Ignoring for a second that this poll was posted purely in fun - Canada, like the United States, is such a diverse nation that one could never truly lump all "Canadians" together and talk about them as if they have one uniform personality.
Some of the best friends I've ever had have been Canadian. I've also met a few assholes from Canada. Kind of like everywhere else in the world.
That said, I think I have enough experience with Canada/Canadians to make some broader generalizations about the national character.... some of it positive, some critical:
1.) Canadians are more polite than Americans in general
2.) Nothing pisses a Canadian off more than if/when you tell them there are so few differences between Canada and the US, the countries are almost indistinguishable
3.) Point above is funny, because Canada IS very similar to the US. If you dropped me off in a random town in Canada with no map, I wouldn't be able to tell you if I were in Canada or a northern US state. They're identical. The way people behave is identical. Even the accents are closer than Canadians think.
4.) Due to points 2/3, a lot of Canadians develop a weird "little brother" complex when it comes to the US. On the one hand, we're the stick by which they measure themselves. And they compare themselves, almost obsessively, to America. On the other hand, some Canadians like to play up the minor differences between the countries and take a snobbish attitude about how those differences make them better.
5.) Canadians have a great sense of humor, and they're generally funnier than Americans. Many great comedians hail from Canada.
6.) Canadians are generally more humble than Americans
7.) Canadians are much more nationalistic than Americans
8.) Canada has better beer and cigarettes
9.) Canada used to have better weed but now that honor goes to Colorado
10.) Canadians are very good hosts and really want you to enjoy your visit to their country. The same is true for some Americans (in the south), but for the most part, Americans tend to ignore foreign visitors or just don't care very much what you think of the US.
All that said, I love Canada! Would go back, plan to go back many times.
