Well pretty much habitable land mass. But I also think Canada's export business isn't that great. I mean sure, fish, syrup, maybe some self sufficient factory goods, but I'd think they would need a lot of importing. Maybe I'm wrong though.
well technically there are a very few number of people that live in upper parts so i would consider it habitable but in itself the definition is debatable
i cant really talk about business up there because honestly i have zero idea, im american :P the same goes for america, though. we do waaaay more importing than exporting
