Item 8.01 Other Events

On May 23, 2008, the following individuals associated with Canadian Solar Inc. (the “Company”) entered into sales plan agreements (“10b5-1 Trading Plans”) authorizing their brokers to sell, subject to certain conditions, up to the following numbers of shares of the Company on their behalf over the following periods:

				Number of
Name		Office with Company		Shares				Sales Period
Dr. Shawn (Xiaohua) Qu		Chairman, President and Chief Executive Officer			500,000			June 16 to November 16, 2008
Genmao Chen		Director, Research and Development			16,019			July 17 to November 16, 2008

Lingjun Zhang		General Manager, CSI Cells Ltd.			18,931			July 20 to November 20, 2008

The 10b5-1 Trading Plans are intended to comply with Rule 10b5-1 (“Rule 10b5-1”) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and the Company’s insider trading policy. Rule 10b5-1 allows corporate insiders to establish prearranged written stock trading plans. These plans must be entered into in good faith at a time when the insiders are not aware of material, non-public information concerning the Company or its securities. Subsequent receipt by the insiders of material, non-public information concerning the Company or its securities will not prevent prearranged transactions under these plans from being executed. These plans allow insiders to achieve prudent and gradual asset diversification over time.

The shares of the Company that may be sold under the 10b5-1 Trading Plans will come from the current holdings of the individuals listed above or from Company share options exercised by them during the sales period. The individuals listed above will have no control over the timing of the share sales under their 10b5-1 Trading Plans.

The information in this Form 6-K is being furnished and shall not be deemed to be “filed” for the purposes of Section 18 of the Exchange Act or otherwise subject to the liabilities of that section. Furthermore, the information in this Form 6-K shall not be deemed to be incorporated by reference into any registration statement or other document pursuant to the Securities Act of 1933, as amended, unless such registration statement specifically references this Form 6-K.
