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?
