But man, when you do have a medical emergency, it's great not having to think about whether you're going to have to remortgage your house, sell your kidneys, put your kids up for adoption or reconsider all of your life plans.

Personally I think Canada is a little bit over-dogmatic about rejecting a parallel private system entirely: I know there are problems with running two systems (mainly around inequity and brain-drain incentives for healthcare workers to move out of the public system), but IMO, nothing that can't be fixed by sufficiently high prices/taxes.
