In most countries, the cost of such operations are fixed by the state (ex: Canada).

What do you mean? There are so many factors that could explain higher healthcare costs, including an aging population, or better health coverage.
I'm also not sure what it means for healthcare to be affordable. In most countries, the cost seems proportional to the general wealth. The US might be the exception, since it's one of the few countries with great wealth disparity and with a non-universal system (more bureaucratic overhead/costs).
