I think in this context the idea of open borders between the USA and Canada in a similar fashion to the EU would be an interesting thought experiment to study.

I think in this context the idea of open borders between the USA and Canada in a similar fashion to the EU would be an interesting thought experiment to study. Presumably a bunch of Canadians would leave Canada in favor of higher US salaries, or cheaper housing. The idea that Toronto real estate pricing is so geographically close to Buffalo, Cleveland, and Pittsburgh is interesting. Then again, presumably a bunch of people looking for affordable healthcare would be moving up to Canada. Or perhaps not all that many people would go anywhere permanently and they would just have an easier time going on vacation in either direction.
