There is absolutely no comparing Canada's well financed banks and those in Europe. During the great recession only CIBC had any negative quarters and the rest of the banks continued to show a profit. I think CIBC had purchased  10 billion in US housing bonds and their insurer went bankrupt.
I held all 6 of these stocks through the whole mess (dividends in a drip)and came out of it far ahead. The price of the stock fell for a while but the dividend bought way more stock.
In my opinion the Canadian Banks are a buy.
