I've often wondered if we could open up private clinics in Canada for Americans where we charge reasonable rates. Kind of start a medical tourism industry by the border.
Thailand has a fairly large medical tourism industry - a number of hospitals in Bangkok are considered world-class (if not world-leading). I know a few people who just go there once a year for a weekend for their annual check-up, since the difference in price from doing it in a decent private hospital in Hong Kong can cover the cost of flights and accommodation, plus you get a weekend in Bangkok which is nice...
While many would not be able to afford a trip to Canada, I would think there would still be a sizeable number who live within 1-2h from the border who could drive there for non-emergency care.
