As another Canadian, it's annoying to have you link your ignorance to your nationality. I'm confident that the vast majority of Canadians know that a mile is, very roughly, around 50% longer than a kilometer.
And if you think the difference is miniscule in normal usage, you just try driving 59 MILES per hour on a city street with a 50km/h limit, and see how the cops feel about that. (I say 59 because my lived experience is that everyone drives 10 over, and the cops don't ticket at 9 over; your city may vary)
Or try estimating when you're going to arrive at a meeting that's 100 MILES away on the highway, when you think "oh, 100 km, I can go 110 on the highway, plus the time to get out the door, call it an hour".
Even at walking speeds, 2 miles of walking is going to feel different than 2 km of walking.
