Aside from being a country (obviously) and
America's hat, Canada is a character from the
anime Hetalia. He has a pet polar bear that he can't remember the name of. (Its name is Kumajiro.) Everyone either confuses him for America, can't see him, or doesn't know who he is.
Kumajiro: Who are you?
Canada: I'm Canada.
-----
England: Hey, America, about those war plans...
Canada: Um, sorry, but I'm not America.
-----
Canada: *running into a G8 meeting* Sorry I'm late!
Japan: Oh, it's fine. We've...all been waiting for you...
Everyone: Who is this guy?
