Edit: just saw an earlier better comment saying the same thing: https://news.ycombinator.com/item?id=45737190

Countries with “free” also healthcare ration it and don’t cover everything.

Socialized insurance is still insurance, and at least in Canada it’s the only game in town, so if you have a procedure that is denied or not available your choice is basically to go to the US and pay for it and be in the same position as an uninsured American.
