Stereotypes are fun.
Ask me about Canada, I'll tell you they ride moose, play hockey and apologize a lot (which, is not really a bad stereotype to have- being polite)
Ask me about France, I'll probably say that they surrender a lot and love cheese and wine (despite them having one of the most impressive military histories of any country in the world)
Ask me about the United States of America (my own country), I'll tell you its just a bunch of Bible thumping, burger guzzling, hummer driving, politically ignorant cowboys (even though I know a lot of really good people here).
Do I believe these stereotypes? Of course not. However, its just a bit of universal humor that has developed and is part of the culture. As long as you don't use stereotypes in a serious or hateful manner, and you can laugh at the stereotypes of yourself as well as those of others its fine.
edit-
Also, there is a chance that I may be moving to Canada sometime in my life. While the hockey nut and moose rider stereotypes are off, in my experience Canadians are actually quite nice and it seems like it would be a great place to live.
