Americans stampede northward

For the first time in thirty years, Uncle Sam lost more than 10,000 of his children to the folks up north. The number of Americans emigrating to Canada has almost doubled since 2000, according to a report from the Association for Canadian Studies (pdf).

Although the Canadian study does not provide statistics about the emigrants' motivations, anecdotal evidence suggests that post-9/11 U.S. policies are a major drive for the move. Other reasons may include Canada's generous healthcare system and Canada's tolerance for gay marriage, as American emigrate Tom Kertes tells ABCNews.

Becoming a magnet for America's liberals, however, doesn't seem to be dampening anti-American feelings in Canada.
