[a-priori]

Canada has never had a united identity. It has always been fractured between English Canada and French Canada. That's an unstable arrangement, with two opposing poles of cultural power, and it's actually remarkable we have never gone to civil war over that divide.

Transitioning from a bi-cultural society to a multi-cultural society is actually an improvement, because it reduces the power of English and French cultures to simply strong minorities among many. It's resulted in a balance-of-power arrangement, where neither has any hope any longer of dominating the whole of Canada.

It means it's unlikely that either English Canada or French Canada will try to go to civil war with the other, because they have nothing to gain and everything to lose. That's a remarkable achievement all on its own.
