I've definitely met some Canadians while travelling who have projected an aura of "hey, we're not Americans, aren't we great?"

Generally, Canadians abroad are pretty cool, as are most people I've met and taken the time to talk to. Most people.

As for Canadians at home, I have had a lot of interactions that reminded me of interactions I've had with citizens of other English speaking countries, who have expected to be familiar with some part of their foreign policy or political . . . stuff, not to mention pop-cultural stuff and when they understand that I am not familiar with whatever they are referencing, there's usually some mild surprise (sometimes shock) followed by a little, usually inaudible sigh, a slight eye-roll, etc.

I don't know if that's a function of more U.S. culture being piped in to other countries via media or of a culture-wide lack of interest in all the stuff from other English speaking countries. Maybe both.

Also, I believe that those little Canadian flag patches are available from Canadian consulates and embassies. I don't think that the U.S. consulates and embassies offer them. To be honest, I rarely inform the consulate or embassy that I'll be in a certain country.
