Well, there's some feeling that it's a thin edge of the wedge. It's a bit silly really, because after all (a) doctor's offices are private enterprises, (b) hospitals are set up on all kinds of models, mainly but by no means exclusively not-for-profit corporations.

I've taken so long answering this that I can't remember exactly what the kerfuffle was about this time, but it's probably related to the Supreme Court decision about buying private insurance if one's wait for public care is unreasonably long (http://www.cbc.ca/news/background/healthcare/index.html).

...I should probably read up on the stuff in that section. It seems full of useful info.
