Really? Nothing that's distinctly Canadian? Did you see the closing ceremonies for the Vancouver Olympics? My wife and I watched both the Canadian and American coverage. The announcer on the Canadian coverage was happily chatting away about the festivities, whereas the American announcer was pretty much speechless, because what he was seeing was so not American.
We're a hell of a lot friendlier and more polite than Americans, in general. Not that there aren't exceptions; there certainly are. But on the whole, it's true. I've traveled a fair amount through Canada, various parts of the US, and some in Europe. I've never felt uncomfortable or out of place, except in the US. Now, that was mostly in the north east, as when I went through Tennessee, people were almost as friendly as Canadians. Americans just seem to be more blunt and "in your face" than pretty much anybody else I've encountered in my travels.
Besides: we have Red Green.
