Canada appears to be much more fiscally responsible than the US and Europe so they will not be as bad off. This comes from all that I have read and my Canadian friends.
As I recall the US is Canada's #1 trading partner so they will be hurting. Additionally Canada benefited greatly from the oil boom and will be hurt from the massive drop.
I have thought a lot about depositing most of my money in Canadian banks but they currency fluctuation with oil make it problematic.
