The job market is pretty strong, so you may be able to get a part time job helping out at an architecture firm.  Just know that architecture firms are all over the map in terms of what the work environment is like.  If the first (or second or third!)  job you get sucks, don't necessarily give up on the industry.

If you don't like arch school, don't worry.  It's very far removed from what real architects do all day.

Emil, perhaps it's not clear to you yet, but first year in arch studies is pretty much a return to grade-school level art classes.  You're expected to play around with the basics (light, shadow, shapes, colours, etc) and do dozens and dozens of iterations of seemingly useless "spaces" and whatever all while trying to navigate the rest of the normal university things.  This is/can be overwhelming for young people but it serves a very important purpose:  It knocks down the A-level students who only feel confortable in linear learning environment and it helps break down pre-conceived habits of what is "design".  If you don't like the abstract nature of the program so far tho, you're in for quite a ride.  

Second to the above, note that you won't really be learning anything related to the practice of architecture for a few semesters at least... even less at UofT since it's a general arts degree, not a arch tech (Ryerson) or a hardcore arch studies (Waterloo) bachelor.  You will definitively need to work very hard because the school severely underserves it's cohorts in terms of real-life skills... but first you need to convince yourself that you want to study/work in the design field.  This last point is key because not everyone who studies architecture eventually become licensed or even touches building design.  Many go into design-adjacent fields, product marketing, or construction management to name a few examples.  

But don't get ahead of yourself in the first week of the first semester of first year.  This is the time to explore your creative problem solving skills while learning to play with spatial designs.  There will be plenty of time to learn the normal aspects of building design and construction later but those early first years are crucial.

I've seen many many students like you back when I sat on the interview board for Waterloo and even when I taught my own little first year studios.  

Thanks for the info.

Whatever you decide, it is absolutely NOT "a bit too late" for a course correction. Don't go into architecture or anything else thinking that you are somehow a prisoner.  Particularly not at your tender age.

hilarious how people say they don’t have money yet don’t do their research to save money, especially in higher education.
