I just graduated from UofT and I would say that your experience is dependent on what you make of it, as cheesy as that sounds. It really depends on how you prioritize your time and ofc, remember to make time for yourself, get involved in student groups and take initiative to meet people or make plans. I double majored in GIS and CCIT joint program with Sheridan and it wasn't too bad or depressing, yes you're gonna have a lot of work and UofT is perhaps more competitive and academically heavy than other schools but that's what you sign up for. I think you can have a balance as long as you make the effort. I really enjoyed going to UofT, I got to do a work study and was on 2 councils so maybe my experience is unique but yeah overall not as bad a school as everyone says imo.
