What course to choose for University, and best University in Canada or UK?

I know this is a big choice and I shouldn’t be relying on a website for this…
BUT
I am really interestied in international development.
Something like studying business or economics, and somehow travel to developing countries to help them with economic structure. I’m guessing this would be through the government some way…

are there any courses that would be best for something like this, and in particular Universities in Canada or, preferably the UK for this kind of study?

here are search results for "University in Canada"
