<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We have entered into a distribution agency agreement with US Tiger Securities,&nbsp;Inc., which we refer to as Tiger Brokers or the sales agent,
relating to our common shares, with no par value, offered by this prospectus supplement and the accompanying prospectus. In accordance with the terms of the distribution agency agreement, we may offer
and sell our common shares having an aggregate offering price of up to $150,000,000 from time to time on the Nasdaq Global Select Market or other markets for our common shares in the U.S. through
Tiger Brokers as our sales agent. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our
common shares are listed on the Nasdaq Global Select Market under the symbol "CSIQ." On May&nbsp;26, 2021, the last reported sale price of our common shares on the Nasdaq Global
Select Market was $41.00 per share. We have applied to the Nasdaq Global Select Market for the listing of the shares of our common stock being offered by this prospectus supplement and the
accompanying prospectus. Listing will be subject to us fulfilling all the listing requirements of the Nasdaq Global Select Market and is a condition of sales under the distribution agency agreement. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Sales
of our common shares, if any, under this prospectus supplement and the accompanying prospectus may be made in sales deemed to be "at-the-market offerings" as defined in
Rule&nbsp;415(a)(4) promulgated under the Securities Act of 1933, as amended, (the "Securities Act"). Tiger Brokers will make all sales using commercially reasonable efforts consistent with its
normal trading and sales practices, on mutually agreed terms between Tiger Brokers and us. Sales of the shares of our common stock, if any, through Tiger Brokers or directly to Tiger Brokers acting as
principal will be made by means of ordinary brokers' transactions on the Nasdaq Global Select Market, the existing United States trading market for our common stock, or any other existing trading
market in the United States for our common stock, sales made to or through a market maker other than on an exchange or otherwise, directly to the sales agent as principal, in negotiated transactions
with our prior approval at market prices prevailing at the time of sale or at prices related to prevailing market prices, or any other method permitted by law. If we and Tiger Brokers agree on any
method of distribution other than sales of shares of our common stock into the Nasdaq Global Select Market or another existing trading market in the United States at market prices, we will
file&nbsp;a further prospectus supplement providing all information about such offering, as required by Rule&nbsp;424(b) under the Securities Act. We may also sell shares of our common stock to
Tiger Brokers as principal for its own account, at a price per share agreed upon at the time of sale. If we sell shares to Tiger Brokers as principal, we will enter into a separate terms agreement
setting forth the terms of such transaction, and we will describe the agreement in a separate prospectus or pricing supplement. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Tiger
Brokers is not required to sell any specific number or dollar amount of shares of our common stock, but, subject to the terms and conditions of the distribution agency agreement
and unless otherwise agreed by us and Tiger Brokers, Tiger Brokers will use its commercially reasonable efforts to sell the shares offered as our sales agent. There is no arrangement for funds to be
received in any escrow, trust or similar arrangement. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We
also may sell some or all of the common shares to the sales agent as principal for its own account at a price per share agreed upon at the time of sale. If we sell common shares to
the sales agent as principal, we will enter into a separate terms agreement setting forth the terms of such transaction, and we will describe the agreement in a separate prospectus supplement or
pricing supplement. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
sales agent will be entitled to certain compensation in connection with the sale of our common shares on our behalf. As a result, the sales agent may be deemed to be an "underwriter"
within the meaning of the Securities Act of 1933, as amended, and the compensation of the sales agent may be deemed to be underwriting commissions or discounts. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;This prospectus supplement and the information incorporated herein by reference may contain "forward-looking" statements intended to qualify for
the safe harbor from liability established by the Private Securities Litigation Reform Act of 1995. These statements, which are not statements of historical fact, may contain estimates, assumptions,
projections and/or expectations regarding future events, which may or may not occur. Words such as "anticipate," "believe," "could," "estimate," "expect," "intend," "may," "plan," "potential,"
"should," "will," "would," or similar expressions, which refer to future events and trends, identify forward-looking statements. For instance, we make forward-looking statements such as our expected
manufacturing capacity, our estimated silicon raw material requirements and average selling price of our standard solar module. We do not guarantee that the transactions and events described in this
prospectus supplement and the accompanying prospectus will happen as described or that they will happen at all. You should read this prospectus supplement and the accompanying prospectus completely
and with the understanding that actual future results may be materially different from what we expect. The forward-looking statements made in this prospectus supplement relate only to events as of the
date on which the statements are made. We undertake no obligation, beyond that required by law, to update any forward-looking statement to reflect events or circumstances after the date on which the
statement is made, even though our situation may change in the future. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Whether
actual results will conform to our expectations and predictions is subject to a number of risks and uncertainties, many of which are beyond our control, and reflect future
business decisions that are subject to change. Some of the assumptions, future results and levels of performance expressed or implied in the forward-looking statements we make inevitably will not
materialize, and unanticipated events may occur which will affect our results. The "Risk Factors" section of this prospectus supplement directs you to a description of the principal contingencies and
uncertainties to which we believe we are subject. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;This
prospectus supplement also contains or incorporates by reference data related to the solar power market in several countries, including China. These market data, including industry
demand and product pricing, include projections that are based on a number of assumptions. Demand for solar generated electricity may not ultimately increase at the rates expected, or at all. The
failure of the market to grow at the projected rates may materially and adversely affect our business and the market
price of our securities. In addition, the rapidly changing nature of the solar power market and related regulatory regimes subjects any projections or estimates relating to the growth prospects or
future condition of our market to significant uncertainties. If any one or more of the assumptions underlying the market data proves to be incorrect, actual results may differ from the projections
based on these assumptions. You should not place undue reliance on these forward-looking statements. </FONT></P>

About Canadian Solar&nbsp;Inc.  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We are one of the world's largest solar power companies and a leading vertically-integrated provider of solar power products, services and
system solutions with operations in North America, South America, Europe, South Africa, the Middle East, Australia and Asia. We are continued in British Columbia, Canada, and conduct most of our
manufacturing operations in China and Southeast Asia. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our
business consists of the following two business segments: CSI Solar segment and Global Energy segment. Our CSI Solar Segment involves the design, development, manufacturing and sale
of a wide range of solar power products, including solar modules, solar system kits, battery energy storage solutions, China energy (including solar projects, EPC services and electricity revenue in
China), and other materials, components and services (including EPC). Our Global Energy Segment primarily consists of global solar and energy storage power projects (excluding China), O&amp;M and asset
management services, global electricity revenue (excluding China), as well as other development services. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Under
our CSI Solar business segment, we design, develop and manufacture solar ingots, wafers, cells, modules and other solar power products. Our solar power products include standard
solar modules and specialty solar products. Our products include a range of solar modules built to general specifications for use in a wide range of residential, commercial and industrial solar power
generation systems. Specialty solar products consist of customized solar modules that our customers incorporate into their own products and complete specialty products, such as portable solar home
systems. We employ a flexible, vertically integrated business model that combines internal manufacturing capacity with direct material purchases of both cells and wafers. We believe this approach has
benefited us by lowering the cost of materials of our solar module products. We also believe that this approach provides us with greater flexibility to respond to short-term demand increases. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our
competitive advantage is driven by our strong brand, defined as being rated the number one "most bankable brand" by Bloomberg New Energy Finance over the past four consecutive annual
bankability surveys. We also have one of the most globally diverse end markets, shipping to over 70&nbsp;countries on an average quarter, including the U.S., Japan, China, Vietnam, Brazil, Spain,
Australia, Germany, Mexico,
Canada and the Netherlands. Our customers are primarily distributors, system integrators, project developers and installers/EPC companies, but our markets are over-indexed to premium markets and
segments, such as the distributed generation segment which accounted for 54% of our total shipments in 2020. This was significantly higher than the share of the distributed generation segment overall,
which accounted for 38% of the global market. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our
Global Energy segment primarily comprises solar power project development and sale, solar power projects operation and sales of electricity globally outside of China, and our CSI
Solar segment comprises solar power project development and sale, solar power projects operation, and sale of electricity in China. While we plan to continue to monetize our current portfolio of solar

Solar is one of the first movers in developing and supplying energy storage solutions and projects. Given the exponential market opportunities driven by rapid technology
improvements, declining battery storage costs, rising penetration of renewable energy and accelerating retirements of fossil fuel capacity, we have been developing our technology and expertise in
battery storage solutions over the past few years, strategically positioned the Company both in solar plus battery storage as well as in stand-alone storage opportunities. We have a unique advantage
in tapping into the large energy storage market opportunities given our strong position as a global leader both in module manufacturing as well as a solar project development. Thus, both the CSI Solar
and Global Energy segments have focused strategically on their respective energy storage businesses. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
battery storage system integration team, currently under CSI Solar, focuses on delivering bankable, end-to-end, integrated battery storage solutions for utility scale, commercial and
industrial, as well as residential applications. These systems solutions will be complemented with long-term service agreements, including future battery capacity augmentation services. In this
business, we had 861 MWh of battery storage projects contracted or under construction, 1.4 GWh in high probability forecast and 4.8 GWh of early- to mid-stage pipeline as of March&nbsp;31, 2021. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
energy storage project development team, currently under Global Energy, is now fully integrated within the main solar development team, building our pipeline of utility-scale energy
storage projects, both co-located with solar PV as well as stand-alone opportunities. In this business, we had 3&nbsp;MWh of battery storage projects in operation, 1.2&nbsp;GWh in construction,
1.1&nbsp;GWh of backlog and 14.6&nbsp;GWh of early-to mid-stage pipeline as of March&nbsp;31, 2021. </FONT></P>

addition, the securities market has from time to time experienced significant price and volume fluctuations that are not related to the operating performance of particular companies.
These market fluctuations may also have a material and adverse effect on the price of our common shares. Particularly, concerns over economic slowdown resulting from the COVID-19 pandemics have
triggered a U.S. key market-wide circuit breaker for several times since March&nbsp;9, 2020, leading to a historic drop for the U.S. capital market. No guarantee can be given on how the capital
markets will react even
though actions have been taken worldwide to combat the spread of the COVID-19. These market fluctuations may also have a material adverse effect on the market price of our common shares. In the past,
following periods of volatility in the market price of their stock, many companies have been the subject of securities class action litigation. If we become involved in similar securities class action
litigation in the future, it could result in substantial costs and diversion of our management's attention and resources and could harm our stock price, business, prospects, financial condition and

Techniques employed by short sellers may drive down the market price of the common shares.  </I></B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Short selling is the practice of selling securities that a seller does not own but rather has borrowed from a third party with the intention of
buying identical securities back at a later date to return to the lender. Short sellers hope to profit from a decline in the value of the securities between the sale of the borrowed securities and the
purchase of the replacement shares, as short sellers expect to pay less in that purchase than they received in the sale. As it is in short sellers' interest for the price of the security to decline,
many short sellers publish, or arrange for the publication of, negative opinions and allegations regarding the relevant issuer and its business prospects in order to create negative market momentum
and generate profits for themselves after selling a security short. These short attacks have, in the past, led to selling of shares in the market. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We
have been the subject of short selling, and it is not clear what long-term effect such negative publicity could have on us. We may also be subject to short seller attacks from time to
time in the future. If we were to become the subject of any unfavorable allegations, whether such allegations are proven to be true or untrue, we may have to expend a significant amount of resources
to investigate such allegations and/or defend ourselves. While we would strongly defend against any such short seller attacks, we may be constrained in the manner in which we can proceed against the
relevant short sellers by principles of freedom of speech, applicable state law or issues of commercial confidentiality. Such a situation could be costly and time-consuming, and could divert
management's attention from the day-to-day operations of our company. Even if such allegations are ultimately proven to be groundless, allegations against us could severely impact the market price of
our common shares and our business operations. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Because we qualify as a foreign private issuer under the Exchange Act, we are exempt from certain provisions of the securities rules and

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We
are required to file an annual report on Form&nbsp;20-F within four months of the end of each financial year. Press releases relating to financial results and material events will
also be furnished to the SEC on Form&nbsp;6-K. However, the information we are required to file with or furnish to the SEC will be less extensive and less timely compared to that required to be
filed with the SEC by U.S. domestic issuers. As a result, you may not be afforded the same protections or information that would be made available to you were you investing in a U.S. domestic issuer. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We may issue and sell shares of our common stock having aggregate sales proceeds of up to $150,000,000 from time to time. Because there is no
minimum offering amount required as a condition of this offering, the actual total public offering amount, commissions and proceeds to us, if any, are not determinable at this time. There can be no
assurance that we will sell any shares under, or fully utilize, the distribution agency agreement with the sales agent as a source of financing. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We
currently intend to use the net proceeds from this offering to further enhance our ability to execute our long-term strategic growth plans, including investing in our battery storage
business and growing our storage pipeline. We may also use a portion of net proceeds to invest in or acquire businesses, assets or technologies that we believe are complementary to our business,
including investments to strengthen our portfolio of stable, cash-yielding solar power projects that we have developed and are expected to be monetized through public vehicles in markets such as
Brazil and Europe. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
expected use of the net proceeds from the sale of common stock offered by this prospectus supplement represents our intentions based upon our current plans and business conditions.
The amounts and timing of our actual expenditures may vary significantly depending on numerous factors and, as a result, our management will retain broad discretion over the allocation of the net
proceeds from this offering. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Sales of our common shares under this prospectus supplement and the accompanying prospectus may be made in sales deemed to be "at-the-market
offerings" as defined in Rule&nbsp;415 promulgated under the Securities Act of 1933, as amended, including by means of ordinary brokers' transactions on or through the Nasdaq Global Select Market or
other markets for our common shares, sales made to or through a market maker other than on an exchange or otherwise in negotiated transactions at market prices prevailing at the time of sale or at
negotiated prices, or as otherwise agreed with the sales agents. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Upon
written instruction from us, US Tiger Securities,&nbsp;Inc., as sales agent, will use its reasonable efforts to sell on our behalf, as our agent, the common shares offered hereby
as agreed upon by us and the sales agent. We will designate the maximum amount of common shares to be sold through the sales agent, on a daily basis or otherwise as we and the sales agent agree.
Subject to the terms and conditions of the distribution agency agreement, the sales agent will use its reasonable efforts to sell, as
our sales agent and on our behalf, all of the designated common shares. We may instruct the sales agent not to sell common shares if the sales cannot be effected at or above the price designated by us
in any such instruction. We may suspend the offering of common shares under the distribution agency agreement by notifying the sales agent. Likewise, the sales agent may suspend the offering of common
shares under the distribution agency agreement by notifying us of such suspension. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
sales agent will provide written confirmation to us following the close of trading on the Nasdaq Global Select Market each day on which our common shares are sold under the
distribution agency agreement. Each confirmation will include the number of common shares sold on that day, the gross sales price per share and the compensation payable by us to the sales agent in
connection with the sales. We will report at least quarterly the number of common shares sold through the sales agent under the distribution agency agreement, the proceeds to us (before expenses) and
the compensation paid by us to the sales agent in connection with the sales of the common shares. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We
will pay the sales agent compensation for its sale of common shares as follows: (a) if the gross sales price of the common shares sold pursuant to the distribution agency agreement
(before expenses) of the offering equals $150 million or more, the sales agent shall be paid $500,000 in total compensation; and (b) if the gross sales price of the common shares sold pursuant to the
distribution agency agreement is less than $150 million, the sales agent shall be paid $200,000 in total compensation. Our net proceeds from the offering of shares hereunder will equal the gross
proceeds, less the sales agent's commission less any expenses payable by us and any transaction fees imposed by any governmental or self-regulatory organization in connection with the sales. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Settlement
for sales of common shares will occur on the third business day following the date on which any sales were made in return for payment of the net proceeds to us. There is no
arrangement for funds to be received in an escrow, trust or similar arrangement. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Under
the terms of the distribution agency agreement, we also may sell shares to US Tiger Securities,&nbsp;Inc. as principal for its own account at a price agreed upon at the time of
sale. If we sell shares to US Tiger Securities,&nbsp;Inc. as principal, we will enter into a separate agreement setting forth the terms of such transaction, and we will describe this agreement in a
separate prospectus supplement or pricing supplement. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In
connection with the sale of the common shares on our behalf, US Tiger Securities,&nbsp;Inc. may be deemed to be an "underwriter" within the meaning of the Securities Act of 1933, as
amended, and the compensation paid to it may be deemed to be underwriting commissions or discounts. We have agreed to provide indemnification and contribution to US Tiger Securities,&nbsp;Inc.
against certain civil liabilities, including liabilities under the Securities Act of 1933, as amended. </FONT></P>

prospectus is part of an "automatic shelf" registration statement that we filed with the United States Securities and Exchange Commission, or the SEC, as a "well-known seasoned
issuer" as defined in Rule&nbsp;405 under the Securities Act of 1933, as amended, or the Securities Act, using a "shelf" registration process. By using a shelf registration statement, we or any
selling shareholders may sell our
shares, preferred shares and warrants or any combination of any of the foregoing from time to time in one or more offerings on a continuous or delayed basis. This prospectus only provides you with a
summary description of these securities. Each time we or any selling shareholders sell the securities, we will provide a supplement to this prospectus that contains specific information about the
securities being offered and the specific terms of that offering. The supplement may also add, update or change information contained in this prospectus. If there is any inconsistency between the
information in this prospectus and any prospectus supplement, you should rely on the prospectus supplement. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;You
should rely only on the information contained or incorporated by reference in this prospectus and in any prospectus supplement. We have not authorized any other person to provide you
with different information. If anyone provides you with different or inconsistent information, you should not rely on it. We will not make an offer to sell the securities in any jurisdiction where the
offer or sale is not permitted. You should assume that the information appearing in this prospectus and the applicable supplement to this prospectus is accurate as of the date on its respective cover,
and that any information incorporated by reference is accurate only as of the date of the document incorporated by reference, unless we indicate otherwise. Our business, financial condition, results
of operations and prospects may have changed since those dates. </FONT></P>

by referring you to those documents. Each document incorporated by reference is current only as of the date of such document, and the incorporation by reference of such documents shall not create any
implication that there has been no change in our affairs since the date thereof or that the information contained therein is current as of any time subsequent to its date. The information incorporated
by reference is considered to be a part of this prospectus and should be read with the same care. When we update the information contained in documents that have been incorporated by reference by
making future filings with the SEC, the information incorporated by reference in this prospectus is considered to be automatically updated and superseded. In other words, in the case of a conflict or
inconsistency between information contained in this prospectus and information incorporated by reference into this prospectus, you should rely on the information contained in the document that was

transactions and events described in this prospectus or in any prospectus supplement will happen as described or that they will happen at all. You should read this prospectus and any accompanying
prospectus supplement completely and with the understanding that actual future results may be materially different from what we expect. The forward-looking statements made in this prospectus and any
accompanying prospectus supplement relate only to events as of the date on which the statements are made. We undertake no obligation, beyond that required by law, to update any forward-looking
statement to reflect events or circumstances after the date on which the statement is made, even though our situation may change in the future. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Whether
actual results will conform to our expectations and predictions is subject to a number of risks and uncertainties, many of which are beyond our control, and reflect future
business decisions that are subject to change. Some of the assumptions, future results and levels of performance expressed or implied in the forward-looking statements we make inevitably will not
materialize, and unanticipated events may occur which will affect our results. The "Risk Factors" section of this prospectus directs you to a description of the principal contingencies and
uncertainties to which we believe we are subject. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;This
prospectus also contains or incorporates by reference data related to the solar power market in several countries, including China. These market data, including industry demand and
product pricing, include projections that are based on a number of assumptions. Demand for solar generated electricity may not ultimately increase at the rates expected, or at all. The failure of the
market to grow at the projected rates may materially and adversely affect our business and the market price of our securities. In addition, the rapidly changing nature of the solar power market and
related regulatory regimes subjects any projections or estimates relating to the growth prospects or future condition of our market to significant uncertainties. If any one or more of the assumptions
underlying the market data proves to be incorrect, actual results may differ from the projections based on these assumptions. You should not place undue reliance on these forward-looking statements. </FONT></P>

Overview  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We are one of the world's largest solar power companies and a leading vertically-integrated provider of solar power products, services and
system solutions with operations in North America, South America, Europe, South Africa, the Middle East, Australia and Asia. We are continued in British Columbia, Canada, and conduct most of our
manufacturing operations in China and Southeast Asia. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our
business consists of the following two business segments: CSI Solar segment and Global Energy segment. Our CSI Solar Segment involves the design, development, manufacturing and sale
of a wide range of solar power products, including solar modules, solar system kits, battery energy storage solutions, China energy (including solar projects, EPC services and electricity revenue in
China), and other materials, components and services (including EPC). Our Global Energy Segment primarily consists of global solar and energy storage power projects (excluding China), O&amp;M and asset
management services, global electricity revenue (excluding China), as well as other development services. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Under
our CSI Solar business segment, we design, develop and manufacture solar ingots, wafers, cells, modules and other solar power products. Our solar power products include standard
solar modules and specialty solar products. Our products include a range of solar modules built to general specifications for use in a wide range of residential, commercial and industrial solar power
generation systems. Specialty solar products consist of customized solar modules that our customers incorporate into their own products and complete specialty products, such as portable solar home
systems. We employ a flexible, vertically integrated business model that combines internal manufacturing capacity with direct material purchases of both cells and wafers. We believe this approach has
benefited us by lowering the cost of materials of our solar module products. We also believe that this approach provides us with greater flexibility to respond to short-term demand increases. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our
competitive advantage is driven by our strong brand, defined as being rated the number one "most bankable brand" by Bloomberg New Energy Finance over the past four consecutive annual
bankability surveys. We also have one of the most globally diverse end markets, shipping to over 70 countries on an average quarter, including the U.S., Japan, China, Vietnam, Brazil, Spain,
Australia, Germany, Mexico, Canada and the Netherlands. Our customers are primarily distributors, system integrators, project developers and installers/EPC companies, but our markets are over-indexed
to premium markets and segments, such as the distributed generation segment which accounted for 54% of our total shipments in 2020. This was significantly higher than the share of the distributed
generation segment overall, which accounted for 38% of the global market. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our
Global Energy segment primarily comprises solar power project development and sale, solar power projects operation and sales of electricity globally outside of China, and our CSI
Solar segment comprises solar power project development and sale, solar power projects operation, and sale of electricity in China. While we plan to continue to monetize our current portfolio of solar
power projects in operation, we also intend to grow our energy business by expanding our project pipeline. In March 2015, we acquired Recurrent Energy,&nbsp;LLC, or Recurrent, a leading solar energy
developer with solar power projects located principally in California and Texas, and thereby significantly increased our solar project pipeline. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In
October 2017, our Japanese subsidiary sponsored the listing of the Canadian Solar Infrastructure Fund on the Tokyo Stock Exchange. It currently remains as the largest publicly listed
solar infrastructure fund in Japan, which is one of our key markets. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;As
of March&nbsp;31, 2021, our project backlog (formerly called late-stage, utility-scale, solar project pipeline), which refers to projects that have passed their Risk Cliff Date and
are expected to be built in the next one to four years, totaled approximately 3.7&nbsp;gigawatt peak, or GWp, with 744&nbsp;megawatt peak, </FONT></P>

Solar is one of the first movers in developing and supplying energy storage solutions and projects. Given the exponential market opportunities driven by rapid technology
improvements, declining battery storage costs, rising penetration of renewable energy and accelerating retirements of fossil fuel capacity, we have been developing our technology and expertise in
battery storage solutions over the past few years, strategically positioned the Company both in solar plus battery storage as well as in stand-alone storage opportunities. We have a unique advantage
in tapping into the large energy storage market opportunities given our strong position as a global leader both in module manufacturing as well as a solar project development. Thus, both the CSI Solar
and Global Energy segments have focused strategically on their respective energy storage businesses. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
battery storage system integration team, currently under CSI Solar, focuses on delivering bankable, end-to-end, integrated battery storage solutions for utility scale, commercial and
industrial, as well as residential applications. These systems solutions will be complemented with long-term service agreements, including future battery capacity augmentation services. In this
business, we had 861 MWh of battery storage projects contracted or under construction, 1.4&nbsp;GWh in high probability forecast and 4.8&nbsp;GWh of early- to mid-stage pipeline as of
March&nbsp;31, 2021. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
energy storage project development team, currently under Global Energy, is now fully integrated within the main solar development team, building our pipeline of utility-scale energy
storage projects, both co-located with solar PV as well as stand-alone opportunities. In this business, we had 3&nbsp;MWh of battery storage projects in operation, 1.2&nbsp;GWh in construction,
1.1&nbsp;GWh of backlog and 14.6&nbsp;GWh of early- to mid-stage pipeline as of March&nbsp;31, 2021. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We were incorporated under the laws of the Province of Ontario, Canada in October 2001. We changed our jurisdiction by continuing under the </FONT> <FONT SIZE=2><I>Canada Business
Corporations Act</I></FONT><FONT SIZE=2>, in June 2006. In July 2020, we filed articles of continuance, or the articles, to change our jurisdiction from the
federal jurisdiction of Canada to the provincial jurisdiction of the Province of British Columbia under the </FONT><FONT SIZE=2><I>Business Corporations Act</I></FONT><FONT SIZE=2> (British

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Most
of our directors and officers and some of the experts named in this prospectus reside principally outside the United States. Because these persons are located outside the United
States, it may not be possible for you to effect service of process within the United States upon those persons. Furthermore, it may not be possible for you to enforce against us or them, in the
United States, judgments obtained in U.S. courts, because all or a substantial portion of our assets and the assets of those persons are located outside the United States. We have been advised by
WeirFoulds&nbsp;LLP, our Canadian counsel, that there are defenses that can be raised to the enforceability, in original actions in Canadian courts, of liabilities based upon the U.S. federal
securities laws and to the enforceability in Canadian courts of judgments of U.S. courts obtained in actions based upon the civil liability provisions of U.S. federal securities laws, such that the
enforcement in Canada of such liabilities and judgments is not certain. Therefore, it may not be possible to enforce in Canada those actions against us, our directors and officers or the experts named
in this prospectus. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our
constituent documents do not contain provisions requiring that disputes, including those arising under the securities laws of the United States, between us, our officers, directors
and shareholders, be arbitrated.A significant portion of our current operations are conducted in China, and a significant portion of our assets are located in China. A majority of our directors and
officers are nationals or residents of jurisdictions other than the United States, and a substantial portion of their assets are located outside the United States. As a result, it may be difficult for
a shareholder to effect service of process within the United States upon us or such persons, or to enforce against us or them judgments obtained in United States courts, including judgments predicated
upon the civil liability provisions of the securities laws of the United States or any state in the United States. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Zhong
Lun Law Firm has advised us further that the recognition and enforcement of foreign civil judgments are provided for under the PRC Civil Procedures Law. PRC courts may recognize
and enforce foreign civil judgments in accordance with the requirements of the PRC Civil Procedures Law based either on treaties or arrangements between the PRC and the country where the judgment is
made or on reciprocity between jurisdictions, among others. Currently, China does not have any treaties or other arrangements that provide for the reciprocal recognition and enforcement of foreign
civil judgments with the United States or Canada. As a result, it is generally difficult to recognize and enforce in China a civil judgment rendered by a court in either of these two jurisdictions. </FONT></P>

out of any class or series of shares, an alteration of the special rights and restrictions attached to issued shares or the continuance of the corporation out of the jurisdiction of the BCBCA, require
a resolution of the type specified in the articles. Accordingly, if the articles fail to specify the type of resolution or, if the articles do not contain such a provision, a special resolution passed
by at least two-thirds of the votes cast by shareholders on the resolution. Other fundamental changes such as a proposed amalgamation or arrangement require a similar special resolution passed by the

amounts paid in settlement of, a proceeding in which any such director, officer or other individual, by reason of him or her being or having been a director of officer of, or holding or having held a
position equivalent to that of a director or officer of, our company or an associated corporation (a)&nbsp;is or may be joined as a party, or (b)&nbsp;is or may be liable for or in respect of a
judgment, penalty or fine in, or expenses related to, the proceeding. In addition we may, after the final disposition of any such proceeding, pay the expenses actually and reasonably incurred by any
such director, officer or other individual in respect of that proceeding, or in certain circumstances we may pay such expenses as they are incurred. However, Division 5 of Part&nbsp;5 of the BCBCA
also provides that we must not provide such indemnification or payment of expenses in certain circumstances including if, in relation to the subject matter of the proceeding, such director, officer or
other individual did not act honestly and in good faith with a view to our best interests, or, as the case may be, to the best interests of the associated corporation, and if, in the case of a
proceeding other than a civil proceeding, such director, officer or other individual did not have reasonable grounds for believing that his or her conduct was lawful. </FONT></P>

subject to the BCBCA, generally a director or senior officer of the company is liable to account to the company for any profit that accrues to him or her under or as a result of a contract or
transaction in which he or she holds a disclosable interest. However in certain circumstances a director or senior officer of the company will not be liable to account for and may retain any such
profit including if the contract or transaction is approved by the directors after the nature and extent of the disclosable interest has been disclosed to the directors, or if the contract or
transaction is approved by a special resolution of the shareholders after the nature and extent of the disclosable interest has been disclosed to the shareholders entitled to vote on that resolution.

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our board of directors has the authority, without shareholder approval, to issue an unlimited number of preferred shares in one or more series.
Our board of directors may establish the number of shares to be included in each such series and may set the designations, preferences, powers and other rights of the shares of a series of preferred
shares. Accordingly, our board of directors is empowered, without shareholder approval, to issue preferred shares with dividend, liquidation, conversion, redemption, voting or other rights which could
adversely affect the voting power or other rights of the holders of common shares. The preferred shares could be utilized as a method of discouraging, delaying or preventing a change in control of
Canadian Solar. Although we do not currently intend to issue any preferred shares, we cannot assure you that we will not do so in the future. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;As

Unless otherwise specified in connection with a particular offering of securities, any such agent will be acting on a best efforts basis for the period of its appointment. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;As
one of the means of direct issuance of offered securities, we may utilize the services of an entity through which it may conduct an electronic "dutch auction" or similar offering of
the offered securities among potential purchasers who are eligible to participate in the auction or offering of such offered securities, if so described in the applicable prospectus supplement. </FONT></P>

Delayed Delivery Contracts  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;If the applicable prospectus supplement indicates, we may authorize agents, underwriters or dealers to solicit offers from certain types of
institutions to purchase securities at the public offering price under delayed delivery contracts. These contracts would provide for payment and delivery on a specified date in the future. The
contracts would be subject only to those conditions described in the prospectus supplement. The applicable prospectus supplement will describe the commission payable for solicitation of those
contracts. </FONT></P>

Market Making, Stabilization and Other Transactions  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Unless the applicable prospectus supplement states otherwise, each series of offered securities will be a new issue and will have no established
trading market. We may elect to list any series of offered securities on an exchange. Any underwriters that we use in the sale of offered securities may make a market in such securities, but may
discontinue such market making at any time without notice. Therefore, we cannot assure you that the securities will have a liquid trading market. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Any
underwriter may also engage in stabilizing transactions, syndicate covering transactions and penalty bids in accordance with Rule&nbsp;104 under the Exchange Act. Stabilizing
transactions involve bids to
purchase the underlying security in the open market for the purpose of pegging, fixing or maintaining the price of the securities. Syndicate covering transactions involve purchases of the securities
in the open market after the distribution has been completed in order to cover syndicate short positions. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Penalty
bids permit the underwriters to reclaim a selling concession from a syndicate member when the securities originally sold by the syndicate member are purchased in a syndicate
covering transaction to cover syndicate short positions. Stabilizing transactions, syndicate covering transactions and penalty bids may cause the price of the securities to be higher than it would be
in the absence of the transactions. The underwriters may, if they commence these transactions, discontinue them at any time. </FONT></P>

Derivative Transactions and Hedging  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We and the underwriters may engage in derivative transactions involving the securities. These derivatives may consist of short sale transactions

underwriters may effect the derivative transactions through sales of the securities to the public, including short sales, or by lending the securities in order to facilitate short sale transactions by
others. The underwriters may also use the securities purchased or borrowed from us or others (or, in the case of derivatives, securities received from us in settlement of those derivatives) to
directly or indirectly settle sales of the securities or close out any related open borrowings of the securities. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Except
for securities issued upon a reopening of a previous series, each series of offered securities will be a new issue of securities and will have no established trading market. Any
underwriters to whom offered securities are sold for public offering and sale may make a market in such offered securities, but such underwriters will not be obligated to do so and may discontinue any
market making at any time without notice. The offered securities may or may not be listed on a securities exchange. No assurance can be given that there will be a market for the offered securities. </FONT></P>
