I think there are still some big challenges that you haven't fully considered. Am I right in thinking that you haven't started at your school in Canada yet?
As you get older, you can expect to spend more time on your schoolwork and on extracurricular activities. By the time my sister and I were in our last years at school, we were involved with music (choirs for me, flute, drums and orchestra for her), sports (swimming for both of us, martial arts for me, netball for her) and lots of schoolwork. I think having some kind of extra-curricular activity is important: you learn new skills, you get to meet people from different backgrounds, they provide a space that isn't school, they teach confidence and patience and persistence. If I had a child your age, I would want them to have the opportunity to do these things so that they could grow into a well-rounded adult.
You don't know how hard it is to find somewhere that will rent to a student who has a pet. Frankly, it's annoying as an adult who earns enough to offer a whacking great deposit which, as a student, you won't be able to do. You don't know what it's like living with roommates, or what it's like to even find roommates who are reasonable humans instead of completely feral. I have stories that will make your hair stand on end!
You don't know what your workload will be like in college. You don't know if you'll be involved in student or social activities. You don't know if you'll have a girlfriend or boyfriend who you'll want to spend time with. You don't know if you'll want to just take off for a weekend just to visit another city or go on a hike or go to a music festival.
I would hate for you to miss out on a lot of fun and freedom. All of these experiences ultimately make you a better bird owner when you're settled enough and independent enough to bring a bird into your life.
