" within the meaning of the New&nbsp;York Banking Law, a member of the Federal Reserve System, a "clearing corporation" within the meaning of
the New&nbsp;York Uniform Commercial Code, and a "clearing agency" registered pursuant to the provisions of Section&nbsp;17A of the U.S.&nbsp;Securities Exchange Act. The Depositary holds
securities that its participants ("Participants") deposit with the Depositary. The Depositary also facilitates the settlement among Participants of securities transactions, such as transfers and
pledges, in deposited securities through electronic computerized book-entry changes in Participants' accounts, thereby eliminating the need for physical movement of securities certificates. These
direct Participants ("Direct Participants") include securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations. Access to the Depositary's system is
also available to others such as securities brokers and dealers, banks and trust companies that clear through or maintain a custodial relationship with a Direct Participant, either directly or
indirectly ("Indirect Participants"). The rules applicable to the Depositary and its Participants are on file with the&nbsp;SEC. </FONT></P>


<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Purchases
of the Notes under the Depositary's system must be made by or through Direct Participants, which will receive a credit for such Notes on the Depositary's records. The ownership
interest of each actual purchaser of each Note represented by a Global Security ("Beneficial Owner") is in turn to be recorded on the Direct and Indirect Participants' records. Beneficial Owners will
not receive written confirmation from the Depositary of their purchase. Beneficial Owners are, however, expected to receive written confirmations providing details of the transaction, as well as
periodic statements of their holdings, from the Direct or Indirect Participants through which such Beneficial Owner entered into the transaction. </FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2>Transfers
of ownership interests in a Global Security representing Notes are to be accomplished by entries made on the books of Participants acting on behalf of Beneficial Owners. Beneficial Owners of
a Global Security representing the Notes will not receive Notes in definitive form representing their ownership interests therein, except in the event that use of the book-entry system for such Notes
is discontinued. </FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;To
facilitate subsequent transfers, the Global Securities representing the Notes which are deposited with the Depositary are registered in the name of the Depositary's nominee,
Cede&nbsp;&amp;&nbsp;Co., or such other name as may be requested by an authorized representative of the Depositary. The deposit of Global Securities with the Depositary and their registration in the
name of Cede&nbsp;&amp;&nbsp;Co. or such other nominee effect no change in beneficial ownership. The Depositary has no knowledge of the actual Beneficial Owners of the Global Securities representing
the Notes; the Depositary's records reflect only the identity of the Direct Participants to whose accounts such Notes are credited, which may or may not be the Beneficial Owners. The Participants will
remain responsible for keeping account of their holdings on behalf of their customers. </FONT></P>


<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Conveyance
of notices and other communications by the Depositary to Direct Participants, by Direct Participants to Indirect Participants, and by Direct Participants and Indirect

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Neither
the Depositary nor Cede&nbsp;&amp;&nbsp;Co. (nor&nbsp;such other nominee of the Depositary) will consent or vote with respect to the Global Securities representing the Notes.
Under its usual procedures, the Depositary mails an "omnibus proxy" to the Corporation as soon as possible after the applicable record date. The omnibus proxy assigns Cede&nbsp;&amp;&nbsp;Co.'s
consenting or voting rights to those Direct Participants to whose accounts the Notes are credited on the applicable record date (identified in a listing attached to the omnibus&nbsp;proxy). </FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Principal,
premium, if any, and interest payments on the Global Securities representing the Notes will be made to Cede&nbsp;&amp;&nbsp;Co. (or&nbsp;such other nominee as may be
requested by an authorized representative of the Depositary). The Depositary's practice is to credit Direct Participants' accounts, upon the Depositary's receipt of funds and corresponding detail
information from the Corporation or the Trustee, on the applicable payment date in accordance with their respective holdings shown on the Depositary's records. Payments by Participants to Beneficial
Owners will be governed by standing instructions and customary practices, as is the case with securities held for the accounts of customers in bearer form or registered in "street name," and will be
the responsibility of such Participant and not of the Depositary, the Trustee or the Corporation, subject to any statutory or regulatory requirements as may be in effect from time to time. Payment of
principal, premium, if any, and interest to Cede&nbsp;&amp;&nbsp;Co. (or&nbsp;such other nominee as may be requested by an authorized representative of the Depositary) is the responsibility of the
Corporation or the Trustee, disbursement of such payments to Direct Participants
shall be the responsibility of the Depositary, and disbursement of such payments to the Beneficial Owners shall be the responsibility of Direct and Indirect Participants. </FONT></P>


<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
Depositary may discontinue providing its services as securities depository with respect to the Notes at any time by giving reasonable notice to the Corporation or the Trustee. Under
such circumstances, in the event that a successor securities depository is not obtained, Notes in definitive form are required to be printed and delivered to each Noteholder. </FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Settlement
for the Notes will be made in immediately available funds. Secondary market trading in the Notes will be settled in immediately available funds. </FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2><B> Certain Provisions of the Preference Shares as a Class  </B></FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Corporation is authorized to issue an unlimited number of preference shares without nominal or par value, issuable in series and,
with respect to each series, the board of directors of the Corporation shall fix the number of shares comprising the series and determine the designation, rights, privileges, restrictions and
conditions attaching to the shares of the series, subject to certain limitations. </FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The

priority on the return of capital or any other distribution of assets of the Corporation in the event of the liquidation, dissolution or winding-up of the Corporation, whether voluntary or involuntary
(a&nbsp;"liquidation distribution"). </FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
preference shares of each series shall be entitled to preferences over the Common Shares and any other shares of the Corporation (together, the "junior shares") that may rank junior
to the preference shares with respect to priority in the payment of dividends and with respect to priority on a liquidation distribution. Subject to certain limitations, the board of directors of the
Corporation may give the preference shares of any series such other preferences over the junior shares as the board of directors of the Corporation sees&nbsp;fit. </FONT></P>

of any such meeting, the quorum therefor and the conduct thereof shall </FONT><FONT SIZE=2><I>mutatis mutandis</I></FONT><FONT SIZE=2> be those then prescribed by the Corporation's by-laws or

and should not be construed to be, legal or tax advice to any particular holder and no representation is made with respect to the United&nbsp;States federal tax consequences or Canadian tax

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;This section describes the material United&nbsp;States federal income tax consequences of owning and disposing of the Notes we are
offering. It applies only to holders who acquire Notes in the offering at the offering price and who hold their Notes as capital assets for United&nbsp;States federal income tax purposes. This
section does not apply to members of a class of holders subject to special rules, such as a dealer in securities, a trader in securities that elects to use a mark-to-market method of accounting, a
bank, a life insurance company, a tax-exempt organization, a person that actually or constructively owns 10% or more of our voting stock, a person that owns Notes that are a hedge or that are hedged
against interest rate risks, a person that owns Notes as part of a straddle or conversion transaction for United&nbsp;States federal income tax purposes, a person that purchases or sells Notes as
part of a wash sale for United&nbsp;States federal income tax purposes, or a U.S.&nbsp;holder (as&nbsp;defined below) whose functional currency for tax purposes is not the United&nbsp;States
dollar. This section is based on the Internal Revenue Code of 1986, as amended (the&nbsp;"Code"), its legislative history, existing and proposed regulations under the Code, published rulings and
court decisions, all as currently in effect. These laws are subject to change, possibly on a retroactive basis. </FONT></P>

section applies only to U.S.&nbsp;holders. A U.S.&nbsp;holder is a beneficial owner of a Note who is a citizen or resident of the United&nbsp;States, a domestic corporation,
an estate whose income is subject to United&nbsp;States federal income tax regardless of its source, or a trust if a United&nbsp;States court can exercise primary supervision over the trust's

Notes should be treated as equity or debt of Enbridge for U.S.&nbsp;federal income tax purposes. Enbridge believes, however, that the Notes should be treated as equity of Enbridge for
U.S.&nbsp;federal income tax purposes, and the terms of the Notes require a holder (in&nbsp;the absence of a statutory, regulatory, administrative or judicial ruling to the contrary) to treat the
Notes for U.S.&nbsp;federal income tax purposes in accordance with such characterization. Except as discussed under "&#151;&nbsp;Alternative </FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2><I> Payments of Interest  </I></FONT></P>

</UL>

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In general, the interest payments to U.S.&nbsp;holders with respect to the Notes will be treated as dividends to the extent of
Enbridge's current or accumulated earnings and profits as determined for U.S.&nbsp;federal income tax purposes. Subject to the discussion under "&#151;&nbsp;PFIC Considerations"
below, any portion of an interest payment in excess of Enbridge's current and accumulated earnings and profits would be treated first as a nontaxable return of capital that would reduce the tax basis
of a U.S.&nbsp;holder in the Notes, and would thereafter be treated as capital gain, the tax treatment of which is discussed below under "&#151;&nbsp;Sale, Redemption, or Maturity of
Notes." Because Enbridge does not currently maintain calculations of its earnings and profits under U.S.&nbsp;federal income tax principles, it is expected that all interest payments on the Notes
will generally be reported to U.S.&nbsp;holders as&nbsp;dividends. </FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;If
you are a non-corporate U.S.&nbsp;holder, certain dividends paid to you by "qualified foreign corporations" may be taxed at favorable rates applicable to "qualified dividend
income." However, these favorable rates are available only if certain conditions are met, including a requirement that you hold the applicable security for a minimum period during which you are not
protected from the risk of loss. The IRS has ruled that where a security treated as equity for U.S.&nbsp;federal income tax purposes provides for repayment of the principal amount at maturity, a
holder's creditor rights with respect to the principal repayment may constitute protection from the risk of loss. It is not clear whether a U.S.&nbsp;holder's right to receive the principal amount
of the Notes at maturity should be treated as providing for protection from risk of loss for this purpose in light of the fact that the Notes provide for the possible Automatic Conversion into
Conversion Preferred Shares. It is accordingly unclear whether interest payments on the Notes will constitute "qualified dividend income" that is subject to tax at preferential rates. If you are a
non-corporate U.S.&nbsp;holder, you should consult your tax advisor as to whether interest on the Notes will constitute "qualified dividend income." If dividends with respect to the Notes are not
qualified dividend income, then the amount of such dividends received by a U.S.&nbsp;holder (including payments received by a non-corporate U.S.&nbsp;holder) will be subject to taxation at
ordinary income tax&nbsp;rates. </FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Dividends
on the Notes will not be eligible for the dividends-received deduction generally available to U.S.&nbsp;corporations under the Code with respect to certain dividends. </FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
amount of an interest payment on the Notes will include amounts, if any, withheld in respect of Canadian&nbsp;taxes. </FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Amounts
Enbridge pays with respect to the Notes will generally be considered foreign-source income to U.S.&nbsp;holders. Subject to applicable limitations, some of which vary depending
upon the circumstances of a particular U.S.&nbsp;holder, Canadian income taxes withheld from interest payments on the Notes to a U.S.&nbsp;holder not eligible for an exemption from Canadian
withholding tax (under the Canada-United&nbsp;States Tax Convention or otherwise) will be creditable against the U.S.&nbsp;holder's U.S.&nbsp;federal income tax liability. The rules governing
foreign tax credits are complex, and U.S.&nbsp;holders are urged to consult their own tax advisors regarding the creditability of foreign taxes in their particular circumstances. </FONT></P>

</UL>

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Subject to the discussion under "&#151;&nbsp;PFIC Considerations" below, U.S.&nbsp;holders will generally recognize
gain or loss upon the sale of their Notes in an amount equal to the difference between the amount they receive at such time and their tax basis in the Notes. Generally, such gain or loss will be
capital gain or loss. In general, the tax basis of a U.S.&nbsp;holder in its Notes will be equal to the price such holder paid for them, subject to reduction (if&nbsp;applicable) as described
above under "&#151;&nbsp;Payments of Interest." Such capital gain or loss will be long-term capital gain or loss if the U.S.&nbsp;holder will have held its Notes for more than one
year at the time of the sale of its Notes. Long-term capital gain of a non-corporate U.S.&nbsp;holder is generally taxed at preferential rates. The deductibility of capital losses is subject to
limitations under the Code. Such gain or loss will generally be income or loss from sources within the United&nbsp;States for foreign tax credit limitation purposes. Consequently,
U.S.&nbsp;holders may not be able to use any foreign tax credits arising from any Canadian tax imposed on the sale, exchange or other taxable disposition of Notes unless such credit can be applied
(subject to applicable limitations) against tax due on other income treated as derived from foreign sources or unless an applicable treaty provides otherwise. </FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
redemption of the Notes for cash and the receipt of cash upon maturity of the Notes will be treated for U.S.&nbsp;federal income tax purposes as a sale or exchange, taxable as
described in the preceding paragraph, if, as is likely in most cases, the redemption or maturity is "not essentially equivalent to a dividend" or "in complete redemption" of a U.S.&nbsp;holder's
interest in Enbridge's Notes and other instruments of Enbridge treated as equity for U.S.&nbsp;federal income tax purposes, or, in the case of non-corporate U.S.&nbsp;holders, "in partial
liquidation" of Enbridge, each of the above within the meaning of Section&nbsp;302(b) of the Code. If none of the above standards is satisfied, then a payment in redemption
or upon maturity of the Notes will be treated as a distribution subject to the tax treatment described above under "&#151;&nbsp;Payments of&nbsp;Interest". </FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;If
you receive any foreign currency on the sale of Notes, you may recognize ordinary income or loss as a result of currency fluctuations between the date of the sale of Notes and the
date the sale proceeds are converted into U.S.&nbsp;dollars. </FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;U.S.&nbsp;holders
are strongly encouraged to consult their own tax advisors regarding the characterization of a redemption payment under the rules described in this subsection and the
consequences of such characterization to such&nbsp;holders. </FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2><I> Automatic Conversion of Notes  </I></FONT></P>

</UL>

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Automatic Conversion of Notes into Conversion Preferred Shares should be treated as a recapitalization for U.S.&nbsp;federal
income tax purposes. As a result, upon such Automatic Conversion, U.S.&nbsp;holders should not recognize any gain or loss, their basis in the Conversion Preferred Shares received should be equal to
their basis in the Notes which were converted and their holding period in the Conversion Preferred Shares received should include the holding period of the Notes which were converted. Distributions on
the Conversion Preferred Shares will be taxed as described under "&#151;&nbsp;Payments of Interest," above. </FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2><I> PFIC Considerations  </I></FONT></P>

</UL>

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Enbridge believes it currently is not and does not expect to be a passive foreign investment company
("</FONT><FONT SIZE=2><I>PFIC</I></FONT><FONT SIZE=2>") for U.S.&nbsp;federal income tax purposes, and therefore believes that the Notes should not be treated as stock of a PFIC, but this
conclusion is a factual determination made annually and thus may be subject to change. In general, Enbridge will be a PFIC with respect to a U.S.&nbsp;holder if, for any taxable year in which such
holder held the Notes, either (i)&nbsp;at least 75&nbsp;percent of the gross income of Enbridge for the taxable year was passive income or (ii)&nbsp;at least 50&nbsp;percent of the value,
determined on the basis of a quarterly average, of Enbridge's assets was attributable to assets that produce or are held for the production of passive income (including cash). If Enbridge were to be

disposition of Notes would in general not be treated as capital gain. Instead, a U.S.&nbsp;holder would be treated as if it had realized such gain ratably over its holding period for the
Notes. Amounts allocated to the year of disposition and to years before Enbridge became a PFIC would be taxed as ordinary income and amounts allocated to each other taxable year would be taxed at the
highest tax rate applicable to individuals or corporations, as appropriate, in effect for each such year to which the gain was allocated, together with an interest charge in respect of the tax
attributable to each such year. Further, to the extent that any distribution received by a U.S.&nbsp;holder on its Notes exceeded 125&nbsp;percent of the average of the annual distributions on the
Notes received during the preceding three years or the holder's holding period, whichever is shorter, the distribution would be subject to taxation in the same manner as a gain, such manner being
described immediately above. With certain exceptions, a U.S.&nbsp;holder's Notes will be treated as stock in a PFIC if Enbridge was a PFIC at any time during such holder's holding period for the
Notes. In addition, dividends that a U.S.&nbsp;holder receives from Enbridge would not constitute qualified dividend income to such holder if Enbridge were a PFIC (or&nbsp;were treated as a PFIC
with respect to such holder) either in the taxable year of the distribution or the preceding taxable&nbsp;year. </FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;As discussed above, it is possible that Notes could be treated as debt of Enbridge for U.S.&nbsp;federal income tax purposes. If the
Notes were so treated, and the Notes are not treated as contingent payment debt instruments, a United&nbsp;States holder would be required to include the interest payments on the Notes as ordinary
interest income. Furthermore, in such case, the Notes may be treated as a contingent payment debt instrument, in which case (i)&nbsp;a United&nbsp;States holder would be required to accrue
interest on the Notes even if it is otherwise subject to the cash basis method of accounting for tax purposes, and (ii)&nbsp;a United&nbsp;States holder would be required to treat any gain that it
recognizes upon the sale, exchange, redemption, or maturity of its Notes as ordinary income that does not qualify for preferential rates of taxation. In addition, even if the Notes are not treated as
contingent payment debt instruments, the Notes could be treated as issued with original issue discount, in which case (i)&nbsp;a United&nbsp;States holder that is otherwise subject to the cash
basis method of accounting may be required to accrue interest on the Notes, and (ii)&nbsp;a United&nbsp;States holder would be required to include deferred interest in income before the receipt of
such deferred interest. </FONT></P>

Harcourt&nbsp;LLP, Canadian counsel to the underwriters, the following is a summary of the principal Canadian federal income tax considerations generally applicable to a holder of Notes who acquires
Notes under any offering hereunder and who, for purposes of the </FONT><FONT SIZE=2><I>Income Tax&nbsp;Act</I></FONT><FONT SIZE=2> (Canada) and at all relevant times, (i)&nbsp;is not, and is not
deemed to be, resident in Canada; (ii)&nbsp;deals at arm's length with and is not affiliated with the Corporation or any of its affiliates; (iii)&nbsp;deals at arm's length with any transferee

subsection&nbsp;18(5) of the </FONT><FONT SIZE=2><I>Income Tax&nbsp;Act</I></FONT><FONT SIZE=2> (Canada)) of the Corporation (a&nbsp;"Non-Resident Holder"). Special rules, which are not
discussed in this summary, may apply to certain Non-Resident Holders that are insurers carrying on an insurance business in Canada and&nbsp;elsewhere. </FONT></P>

into account or anticipate any changes in law or CRA administrative policies and assessing practices, whether by way of legislative, governmental or judicial decision or action, nor does it take into

involves syndicate sales of Notes in excess of the principal amount of Notes to be purchased by the underwriters in the offering, which creates a syndicate short position. Syndicate covering
transactions involve purchases of the Notes in the open market after the distribution has been completed in order to cover syndicate short positions. Stabilizing transactions consist of certain bids

commence any of these transactions, they may discontinue them at any time. There will be no obligation on J.P. Morgan Securities&nbsp;LLC, HSBC&nbsp;Securities (USA)&nbsp;Inc. and Merrill Lynch,

estimate that our total expenses for this offering, excluding underwriting commissions, will be US$&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;. </FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
underwriters or their affiliates perform and have performed commercial banking, investment banking and advisory services for us from time to time for which they receive and have
received customary fees and expenses. The underwriters may, from time to time, engage in transactions with and perform services for us in the ordinary course of their business. In addition, in the
ordinary course of their business activities, the underwriters and their affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or&nbsp;related
derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers. Such investments and securities activities may involve securities
and/or instruments of ours or our affiliates. The underwriters and their affiliates may also make investment recommendations and/or publish or express independent research views in respect of such
securities or financial instruments and may hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments. </FONT></P>


<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Certain
of the underwriters are affiliates of banks that are currently lenders to us (the&nbsp;"Lenders") under credit facilities extended to the Corporation or its subsidiary,
Enbridge (U.S.)&nbsp;Inc. (the&nbsp;"Enbridge Credit Facilities") and as a result under applicable Canadian securities legislation we may be considered to be a connected issuer to such
underwriters. We are in compliance with the terms of the Enbridge Credit Facilities and none of the Lenders were involved in the decision to offer the Notes or in the determination of the terms of the
distribution of the&nbsp;Notes. </FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We
may have outstanding existing indebtedness owing to certain of the underwriters and affiliates of such underwriters, a portion of which we may repay with the net proceeds of this
offering. See "Use of Proceeds." As a result, one or more of such underwriters or their affiliates may receive more than 5% of the net proceeds from this offering in the form of the repayment of such
existing indebtedness. Accordingly, this offering is being made pursuant to Rule&nbsp;5121 of the Financial Industry Regulatory Authority,&nbsp;Inc. Pursuant to this rule, the appointment of a
qualified independent underwriter is not necessary in connection with this offering, because the conditions of Rule&nbsp;5121(a)(1)(C) are&nbsp;satisfied. </FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;If
any of the underwriters or their affiliates has a lending relationship with us or our affiliates, certain of those underwriters or their affiliates routinely hedge, certain other of
those underwriters or their affiliates have hedged and are likely in the future to hedge, and certain other of those underwriters of
their affiliates may hedge, their credit exposure to us consistent with their customary risk management policies. Typically, these underwriters and their affiliates would hedge such exposure by
entering into transactions which consist of either the purchase of credit default swaps or the creation of short positions in our affiliates' securities, including potentially the Notes offered
hereby. Any such credit default swaps or short positions could adversely affect future trading prices of the Notes offered&nbsp;hereby. </FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We
have agreed to indemnify the underwriters against certain liabilities, including liabilities under the U.S.&nbsp;Securities Act, or to contribute to payments the underwriters may be
required to make because of any of those liabilities. </FONT></P>

expect that delivery of the Notes will be made against payment therefor on or about the date specified on the cover page of this prospectus supplement, which will be the fifth

generally are required to settle in three business days, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade Notes on the date of this prospectus
supplement or the next succeeding business day will be required, by virtue of the fact that the Notes initially will settle in T+5, to specify an alternate settlement cycle at the time of any such
trade to prevent a failed settlement. Purchasers of the Notes who wish to make such trades should consult their own&nbsp;advisor. </FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;This Prospectus, including documents incorporated by reference into this Prospectus, contain both historical and forward-looking
statements within the meaning of Section&nbsp;27A of the U.S.&nbsp;Securities Act and Section&nbsp;21E of the U.S.&nbsp;Exchange Act. This information has been included to provide readers with
information about the Corporation and its subsidiaries, including management's assessment of Enbridge's and its subsidiaries' future plans and operations. This information may not be appropriate for
other purposes. Forward-looking statements are typically identified by words such as "anticipate", "expect", "project", "estimate", "forecast", "plan", "intend", "target", "believe", "likely" and
similar words suggesting future outcomes or statements regarding an outlook. Forward-looking information or statements included or incorporated by reference in this Prospectus include, but are not
limited to, statements with respect to the following: expected earnings before interest and taxes ("</FONT><FONT SIZE=2><B>EBIT</B></FONT><FONT SIZE=2>") or expected adjusted EBIT; expected
earnings/(loss) or adjusted earnings/(loss); expected earnings/(loss) or adjusted earnings/(loss) per share; expected available cash flow from operations
("</FONT><FONT SIZE=2><B>ACFFO</B></FONT><FONT SIZE=2>"); expected future cash flows; expected costs related to projects under construction; expected in-service dates for projects under construction;
expected capital expenditures; expected equity funding requirements for the Corporation's commercially secured growth program; estimated future dividends; expected future actions of regulators;
expected costs related to leak remediation and potential insurance recoveries; expectations regarding commodity prices; supply forecasts; expectations regarding the impact of the dividend payout
policy and dividend payout expectation; and strategic alternatives currently being evaluated in connection with the United&nbsp;States sponsored vehicles strategy. </FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Although
Enbridge believes these forward-looking statements are reasonable based on the information available on the date such statements are made and processes used to prepare the
information, such statements are not guarantees of future performance and readers are cautioned against placing undue reliance on forward-looking statements. By their nature, these statements involve
a variety of assumptions, known and unknown risks and uncertainties and other factors, which may cause actual results, levels of activity and achievements to differ materially from those expressed or
implied by such statements. Material assumptions include assumptions about the following: the expected supply of and demand for crude oil, natural gas, natural gas liquids
("</FONT><FONT SIZE=2><B>NGL</B></FONT><FONT SIZE=2>") and renewable energy; prices of crude oil, natural gas, NGL and renewable energy; exchange rates; inflation; interest rates; availability and
price of labour and construction materials; operational reliability; customer and regulatory approvals; maintenance of support and regulatory approvals for the Corporation's projects; anticipated
in-service dates; weather; impact of the dividend policy on the Corporation's future cash flows; credit ratings; capital project funding; expected EBIT or expected adjusted EBIT; expected
earnings/(loss) or adjusted earnings/(loss); expected earnings/(loss) or adjusted earnings/(loss) per share; expected future cash flows and expected future ACFFO; and estimated future dividends. </FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Assumptions
regarding the expected supply of and demand for crude oil, natural gas, NGL and renewable energy, and the prices of these commodities, are material to and underlie all
forward-looking statements. These factors are relevant to all forward-looking statements as they may impact current and future levels of demand for the Corporation's services. Similarly, exchange
rates, inflation and interest rates impact the economies and business environments in which the Corporation operates and may impact levels of demand for the Corporation's services and cost of inputs,
and are therefore inherent in all forward-looking statements. Due to the interdependencies and correlation of these macroeconomic factors, the impact of any one assumption on a forward-looking
statement cannot be determined with certainty, particularly with respect to expected EBIT, adjusted EBIT, earnings/(loss), adjusted earnings/(loss) and associated per share amounts, ACFFO or estimated
future dividends. The most relevant assumptions associated with forward-looking statements on projects under construction, including estimated completion dates and expected capital expenditures,
include the following: the availability and price of labour and construction materials; the effects of inflation and foreign exchange rates on </FONT></P>

associated with the current year earnings, relative to the low consolidated earnings. For comparability, if the 2014 effective income tax rate was used instead of the 2015 effective income tax rate,
the Corporation's dividend requirements for the 12&nbsp;months ended December&nbsp;31, 2015 would have been approximately $398&nbsp;million and the earnings coverage ratio would have been
0.8&nbsp;times the Company's aggregate dividend and interest requirements for this period. This would result in the Corporation's earnings coverage ratio for the 12&nbsp;month period ended
December&nbsp;31, 2015 being less than one-to-one. Additional earnings before interest and income tax for the 12&nbsp;months ended December&nbsp;31, 2015 of $366&nbsp;million would be required
to achieve a one-to-one earnings coverage&nbsp;ratio. </FONT></DD></DL>

other than as described below, the specific terms of the depository arrangement with respect to any portion of a particular series of debt securities to be represented by a Global
Security will be described in the Prospectus Supplement relating to such series. The Corporation anticipates that the following provisions will apply to all depository arrangements. </FONT></P>


<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Upon
the issuance of a Global Security, the Depositary therefor will credit, on its book entry and registration system, the respective principal amounts of the debt securities
represented by the Global Security to the accounts of such persons having accounts with such Depositary ("</FONT><FONT SIZE=2><B>participants</B></FONT><FONT SIZE=2>"). Such accounts shall be
designated by the underwriters, dealers or agents participating in the distribution of the debt securities or by Enbridge if such debt securities are offered and sold directly by the Corporation.
Ownership of beneficial interests in a Global Security will be limited to participants or persons that may hold beneficial interests through participants. Ownership of beneficial interests in a Global
Security will be shown on, and the transfer of that ownership will be effected only through, records maintained by the Depositary therefor (with respect to interests of participants) or by
participants or persons that hold through participants (with respect to interests of persons other than participants). The laws of some states in the United&nbsp;States may require that certain
purchasers of securities take physical delivery of such securities in definitive&nbsp;form. </FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;So
long as the Depositary for a Global Security or its nominee is the registered owner of the Global Security, such Depositary or such nominee, as the case may be, will be considered the
sole owner or holder of the debt securities represented by the Global Security for all purposes under the Indenture. Except as provided below, owners of beneficial interests in a Global Security will
not be entitled to have debt securities of the series represented by the Global Security registered in their names, will not receive or be entitled to receive physical delivery of debt securities of
such series in definitive form and will not be considered the owners or holders thereof under the&nbsp;Indenture. </FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Beneficial
owners will not receive certificates representing their ownership interests in debt securities, except in the event that use of the book-entry system for the debt securities
is discontinued or if there shall have occurred and be continuing an Event of Default under the Indenture. The Depositary will have no knowledge of the actual beneficial owners of the debt securities;
the Depositary's records will reflect only the identity of the direct participants to whose accounts the debt securities are credited, which may or may not be the beneficial owners. The direct and
indirect participants will remain responsible for keeping account of their holdings on behalf of their customers. </FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Any
payments of principal, premium, if any, and interest on Global Securities registered in the name of a Depositary or its nominee will be made to the Depositary or its nominee, as the
case may be, as the registered owner of the Global Security representing such debt securities. None of Enbridge, the Trustee or any paying agent for debt securities represented by the Global
Securities will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests of the Global Security or for maintaining,
supervising or reviewing any records relating to such beneficial ownership interests. </FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
