Canada

Then you must hate our current universal healthcare as it is "for-profit". No one in the system is providing their services for free, they're paid by the Provincial Government (or in some cases the Federal government, like indigenous communities, military, etc). Some Doctors work as T4 employees, but the vast majority are in private practice where they bill the government for services rendered and operate as businesses. If the market demanded services at the boarder, businesses would be willing to provided their services without the government paying for infrastructure. Actually, I am currently seeing a specialist in a boarder city and the clinic advertises to Americans. They're more than happy to serve Canadians and bill the province, and the service has been exceptional.

I suspect your contentions with "for-profit" healthcare is the American system where regulation is minimal and the government isn't tasked with ensuring everyone gets healthcare? In Canada, for those without provincial healthcare, the provinces do have oversight on reasonable expenses .
