Vancouver, Toronto, Hong Kong and Shanghai, which is the best place?

Vancouver is more suitable for China people. First of all, Vancouver is surrounded by mountains and waters, and the seasons are like spring. It is the warmest place in Canada and the first choice for many immigrants. As for Toronto, it's not bad, but it's colder in winter. I think you should understand that Hong Kong and Shanghai are not comparable to Canada in terms of living index, living environment and social environment.
