I don't know enough to be able to answer your question.

However, even if you did find a country you could do this in, you'd have to deal with the cost and time required to travel there, consult with the local doctors, get the surgery scheduled, perform the surgery, and remain for post-op care - all of which would be likely out of their own pocket.

Canada has universal single payer health care system and I have no idea how they deal with medical procedures done outside the country. I highly doubt they would cover unless they were on private insurance that allowed it.

Not everyone has the means to do what you suggest unfortunately.
