1. A friend of mine had severe back pains, all what he got from a family doctor was some painkillers and some stories that his back pain due to to weak muscles and he has to exercise more and wait a bit (3-6 months) before he can get some tests done. Anyways he moved to the US and week later made some tests to find that he has cancer in some serious stage. He started treatment but it was too late.
2. Another friend had spend 6 hours in ER with his eyelid cut in half (he got a branch into his eye while hiking).
3. I had some troubles with my daughter in Canada as well, don't want to go into details.
I eventually moved to the US and while healthcare here is outrageously and ridiculously expensive it is still years ahead of Canadian when you have a good insurance.
