As a Canadian, I doubt the part about our "net benefit". As extreme weather becomes more common, it will become less comfortable for everyone. Maybe Canadians will be better off than Mexicans, but the farther out from the Goldilocks zone we go, the worse it's going to be, globally.
As for countries, I have doubts they can ever achieve anything. Real change is done at the community level.
