Righto, Rig. I think that's where I might look first too. But I think Carol's point about the high costs of treatment in the USA probably has much to do with it as well.

Think about it. You get free treatment in Canada...and the doctor doesn't handle it right. So maybe you sue him for malpractice. But then, say, you get the same treatment in the USA...the doctor doesn't handle it right...and it also costs you $35,000! In which case are you more likely going to get REALLY angry at the doctor and launch a malpractice lawsuit for big bucks?

Seems pretty obvious to me...when you've just lost $35,000 dollars, that's when. Lawsuits are driven by two motivations:

1. revenge
2. and the desire to cash in.
