Most of what the OP says is simply untrue. The government does not employ everyone that works for the Canadian health care system. Doctors offices and clinics are all privately owned and operated, and many hospitals are private as well (for-profit and non-profit) The only real difference between the American and Canadian system is that the provincial governments act as the sole health insurance companies. Canada has private insurance companies too, but these provide for disability, death, dental, and out-of-hospital drug benefits.

It is true that some of these governments have decided not to cover certain procedures when other less-costly ones are available, and there are sometimes minor user-fees tacked on for certain things that are deemed not strictly "medical". However, the Canada Health Act insures that everyone is covered, anywhere in Canada, for all medical needs.

Personally I'd rather my government spend 40% of it's revenue on Health Care as opposed to military misadventures, pork spending, etc. Under single-payer, this money goes directly to the health and welfare of Canadian citizens and none is lost to a bloated private insurance bureaucracy, which makes it the kind of expenditure citizens ought to want more of.
