I don’t know about that… In my family of Canadians there was always a little bit of anti-American sentiment growing up. Culturally, while close, there are definitely differences. They used to come up during salmon season and cheat the system by catching over the limit and canning it at night so the authorities couldn’t count their catch. I would never say that all Americans are bad people, but the ‘fuck you, I got mine’ attitude seems to be much more prevalent south of the border.
