It depends on whether you're talking what it costs you as an individual, what it costs for medications, for treatments, for O2. If you're talking about what it costs the health systems, they're very different. I know the US figures that it costs something like 3.9 billion (with a b) in lost work every year. Here's a link to an article published in a Canadian journal that may address your question:

I'm not sure it's really possible to compare because Canada has a national health system that varies by province in the way it's delivered and also allows for private pay, while we have a completely fractured system that doesn't really work very well for much of anyone, even if you do have insurance through work. Actually, I think those of us on Medicare do about as well as anyone, but again, you have to be able to afford it and many can't afford anything, sometimes including the absolute basics. Just my opinion........

Thanks for the reply.
