hey, they're Canadians, the only disputes they get in are over the shape on their bacon.
Jokes like that about Canadians not getting into fights are funny but also sad. The country has experienced huge growth recently driven by immigration from all parts of the world. Those people bring with them whatever cultural tendencies that had in their places of origin. And that includes violence, quick tempers, fighting, etc. Things normally not what you'd expect from Canadians.
There are already enclaves of people who moved en masse from home country to Canada where they live just as they did before, complete with their own codes of justice and morality which mean more to them than provincial law.
Some of it is muted by exposure and blending to the overall culture, it is true. But It's also safe to say Canada will continue to slowly be less and less "Canada" and more just a melting pot more like the US. There is no way to stop this short of ceasing the immigration options.
So enjoy making jokes while you can. Assuredly somewhere in Canada somebody will soon enough cut off their child's head for something on religious grounds, and others will obtain guns under hunting laws and instead use them on people.
Noting: I am USAmerican. But I work for Canadian company, which has nearly all immigrant employees in our Toronto headquarters. These are people who have nothing to do with Canada in any way, except that they happen to live there now instead of some place you see on the "tragedy today in..." news stories from some country overseas. They do not share any of the laid-back traits Canada is famous for. At all.
I also completely get that modern Canada was created in the first place by immigrants who displaced the "first peoples" much as the Indians were displaced in the US. I get that Canada wouldn't be Canada without ships full of people moving in. However, in the old days, you moved to a new country and eventually blended in for the good of all and because you had no choice. Your shared DNA made all strong. Nowadays you can move in and watch the same TV you had at home, and never integrate into anything new. Instead of making all stronger, this makes pockets of infection increasingly at odds with the body.
This same thing is happening in the US, of course. We're just used to it here. We happily kill each other and think nothing of it. I fear for Canada. This hasn't been their norm, but it will be.
