All of the Canadians on this thread, er, live in the US, though? I'm not sure Billy Ray Cyrus could even find Canada on a map, so I think you're safe..
None of the Americans you listed do. I doubt they'd head North for financial gain.
Anyways, Canada is responsible for Hayden Christenwhatever. That annoying fuck who single handedly ruined Star Wars. Tough to top that pain...
