Health care is done by the Provinces in Canada, with transfers from the Federal Government to help out. The most recent Alberta budget[0] puts the cost of health care at about $20B. This represents approximately 40% of Alberta government spending.
Is that due to waste or inefficiencies? I honestly have no idea. I just know that it's a big number.
Another thing to keep in mind is that, at least in Canada, the government provides some base amount of health services, but there are still other things that aren't covered. In Alberta, someone might go to the ER for a severe asthma attack and that's covered, but the prescriptions to keep the asthma under control are paid for out of pocket or from a benefit plan (which could be an individual plan or through an employer). Similarly, dental is not covered, but may be covered under a benefit plan.

Then you have amortization of the equipment and operating room, and some fraction of the hospital support staff during the prep and recovery stages. But even with that I still don't see where the $80,000 for the surgery cost comes from.
