BC is not an option.
If the frogs break away from Ottawa, the Atlantic provinces will be the ones who will be most likely to consider annexation by the U.S.
Mainly because they are such an economic basket case and rely heavily on Ottawa.
We do not really want the maritimes. We want the prairie provinces. What I guess might be an ideal (although not likely) solution: Quebec goes on its own. Maritimes, territories (Yukon, NWT, etc) and Ontario remain as Canada. And the western provinces join the US: Sask, Manitoba, Alberta and BC. Would that be a viable Canada? Or would Ontario go on its own, and kick out the maritimes? Also, doesn't northern Quebec have a bunch of Indians who don't want to be part of another country?
I would really be surprised if Quebec separates. Lots of immigrants in Quebec are making it less French. It probably couldn't win in a province-wide referendum.
