Wait times are more a function of geography than availability (although, just like in the US, there aren't nearly enough specialists to go around). If you live in bumfuck Canada or bumfuck US, you're obviously going to have fewer world-class cancer centers in your immediate area. People will be triaged, so that you always have access to emergency care (keeping in mind the area that you live in), but less urgent care and elective care is obviously knocked to the back. Every single hospital in the world does this. (Just the other day I sat in a waiting room in the US for over an hour and a half because my doctor had to respond to a cardiac arrest.) And there's always going to be a limited number of specialists; it's just common sense. Where I live, in the US, it takes several months to even get an appointment with a neurologist. That's because you have people coming all over the country to see those particular neurologists. I hate comparing the US to Canada in making my argument, but this is not a problem of the government insurance system, it's a problem with not having enough trained specialists to go around.
Wait time statistics are also misleading because they vary by province. Keep in mind that while the federal govt sets uniform standards, the plans themselves are run provincially. I've noticed, anemically, that the worst stories tend to come out of the more conservative provinces, which makes sense since their system is probably underfunded because of the usual bitching on the right about taxes. Nevertheless, there's also been a huge increase in federal funding recently in order to get wait times down by 2010, because of complaints, even though they've been held to certain standards since the plan's inception. Again, I hate comparing the US to Canada is advocating for single-payer, but here's a good article from radical leftist publication Business Weekly:
http://www.businessweek.com/technology/content/jun2007/tc20070621_716260.htmRegarding the prohibition on paying privately: this is an attempt to prevent the two-tiered system that we in the US have today. As I said, a govt plan competing against private insurance is doomed to fail (this is my problem with the so-called "public option.") If doctor's can choose not to accept the govt plan, private insurers can easily undercut the govt plan by simply offering higher reimbursement rates, and people who have a choice (because they're healthy) will gravitate away from the govt plan because fewer doctors accept it. And just like will happen here, the public plan becomes nothing but a dumping ground for the sick, while healthier people pay lower rates for private insurance (and the private companies make money hand over fist, since all their claims have been dumped on the government). For a government plan to work, it needs to be the only game in town. That's what single-payer is by definition, and it's worked quite well in Canada. And there are still numerous private carriers which offer supplemental coverages for drugs not covered on the govt plan, dental, vision, life, disability, etc. It's just that the core services are only to be paid by the government.
And regarding patients having "nowhere else to go," this is simply not true. There are no networks in Canada like we have here under private insurance; patients can see any doctor they want. And if they don't like their specialist, well, you'd have the same problem here. If you can find another one, great, but there just aren't a ton to go around.
But overall, Canadians love their system and consider it as much a part of their identity as americans tend to do their guns. Even the more conservative Canadians I've talked to (funny, they'd be considered Democrats here) would never dream of changing to an American-style system.
I'm at a different computer, so I don't have all my links to actual studies (give me a few hours), but my Canadian wife and her Canadian friends can counter any horror story you can find with stories of being able to get care that would be prohibitively expensive here, and for other things that I as an american would never have gone to the doctor for because of the cost. Anecdotes are meaningless, I know, but I've never met a Canadian that didn't love their system.
Here's a couple for now:
