Oh, one more thing: a common strategy for invaders is to let domestic rebellions happen, and then come in to "protect their rights". Hopefully CSIS and the Mounties can come down hard on any Canadian going on Fox News to invite invaders to come annex our country. It's a valid political position and thought experiment in peacetime; when there is a real possibility of a war, it's treason. Straight to jail! And definitely don't allow any kind of trucker convoy demonstrations in large numbers.
