I don't think Canada has longer wait times in general, although of course they might on specific surgeries or operations or procedures, but that's true for every country in the world.

I live in Japan and I've never had any of my friends or acquaintances ever tell me that they had to wait a significant time to get the treatment they needed. This includes many people who have serious medical conditions of various kinds in middle and old age. So even if you can find a country that does national health care poorly, it doesn't mean you should copy them because many other countries are doing it well.
