No one has mentioned your neighbor to the north. I realise most everyone is biased to choose the country they are from.
I like the fact that I don't own a gun (or any other weapon/self defence) and don't need to.
We mainly use the metric system (just like the rest of the world)
I don't have to yell/get angry at someone when something goes wrong and needs to be fixed (several occasions with my car with more than one location).
People here are much more relaxed and easier to communicate with. That's why some US based companies rely on Canadians to provide their support.
BTW - It's going to be reaching 30°C tomorrow (86°F) here in Winnipeg.
