Two of my best friends are Canadians and both of them are absolutely thrilled to point out that Canada has shows that go out of their way to find stupid Americans on the street and ask them questions for laughs. I've watched these shows personally every time I go up to Canada.
When I come home to California, I turn on the TV and never hear mention of Canadians except from conservative circles (who have a grudge against Canada because of their healthcare system and banking system actually... y'know... working.)
A Canadian comedian actually framed it well: America and Canada have a sibling rivalry and that's been long ago escalated into a personal rivalry. However, while Canada takes this rivalry rather seriously, America was never told.
I'm not saying that Canada's not represented comically in our media... I'm just saying it goes both ways and there's no "hatred" behind it. We're sibling countries, we mock each other, were there a geopolitical equivalent to a wedgie we'd be giving them to each other.
Though, one thing can be agreed on: Most people are annoyed by Quebec, this is true on both sides of the border (either you're part of the country or you're not, don't waffle)
