Actually, I think it's more because we-just-do-whatever-the-US-does most the time anyway. It's easier that way. Think of having a big brother... on steroids... who has temper tantrums if he doesn't get his own way. ...and your room is attached to his. Yeah... sometimes it's just easier to go along with things
I always thought the Canadians should split their part of the continent into three provinces, tell the Queen to go pound sand and apply for statehood. That would stop this subterfuge of independence and make the reality official.
You'd have to get rid of Quebec though. We have enough problems with the remnants of the french in Louisiana we don't need more to the north.
