FOR IMMEDIATE RELEASE

OCTOBER 24, 2001

Third Quarter 2001 (For the period ended September 30, 2001)

                     SUNCOR ENERGY GROWTH STRATEGY ON TRACK
                         PROJECT MILLENNIUM PRODUCES OIL

THIRD QUARTER SUMMARY

ALL FINANCIAL FIGURES ARE IN CANADIAN DOLLARS UNLESS NOTED OTHERWISE. NATURAL
GAS CONVERTS TO BARRELS OF OIL EQUIVALENT AT A 6:1 RATIO (SIX MILLION CUBIC
FEET OF NATURAL GAS CONVERTS TO ONE BARREL OF OIL EQUIVALENT). THE FOLLOWING
SUMMARY IS QUALIFIED BY THE MANAGEMENT'S DISCUSSION & ANALYSIS.

-    Third quarter net earnings were $73 million, up from $50 million in the
     third quarter of 2000. Cash flow from operations for the quarter was $177
     million, compared with $229 million during the same period last year.

-    Net earnings for the first nine months of 2001 were $362 million, compared
     with net earnings of $266 million for the same period in 2000. Cash flow
     from operations for the first nine months of 2001 was $698 million,
     compared with $742 million during the same period in 2000.

-    Suncor's production during the third quarter averaged 149,700 barrels of
     oil equivalent (BOE) per day, compared with 153,900 BOE per day during the
     same period last year. The nine-month production average was 146,400 BOE
     per day, compared with 157,800 BOE per day during the same period in 2000.

-    Project Millennium construction is nearly complete and commissioning of all
     the new facilities is on schedule.

-    On October 17 oil was produced for the first time from the new upgrader.
     This marked an important milestone in the commissioning of the project and
     Suncor's goal to increase oil production capacity to 225,000 barrels per
     day by year-end.

-    During the quarter Suncor issued $500 million of 10-year Medium Term Notes,
     which was applied to repay existing borrowings.

DECLINING COMMODITY PRICES IMPACTS THIRD QUARTER OPERATIONAL EARNINGS

Suncor Energy Inc. reported third quarter net earnings of $73 million, up from
$50 million in the third quarter of 2000. Operational earnings for the quarter
were $100 million, compared to operational earnings of $111 million in the third
quarter of 2000.

<PAGE>


Cash flow from operations for the quarter was $177 million, compared with $229
million during the same period last year. Operational cash flow in the quarter
was $238 million compared to $252 million during the third quarter of 2000.

Net earnings for the first nine months of 2001 were $362 million, compared with
net earnings of $266 million for the same period in 2000. Year-to-date
operational earnings were $363 million compared to operational earnings of $306
million for the same period last year.

Cash flow from operations for the first nine months of 2001 was $698 million,
compared with $742 million during the same period last year. Year-to-date
operational cash flow was $819 million, compared to $773 million for the same
period last year.

Suncor's production during the third quarter averaged 149,700 barrels of oil
equivalent (BOE) per day, compared with 153,900 BOE per day the year before. The
nine-month production average for 2001 was 146,400 BOE per day, compared with
157,800 BOE per day during the same period in 2000. The decline in production
was due to a nine-day maintenance shutdown at Oil Sands during the second
quarter and property divestments in Natural Gas last year.

"The decline in commodity prices can be seen in our operational earnings for the
quarter," said Rick George, president and chief executive officer. "But Suncor
is focused on a strategy to deliver shareholder value for the long term. Through
increased production and lower operating costs our plan is to consistently
deliver improved results even through changes in market cycles."

PROJECT MILLENNIUM PRODUCES OIL

Suncor's growth plan hit a significant milestone on October 17 when portions of
the new upgrader, built as part of Project Millennium, produced oil for the
first time.

"During the past three months, Suncor reached a variety of operational
achievements almost every day. Mining and extraction were the first to cross the
finish line when our new plants processed the first oil sands ore from the
Millennium mine," said George. "But it was when we produced the first oil from
the upgrading plants' cokers that we celebrated that Project Millennium's
construction phase had nearly ended and a new beginning of expanded production
for Suncor was underway."

Project Millennium commissioning will continue for the balance of the year with
a goal of increasing production capacity to 225,000 barrels per day by 2002.

"Although first oil production is an important step, we're still focused on
wrapping up construction and working towards completing all plant
commissioning," said George. "Steady, reliable production is our goal as we work
to provide an additional 40 million barrels per year of oil to the North
American energy market.

"Over the next few months we can expect some challenges and most likely, some
volatility in production. However, we're on the home stretch for achieving our
growth plans and our vision of doubling oil production."

ANALYSIS OF CONSOLIDATED STATEMENTS OF EARNINGS AND CASH FLOW

Net earnings for the quarter were $73 million, compared to $50 million for the
third quarter of 2000. Operational earnings for the quarter were $100 million,
compared to operational earnings of $111 million during the third quarter of
2000. The $11 million decrease in operational earnings was primarily due to
weaker commodity prices and margins that reduced earnings in all of Suncor's
operating businesses. The weakening demand for oil and natural gas along with
higher supply have reduced commodity prices and downstream margins. In addition,
lower foreign exchange gains and higher operating costs also had an unfavourable
impact on earnings.

The negative impact of lower commodity prices was partially offset by lower
hedging losses, lower Alberta crown royalties with respect to Oil Sands sales
and a weaker Canadian dollar versus the U.S. dollar.

Operational cash flow in the third quarter was $238 million, compared to $252
million in the same period of 2000. The decrease was primarily due to reduced
earnings.

Net earnings for the first nine months of 2001 were $362 million, compared to
$266 million for the same nine-month period in 2000. Year-to-date operational
earnings in 2001 were $363 million, compared to $306 million during the first
nine months of 2000. The $57 million increase in operational earnings in the
first nine months of 2001 was primarily due to improved commodity prices and
margins, lower crude oil hedging losses, lower exploration expenses, lower
Alberta crown royalties and a weaker Canadian dollar versus the U.S. dollar.
Partially offsetting these factors were lower upstream sales volumes, higher
operating expenses, widening of light/heavy crude oil differential, lower
foreign exchange gains and higher interest expenses.

Year-to-date operational cash flow was $819 million, compared to $773 million
for the same period of 2000. Year-to-date operational cash flow for 2001 was
higher compared to 2000 because of increased earnings and the favourable income
tax impact as a result of the sale of the company's interest in the Stuart Oil
Shale Project. These benefits were partially reduced by the recognition of the
estimated payment in 2002 under Suncor's long-term employee compensation
programs. The final payout under these compensation programs will be based on
the market price of Suncor's shares in 2002 and in some cases, achieving certain
performance targets in 2001. As such, the final payout is subject to measurement
uncertainty and volatility in both earnings and the ultimate cash payment. For
reporting purposes the payouts have been allocated among the company's business
units, with the exception of the estimated payouts to senior executives that
have been allocated to the Corporate segment.

SEGMENTED EARNINGS AND CASH FLOW ANALYSIS

OIL SANDS

Oil Sands recorded third quarter net earnings of $69 million, compared with $76
million earned during the third quarter of 2000.


                                       6
<PAGE>


Operational earnings in the quarter were $97 million, which excludes $28 million
in Project Millennium start-up costs. Operational earnings in the third quarter
of 2000 were $82 million, which excluded $6 million in Project Millennium
start-up costs. Operational earnings were higher by $15 million due to higher
sales volumes and lower royalty and income tax rates. The lower royalties
reflect both lower prices as well as a decreased Alberta crown royalty rate
(effective January 1, 2001), which was reduced to one per cent of gross revenues
compared to five per cent in the same period last year.

These positive factors were partially offset by lower crude prices and higher
operating expenses. The impact of lower benchmark crude oil prices was also
exacerbated in both the quarter and on a year-to-date basis due to the widening
of the light/heavy crude oil differential compared to prices received last year.
The impact of these pricing factors was partially dampened by a weaker Canadian
dollar versus the U.S. dollar.

Cash flow from operations for the quarter was $139 million, compared to $156
million during the third quarter of 2000.

Operational cash flow in the quarter was $199 million, which excludes $60
million in Project Millennium start-up costs. For the same period in 2000
operational cash flow was $178 million, which excludes $22 million in start-up
costs. The increase in operational cash flow primarily reflects the higher
earnings level.

Year-to-date net earnings for the first nine months of 2001 were $246 million,
compared to the $247 million earned during the first nine months of 2000.

Year-to-date operational earnings in 2001 of $257 million exclude Project
Millennium start-up costs and a $31 million favourable adjustment to future
income tax balances. Operational earnings in 2000 of $253 million also exclude
start-up costs. Factors positively impacting 2001 operational earnings were the
lower Alberta crown royalty rate, the reduced income tax rate and a favourable
$12 million (after-tax) impact of a pricing adjustment calculated retroactively
to the third quarter of 1999, related to a large supply contract. These factors
were partially offset by lower sales volumes, which reflect the impact of a
nine-day planned maintenance shutdown in the second quarter and higher operating
costs.

Year-to-date cash flow from operations for 2001 was $396 million compared to
$536 million in the same period last year.

Year-to-date operational cash flow was $516 million compared to $558 million in
2000. The decrease primarily reflects higher reclamation spending and the
recognition of estimated employee long-term compensation program payments (as
described above).

Oil Sands production during the third quarter averaged 116,500 barrels of oil
per day, higher than the 114,200 barrels of oil per day achieved during the same
period last year. Sales during the quarter averaged 117,800 barrels per day,
compared with 112,900 barrels per day during the third quarter of 2000.
Year-to-date production for Oil Sands averaged 113,200 barrels per day, a
decrease from the 115,300 barrels of oil averaged during the first nine months
of 2000. The decline in production was due to a nine-day maintenance shutdown in
the second quarter.


                                       7
<PAGE>


OUTLOOK

Commissioning and start-up remains on schedule to increase production capacity
to 225,000 barrels per day by year-end. Suncor has revised the fourth quarter
production estimate to be 155,000 to 165,000 barrels per day due to an
unscheduled outage at Oil Sands which occurred in October. Due to the
anticipated volatility in production during the fourth quarter, the company will
provide an update on this production forecast in late November. The impact of
this month's base plant maintenance shutdown will also be included in the
November update.

Oil Sands base plant cash operating costs for the year currently average $13.00
per barrel as compared to $11.90 per barrel in the same period last year. The
increase is primarily due to higher energy costs and increased estimated
employee short-term and long-term compensation program costs and lower sales.

During the third quarter, Oil Sands made significant progress toward
commissioning Project Millennium and increasing the production capacity of the
plant to 225,000 barrels per day. The hydrogen plant went into production and
significant portions of the extraction facilities, the cokers, sulphur trains,
the naphtha hydrotreater and supporting utilities were commissioned.

By October 15, Millennium extraction operations had successfully produced about
two million barrels of bitumen. On October 17 oil production occurred for the
first time from the Millennium upgrader. Project Millennium commissioning will
continue during the balance of the year.

NATURAL GAS

Natural Gas recorded third quarter net earnings of $13 million, compared with
$43 million earned during the third quarter of 2000.

Operational earnings in the quarter were $12 million, compared to $18 million in
the third quarter of 2000. The $6 million decrease was due to lower commodity
prices, with natural gas prices 16 per cent lower than the third quarter of
2000, and lower production. Partially offsetting these unfavourable factors were
lower expenses reflecting last year's restructuring and divestment activities.


                                       8
<PAGE>


Natural gas prices have declined from the first half of this year, due to higher
supply and weaker demand in the North American natural gas market.

Cash flow from operations for the third quarter of 2001 was $42 million, down
from the $64 million reported in the third quarter of 2000. The decrease was
primarily due to lower production volumes and commodity prices.

Year-to-date net earnings were $105 million, compared to the $67 million earned
during the first nine months of 2000.

Year-to-date operational earnings in 2001 were $95 million (excluding a $9
million favourable adjustment to future income tax balances and $1 million from
restructuring). This compares to $28 million in operational earnings for the
first nine months of 2000. This $67 million increase was primarily due to higher
natural gas prices, a weaker Canadian dollar and lower expenses reflecting last
year's restructuring and divestment activities. Natural gas prices were higher
due to strong supply and demand fundamentals and significant exposure to the
high value California market. Earnings were also favourably impacted by a $4
million benefit associated with the reduction in the Alberta income tax rate in
2001.

Cash flow from operations for the first nine months of the year was $245
million, up from the $154 million reported in the same period in 2000. The
increase primarily reflects higher commodity prices partially offset by lower
volumes and the recognition of estimated employee long-term compensation program
payments (as described above).

Production averaged 33,200 BOE per day in the third quarter compared with 39,700
BOE per day during the third quarter last year. Natural gas production in the
third quarter of 2001 averaged 176 million cubic feet (mmcf) per day down from
200 mmcf per day in the third quarter of 2000. Natural gas production during the
first nine months of 2001 averaged 176 mmcf per day down from 206 mmcf per day
in the first nine months of 2000. This decrease in production was due to
property divestments that occurred in 2000.

SUNOCO

Sunoco's third quarter net earnings were $12 million, compared with $19 million
in the same quarter of 2000.

Sunoco's Rack-Back business reported earnings for the third quarter of $8
million compared to $21 million in the same quarter of 2000. The earnings
decline was primarily attributable to softening product demand.

Refining margins weakened during the third quarter due to declining product
demand. Refining margins fell to an average of 4.3 cents per litre (cpl) in the
third quarter, compared to 6.1 cpl in the same period last year.


                                       9
<PAGE>


Sunoco's Rack-Forward business reported earnings of $4 million compared to a
loss of $2 million in the third quarter of 2000. The improvement was primarily
attributable to higher retail natural gas margins due to the restructuring of
customer contracts and improved margins in the industrial/commercial sales
channel. Partially offsetting these favourable factors were lower retail
gasoline margins. The ongoing competitiveness of the market saw retail gasoline
margins decline to an average of 5.9 cpl in the third quarter of 2001 compared
with 6.4 cpl in the same period last year.

Sunoco's cash flow from operations for the quarter decreased to $30 million for
the quarter compared with $49 million in the same period last year. The decline
primarily reflects the lower refining margins received.

Sunoco reported net earnings of $80 million for the first nine months of 2001,
compared to $58 million in the same period in 2000.

Sunoco's year-to-date operational earnings of $70 million exclude a $10 million
favourable income tax rate adjustment. Operational earnings for the same period
in 2000 were $51 million, which excludes a $7 million favourable income tax rate
adjustment.

Year-to-date Rack Back operational earnings totalled $55 million compared with
$53 million in the same period of 2000. Higher refining margins and volumes had
a positive impact on Rack Back earnings in the first nine months of 2001.
However, increased cash operating expenses offset most of the favourable margin
and volume impact. Refinery fuel costs were higher due primarily to increased
natural gas costs and higher consumption. In addition, higher repair and
maintenance costs at the Sarnia Refinery were incurred in the first quarter due
to an unplanned outage of the catalytic cracker.

Rack Forward operational earnings were $15 million for the first nine months of
2001, compared with a loss of $2 million recorded in the same period last year.
The higher earnings were driven by improved margins and volumes on retail
natural gas sales and higher margins received from the industrial/commercial
sales channel. Retail gasoline margins in the first nine-months of this year
averaged 6.5 cpl, the same as the margins received in the same period last year.

Sunoco's year-to-date cash flow from operation increased to $147 million
compared with $133 million in the same period in 2000. The increase reflects the
higher earnings, partially offset by the recognition of the estimated payment
expected in 2002 with respect to Suncor's employee long-term compensation
programs (as described above).

CORPORATE

Corporate after tax costs during the third quarter were $21 million, compared to
$88 million for the third quarter in 2000. The third quarter of 2000 included an
$80 million write-down of oil shale assets. Excluding this write-down, corporate
costs were $13 million higher primarily due to lower foreign exchange gains and
research and development costs with respect to new technology assessments.

The cash flow from operations deficit in the quarter was $34 million compared to
$40 million in the third quarter of 2000. The decrease primarily reflects lower
estimated income tax payments.


                                       10
<PAGE>


Year-to-date after tax costs were $69 million compared to $106 million in 2000.
The improvement year-over-year is primarily for the same reasons for the
quarter-over-quarter improvement noted above, partially offset by the $9 million
impact associated with a reduction of income tax rates.

The year-to-date cash flow from operations deficit was $90 million compared to
$81 million in the same period of 2000. The increase reflects the recognition of
the estimated long-term compensation program payments (as described above) and
costs associated with the research and development assessments. These factors
were partially offset by the favourable income tax impact as a result of the
sale of the company's interest in the Stuart Oil Shale Project.

ANALYSIS OF FINANCIAL CONDITION

Excluding cash and cash equivalents, short-term borrowings and the current
portion of long-term borrowings, Suncor had a working capital deficiency of $34
million at the end of the third quarter. This is unchanged from the end of the
second quarter of this year and down from a deficiency of $128 million at the
end of 2000. The decrease primarily reflects a decline in accounts receivable
due to lower commodity prices, a reduction of outstanding liabilities reflecting
lower Project Millennium obligations, lower hedging losses and a lower level of
investment spending. Partially offsetting these favourable factors was an
increase in inventory levels from low year-end levels and an increase in
anticipation of a planned maintenance shutdown of a portion of the Sarnia
Refinery in the fourth quarter of this year.

At the end of the third quarter of 2001, net debt had risen to $2.897 billion
from $2.236 billion at the end of 2000. The increase of the net debt in the
current year primarily reflects the ongoing investing activity associated with
Project Millennium. Suncor has in place sufficient lines of credit to cover
working capital requirements and will continue to monitor the debt capital
markets for opportunities to refinance bank debt with longer-term debt. Suncor's
undrawn lines of credit as of September 30, 2001 were approximately $675
million, compared to $460 million at the end of June 2001.

In August, Suncor issued $500 million of 10-year Medium Term Notes. The funds
were added to the general funds of Suncor and have been applied principally to
repay commercial paper and bank borrowings.

SUNCOR ENERGY INC.
NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (unaudited)

1.  ACCOUNTING POLICIES
These financial statements follow the same accounting policies and methods of
computation as, and should be read in conjunction with, the most recent annual
financial statements, with the exception to the elimination of intercompany
sales as discussed in note 2.

2.  ELIMINATION OF INTERCOMPANY SALES
During the first quarter of 2001, the company changed the methodology of
accounting for sales from its upstream operations (Oil Sands and Natural Gas) to
its downstream operations (Sunoco) from a deeming concept to the actual tracking
of product shipped. This change was made to better reflect the current
operational activities within the company. This prospective change increased
sales and other operating revenues and purchases of crude oil by $134 million
for the quarter and $345 million year to date and has no impact on consolidated
and segmented net earnings in the accompanying financial statements.

3.  START-UP EXPENSES
Start-up expenses represent pre-operating costs incurred in the commissioning of
the company's Oil Sands Project Millenium.

5.  OIL SHALE PROJECT
Effective April 5, 2001, the company sold its interest in the Stuart Oil Shale
Project to joint venture co-owners Southern Pacific Petroleum NL and Central
Pacific Minerals NL(SPP/CPM). Under the terms of the purchase, the company
retains a 5% royalty interest in Stage 1 of the project and SPP/CPM and Suncor
retain world wide rights to the ATP technology. The company made total payments
as part of the transaction in the amount of $5 million (AUD$7 million), which
SPP/CPM will use to fund Stage 1 operating, capital and transition costs. The
company received 2.5 million SPP shares and 0.926 million CPM shares in
consideration. SPP/CPM issued the company 12.5 million SPP share options and 4.6
million CPM share options, exercisable over five years at a strike price of
AUD$1.25 per SPP share and AUD$3.38 per CPM share. Suncor has agreed to
surrender its partly paid Restricted Class shares (SPP 57 million and CPM 18.85
million) which were acquired in 1997.

During the second quarter of 2001, the company wrote off the carrying value of
the capital assets and extinguished the long-term borrowings and accrued
interest. The earnings impact of the sale of our remaining interest in the
project was $48 million pre-tax, $3 million after-tax.

6.  INCOME TAX RATE REDUCTION
Effective April 1, 2001, the Alberta and Ontario governments passed legislation
that reduced the provincial income tax rates. The future tax balances for the
company have been revalued at the new rates resulting in a cumulative future tax
recovery of $43 million. The new rates are reflected in the tax provisions for
the current period. The income tax rate reduction does not affect the company's
cash flow or liquidity.

</Table>

* Basic earnings per share is the net earnings attributable to common
shareholders divided by the weighted average number of common shares.

** For the quarters ended September 30, 2001 and 2000, diluted earnings per
share is the net earnings attributable to common shareholders divided by the
weighted average number of diluted common shares. Dividends on preferred
securities of $8 million in 2001 ($6 million in 2000), and preferred
securities converted of 13 million shares in 2001 (15 million shares in 2000)
have an anti-dilutive impact, therefore they are not included in the
calculation of diluted earnings per share.

*** For the nine months ended September 30, 2001, diluted earnings per share
is the net earnings before deducting dividends on preferred securities
divided by the weighted average number of diluted common shares.

**** For the nine months ended September 30, 2000, diluted earnings per share
is the net earnings attributable to common shareholders divided by the
weighted average number of diluted common shares. Dividends on preferred
securities of $19 million and preferred securities converted of 17 million
shares have an anti-dilutive impact, therefore they are not included in the
calculation of diluted earnings per share.

8.  ISSUANCE OF MEDIUM TERM NOTES
On August 21, 2001, the company issued $500 million of Series 2 Medium Term
Notes at an interest rate of 6.7%, which is payable semi-annually. The net
proceeds received were used to repay commercial paper and bank borrowings.
These notes will mature August 22, 2011.

9.  RESTRUCTURING
In 2000, the carrying value of certain assets of the company's Natural Gas
business were written down to their net estimated recoverable amount and a
provision for estimated restructuring costs was recorded.

In the third quarter of 2001, some of these properties that were previously
written down were sold, realizing a gain before tax of $3 million. Provisions
for estimated restructuring costs were also increased by $1 million before
tax to reflect increased employee termination costs.
