I know several Canadian citizens who moved to the states in a large part to escape the inferior national healthcare system up north. I suppose if you work part time at McDonalds, government run health care seems like a good idea, but if you have a job where you can actually afford real healthcare, it's terrible.
Amazing isn't it, how everyone has an ex-girlfriend's former roommate's Canadian cousin who has some unpleasant anecdote the public health care system, isn't it? I almost wonder sometimes if these are all the same person.
Well, I am Canadian. And I can say that while our system isn't perfect I honestly can't see it being vastly inferior to whatever you have down there, unless maybe you get wine & cheese and digital television in every waiting room.
I'm still fairly young with no major health problems, but of course I have friends and relatives have had serious medical issues (e.g. heart attacks, liver & stomach trouble, cancer) and by all accounts got perfectly acceptable treatment. Of course we have the occasional scandal: for example some doctors in Newfoundland a few years ago misdiagnosed a lot of breast biopsies, missed a number of cancer cases, and some women died, but that was pure incompetence and there's no obvious reason why a private system would've avoided that.
Canadian immigrants to the U.S. are not a statistically valid sampling of the Canadian population. I have a friend who's now in the U.S. who badmouths our healthcare system regularly, but that has more to do with his being a libertarian than from any actual bad experience, which he grudgingly admitted to after a long argument.
