Free or otherwise I've been in enough 911 calls and ambulance responses to know that it wouldn't fly in Ontario and I suspect in the rest of Canada.
As for Quebec. Far be it from me to put a value on the average IQ of ambulances drivers , or the doctor/person who should say "Non" to that kind of foolishness in Quebec .
But if they're like some the French Canadians I've known , I'm checking out my shoe size.
I hope the Americans don't screw up their medical system...
