I wouldn't worry about it since you have so much time. Seems like you're in a pretty good spot. I'd consider getting into internships while you're in University(If you go to Waterloo, I think that they pretty much force you to do these in order to graduate) -- you can try working at some startups or bigger companies and see where you'll fit there. I wouldn't plan it out too much. You have to see what you'll enjoy through your experiences.
