Coverage is rationed in Canada all the time. Because socliaized medicine in Canada is a Holy Grail of "Canadian Identity" and "Canadian Values" (ie leftwing values pushed by the elites) it doesn't get coverage.

"The province of Ontario’s move to reduce costs by expanding domestic capacity to perform bariatric surgery is raising concerns about longer waiting lists and regional variations in the availability of surgery.

The move could also jeopardize the lives of morbidly obese patients, charges Dr. Yoni Freedhoff, director of the Bariatric Medical Institute, a privately-run weight management centre in Ottawa, Ontario.

“People do die on wait lists. This is a sick population,” he says. “This isn’t somebody who needs a hip or a knee. This is someone whose medical condition is serious enough that it can cause permanent damage and/or death while they’re waiting.”"
