It would be cool if everyone knew what they were talking about.
The only huge flaw in the Canadian system that I know of is that any type of therapeutics for cancer or autoimmune disease, that can be in upwards of $50k for a full treatment, are not covered under their basic plan as opposed to something like a life saving heart procedure. Both are live saving, both are expensive, but because one is a drug it's not covered. In those instances the Canadian system is no better.
