Does Canada have loads of social problems amongst teenagers?

[Doctor]

I have heard from some people that Canada has a very severe problem concerning social issues (such as smoking, drugs, depression, alcohol, peer pressure etc) amongst teenagers. Is this true? And would you say the problem was bigger than the teenage problems that are widespread in the UK?

In the future, I'd like to move to Canada from England but I'm worried that any children that I may have may become affected by these problems (which is why I'm asking) and like any decent parent, I'd want to raise them in a secure environment, where these issues aren't prevalent. I'm thinking of moving to Vancouver, Winnipeg or Ottawa (or a town/city which is in close proximity to one of these cities).
