@matttheroman,
You don't understand the situation in Quebec very well.
The native community has made it clear that if Quebec tries to secede from Canada, the native community will secede from Quebec and stay with Canada. The big Quebec money source is based on land controlled by the native community. Quebec will be broke in no time.
In any case, the separatist party collapsed in the federal election earlier this month.

Newfoundland and Labrador would seriously kick the U.S. in the teeth - there is no love for the U.S. there. They might go to Portugal, but the U.S. just isn't an option.
People in Alberta don't like U.S. style government.
The U.S. would end up with battles on 3 or more fronts - and they'd be financial battles, which the U.S. doesn't have the economic strength for. Chinese, Russian and Indian money would support Canada.
