Well, compared to what?
The odds of having your private health insurance rescinded in the US is also very small -- but it's quite likely among people who suddenly rack up big health care costs.
Similarly, if you compare Canada-to-US medical tourists to the Canadian population, I'm sure it's amazingly tiny. But how does it compare to the people of means who have a medical procedure denied by the Canadian system?
(I don't fault Canada for denying care in some cases. Sometimes it's not worth it. But the Canadian system would be better if people were still allowed to top off the denied care with their own dollars and didn't need to leave the country to get it.)
I could go on and on about the abuse my son received at the hands of the Canadian health care system, but I'll just say that I hate the system. At every step of the way, despite doing everything we could, my son suffered because of the system.
A part of me understands it's because it was Quebec, but Quebec is an example of how the Canadian system fails, and fails hard.
A part of me feels as if it was my fault. I should have moved sooner, when we were first lied to. But we figured if we played by the rules, things would work out. We were wrong.
So no. I'd fight tooth and nail to prevent that abuse from coming to the US. And if it did come, I'd leave. I will not let my family suffer like that again.
>> The numbers are vanishingly small
Maybe as a % of the overall Canadian population, perhaps. What about the % of critically ill? People with cancer? My aunt is an oncology nurse at one of the best hospitals in the nation, and she sees a lot of Canadians who come to the US for treatment that they can't get at home.
So yes, people with the flu or a broken arm probably aren't flocking here for care. People with serious illnesses? You bet they're coming here.
Here's a study that puts the numer of Canadians using the US healthcare system at about 0.61%: http://content.healthaffairs.org/content/21/3/19.full.html
As for that study, I'm a little concerned that they only looked at a handful of states, and this little line at the bottom:
"The authors acknowledge financial support from the Canadian Institutes of Health Research (formerly the Medical Research Council of Canada) for this research."
My guess: both your source and mine are biased and flawed, and the truth lies somewhere in the middle.
