There's certainly been plenty of competitive USA/Canada banter throughout these Winter Olympics - both on this site and in Vancouver. We Americans can point to the fact that we won 37 medals, the most by any country ever. Canada can point to their 14 golds, and say that while they might not have seen their dream of "Own the Podium" come true, they owned the top of the podium like no other country has before.
But rather than bicker about who was better, the more interesting thing is that North America as a whole (USA and Canada) dominated these Olympics in a way that suggests a major power shift in terms of Winter Olympic sports.
The United States and Canada won 63 combined medals. That's stunning. Take any other two major longtime Winter Olympic heavyweights, like Germany and Russia (45 combined medals), and you don't even come close. Hell, Germany and Norway (keep in mind people in Norway are born with skis on their feet) totaled only 53 combined.
So, when you get down to it, both the United States and Canada made massive strides in these Games. Canada won 14 golds after never having won gold on its home soil in the Winter Olympics. The USA won the 4-man bobsled gold, something that we hadn't done in 62 years. Canada won ice dancing gold, which has been owned by the Russians since time immemorial. An American man won men's figure skating. The list goes on.
The bottom line is both countries were extremely impressive, and it's clear that Europe is no longer the the sole major player in the Winter Olympics. North America has arrived.
