^ But Kelthaz said, "Yes, there are no restrictions what-so-ever on health care for anyone." You say "You certainly can't get any treatment you want here." Those can't both be true.
Of course there are some restrictions. If I get a cold I can't call for a private jet to take me to the hospital. And you can't demand whatever insane treatments you want at a moment's notice. But, well, there are no restrictions that will compromise your health*
. No matter who you are, no matter how much money you have, you will be given access to proper medical treatment. You might have to wait for a long time if your case isn't life-threatening, but you won't be denied anything that your doctors deem necessary.
Keep in mind that the United States is the only first world country that does not have Universal Health Care. Clearly, if wealthy countries with high standards of living all have Universal Health Care with just one exception there's some merit to the idea. It's not just some hippy, idealistic pipe dream.
* Okay, okay, dental isn't usually covered in Canada and that can compromise your health, but meh. I never said Canada was perfect.
