Hey, maybe the US can just kinda expand north by default.

(I always thought of Canada as a northern suburb of the USA anyhow...)

The vast majority of Canadians are crowded as close to the warm border as they can get. Go into the interior a few miles [kilometers in Canadaspeak] and you rapidly run out of people. Would a population decrease mean much to Canada? The real question is, if everybody left Canada, how would you know outside the 100 southernmost miles?

Unfortunately, with Canada's refugee and immigration policies, it's starting to look like a cesspool of third-world castoffs. In a just a few decades, Canada will become a nation of itinerant Muslims, derelict Africans and a hodge-podge of Asian drifters.

That concept is working fine for Mexico.
