What Makes Canadians Different from Americans?

I recently facilitated a session in the States and within a few minutes I heard someone's muttered question: "Is this guy from Canada?" When I asked what gave it away (not that I was trying to hide our country of origin), people answered that it was how I say words like "process" and "organization". Fair enough.

But, aside from the proper way in which we speak, what are the less obvious give-aways about where we're from? I can think of a few:

• For us, "March Madness" refers to the late March snow fall that inevitably hits after we're sure we're done with the stuff. It most certainly does not refer to a tournament that highlights our top collegiate basketball talent. We'd have a tournament like that but all of our top talent is busy in March playing in another country's tournament (besides, we don't have enough for two teams).
• For us, the "right to bear arms" refers to July and August when we're able to wear short sleeves. (The American spelling of "bare" is different from ours).
• Speaking of spelling, we learn to spell in school. We don't just take the hard words and create easier ways to spell them. We also don't create new names for letters of the alphabet so that they rhyme better.
• In Canada, we use the Metric system. This puts us miles ahead of Americans.
• In Canada, we don't (yet) have metal detectors in all of our schools. We don't do that because all of the academic medals that our students wear would set off the detectors willy-nilly. 
• You see, in this country we value education and invest our hard-earned tax dollars ensuring that everyone has access to it (if you're having trouble with that last sentence, education = "edu-m'cation" in American). We could also have ensured that everyone has access to guns, but then we'd need metal detectors in our schools.
• Before we start being accused of Communism or Socialism, please understand that we do favour the rich when it comes to just about everything (including education). But they can't have guns. And (please sit down everyone) they pay higher taxes than other people.
• Speaking of taxes, we pay lots of them: Income Tax; Sales Tax; Goods and Services Tax. "Sin" taxes. Etc. Being a Canadian comes with a price which we obediently pay. That's because we have lots of Government. It generally keeps our cities clean, our streets moving, our people educated, and our health good. And what's best, we don't often have to bear arms to ensure that our Government behaves (our last rebellion was in 1837 and most of the rebels were drunk).
• In Canada we don't turn celebrities into Mayors. We turn Mayors into celebrities (at least in Toronto, and not the good kind of celebrities). 
• While we're on the celebrity front, Canadians are surprisingly prominent. Canadians are funny. They sing well. They are really good at hockey and a few are good at other sports. They are great at anchoring American news. Canadian actors are like comfort food - they bring calm and class to American tv and movies. We've actually started making (and watching?!?) some of our own tv and movies, and some of them look like modern film production equipment was used.
• We have health care.

I could go on and on blowing our horn, but that's very un-Canadian. In fact, we're more likely to be heard complaining about our lot in life up here in this cold and mostly empty country. There's a reason for that too, but I am sworn not to reveal it (by our Ministry of Minimal American Immigration).
