Well, as we learned at the time of Diana's death in France, different countries have different approaches to medical care - both emergency care and day-to-day care. So WHERE you are when you need emergency care can have a great bearing on the outcome.
After my own experience I would NEVER recommend a skiing trip to Canada. Period.
Also, FWIW, while I staying there in Canada I learned (from speaking to three different lawyers) that Canadian ski resorts have NO LIABILITY for the safety of their slopes or for any injury to a skiier. I asked one of the lawyers "You mean I could just come up here and buy some acreage on the side of a mountain, install a lift and say "Go to it" and there would be not requirement for me to look out for the safety of a skiier by installing fencing, hay bales, or anything like that? " and his answer was "Basically, yes. We do not have liability laws here like you have in the US".
