I'm a British citizen in need of a getaway due to anxiety, I'm 19 so still young and thinking about what I want to do with my life and when I think about moving to Canada i feel very motivated and I can't get the thought out of my head, moving to Canada is my no.1 goal and dream so I want to prepare for it as much as I can, I probably won't make it there

So what jobs does Canada need the most, the less qualifications the better the pay doesn't matter it's just what's in demand i don't care about money I just really badly want to leave this country
when you live in a certain place for too long you make friend and you lose friends but if you make enemies they're a lot harder to shake off.

I've looked into Canada the more I look into it the better the country looks, I haven't heard of any problems within Canada but it can't be half as bad as the United kingdoms problems.

If Canada isn't a good option to persue my dream of Getting away from my current life.

(I prefer answers from Canadian citizens allthough all still welcomed)
So to round them up here are my questions:-

1. What jobs are Canada looking for? (The less qualifications the better although I would prefer to put some effort in college to commit to this dream)

2. Would there be any requirement in order for me to leave for Canada? (E.g. My criminal records clean but my medical record is really bad.

3. How do Canadians feel about immigration?

4. Does Canada have any shortages on jobs?
