Americans and Canadians

Have you noticed how much Canadians insist on being different from Americans? Don't you think they are saying that and repeat it all the time just because in fact they are very similar?
Ask me, they are no different. The only part of Canada which may claim being different is Quebec. Common origin, language, geopolitical situation and very common economical interests have been important defining elements for shaping these two nations. As an imigrant I see no difference, as a matter of fact the differences between Canadians and Americans are not more than the local differences in U.S.A itself.
