Attention: Mr. H. Christopher Owings, Assistant Director
 
Dear Mr. Owings:
 
Re:      TransCanada Corporation
Annual Report on Form 40-F for Fiscal Year Ended December 31, 2008
Filed February 25, 2009
File No. 001-31690
 
We received your letter dated June 25, 2009 with respect to TransCanada Corporation’s Annual Report filed on Form 40-F as noted above.  In response to your comment regarding the certifications filed as Exhibits 31.1 and 31.2, you will note that the instruction in paragraph 1 of the certification refers to the document as “annual report” as do our filed certifications and that the instruction on paragraph 2 does not refer to “issuer” or “registrant”, nor do the filed certifications.
 
With respect to the other noted discrepancies between the Form 40-F General Instructions and the filed certifications, we will ensure that all future filings contain language identical to the language included in the General Instructions, where required.
 
We acknowledge that:
 
·  
The Company is responsible for the adequacy and accuracy of the disclosure in the filings;
·  
Staff comments or changes to disclosure in response to staff comments do not foreclose the Commission from taking any action with respect to the filings; and
·  
The Company may not assert staff comments as a defense in any proceeding initiated by the Commission or any person under the federal securities laws of the United States.
 
We appreciate your attention to this matter.  Should you require anything further in this regard, please contact me at 403.920.7685.
 
Sincerely,
 
/s/ Donald J. DeGrandis
 
Donald J. DeGrandis
Corporate Secretary
