Canadian gaap vs indian accounting standard

Hello Friends

I am a CA ( India) currently studying for my CPA final exams in Canada. I am wondering is there any published source of information which states the differences between Indian Accounting standards and Canadian GAAP. This is due to the fact, that i am fresh with Indian Standards and not Canadian GAAP. I have two alternatives. 

1) To Study Canadian Gaap from the scratch.

 or

2) Refresh Myself with Indian Accounting standards and just note the key differences between Indian Accounting Standards  and Canadian GAAP. 

Any help would be greatly appreciated. Thanks
