The reality with healthcare is that, unless you're in need of it, most people don't have direct experience with it to make any valid comments about the quality of health care. Better yet, most Americans have never accessed Canadian health care but are bombarded with the myths perpetuated in the media. And most Canadians have never accessed American health care and are bombared with... American media bombarding Americans with myths about Canadian health care. Most people are ignorant and don't have first hand experience, so they're just perpetuating myths based on things they've heard or read second hand.
All I know is that if I need healthcare, I walk down the block to the local walk-in clinic, I wait my turn (usually no longer than 30 minutes), I speak with the doctor, I get my prescription or test or whatever, I walk out. Presto.
What I also know is that access to health care and quality of health care depends on the kind of health care you need and where you are in the province. I'm very happy with the health care in Vancouver I've required. However, I've heard completely different stories from other parts of Canada. It really does vary. Since health care is funded provincially, it really depends where you are in this country.
