The Canadian Banks such as Bank of Nova Scotia, operating in Argentina, have not lost any value on the Toronto stock market. I would guess they had transferred their money and that of the depositors out of the country.
Canada has mostly big international operators in banking; there are few small ones. Here in Alberta, I think the Alberta Treasury Bank (still government I think but on the way to privatization) is the only one.
The International Monetary Fund was a good idea, but as it stands, it reflects the interests of the larger industrial nations.
