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...

Would not help because many of those without insurance cannot afford a trip up to Canada. And secondly it will not help for emergency care.

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.

Comfy buses would be nice. Maybe some outpatient services where you recover at a local sporting event, fishing maybe....
