Canada only has a handfull of banks.

TD - Toronto Dominion (I think)
BMO - Bank of Montreal
RBC - Royal Bank of Canada
Banque National
Caisse Desjardins
Banque Laurencienne

perhaps some others, I just listed the ones that are popular in Quebec/Montreal

I personally exclussively deal with TD only and have never had an issue... granted I am one of the smallest of small fries in the bitcoin world... just direct depositing miniscule amounts of cash from cavirtex.
