So now the truth comes out. That is the missing link. This was a hit piece.
Well, that's not the whole truth either. Canada's health care system emerged in phases, at the provincial level, starting back in 1946. The Hospital Insurance and Diagnostic Services Act was passed in 1957, with the national government picking up 50% of any hospital costs in any province that offered health insurance.
Yukon first had medicare in 1968-1969. It was probably not single payer at the time.
Canada only went to single payer after LARGE numbers of doctors started opting out. So many did this that the government passed legislation making it a federal crime for a doctor to receive direct payments for medical services. This had the effect of enslaving doctors. Today there are probably more canadian trained doctors in the US than here in Canada.
