My childhood exposure of Canada was through the movie strange brew. Still a favorite of mine.

I figured all Canadians were hosers who scarfed donuts and drank beer.
Then I watched Kids In the Hall and I figured they were mostly funny gay fellows.
Then I watched South Park . . .
South Park is the most honest portrayal of Canada in the media today.
At worst in my childhood were maybe a McDonalds and a Dairy Queen. No cable TV and few other cultural influences.
Now we're fat, WalMart shopping, gun toting, rap music/urban culture, even dialects are more US sounding.
