Certain things like non-emergency (but important) surgeries could take longer to schedule in Canada.

Yeah, hip replacements and that sort of thing have a months-long or even years-long waiting list. But, most people waiting for those things can still live pretty much normal lives. IMO the wait is too long. But, people can get by walking with a limp until their turn comes up.

If the trade-off to get treated more quickly for that sort of thing is to accept the for-profit medical system of the USA, there are virtually no Canadians who would accept that deal.
