Can Canada be entirely seperate from the U.S.A., not a chance.
Our whole society is strongly intertwined with the U.S., economically, socially, technologically, etc, etc.
We must remember that Canada's economy is mainly still a resource based agricultural economy. We harvest resources and sell mainly to the U.S.A. (although we get ripped off for it). Look at the fallout from the cattle farmers up here when the U.S. banned live cattle.
We watch a lot of American made television and movies. We buy products from American companies who usually don't even make them in America.
Many people including myself feel we are far to attached to the U.S.A. for our own good. But, instead of working out how to keep America out, we must become more independent so that we can stand up on our own.
