My brother (Australian) spent some time in Canada and was able to see a doctor straight away and really cheaply a bunch of times, and visited the hospital once with a nasty foot injury with no dramas. It seemed like a pretty good system.

I remember contrasting that with my US experience at the same time, where a 10 minute consult with a doctor cost 600USD. I had a really obvious ear infection, just needed some antibiotics, but he must have seen me as a cash-cow and ordered a ton of unrelated blood tests that were pointless since I was flying out the next day. I walked away feeling like I'd been scammed.

(In Australia a doctor's visit is under 30USD, blood tests don't cost much either)
