Hello 3rd year student at UofT.
If you can get a similar clinical and didactic experience for almost half the cost and live in an amazing city like montreal then I feel like that's a pretty good choice. I went to UofT mainly because my family and friends were in Toronto, but I think I would have went to McGill back then if I knew how cheap it was...
Didactic wise: I feel like dental school is pretty heavy didactically anywhere you go but a pass/fail would have been amazing because one of the largest sources of stress for me in school was the letter grade system. Being in a competitive place like UofT, everyone, whether you want to specialize or not, can't help but feel stressed out unnecessarily when one of your friends ask you how you did or you see on your transcript that you are like 2 -3letter grades below the class avg. However, there are some benefits though. I felt more motivated to study harder so that I won't get shit on in class. I doubt I would have been motivated to study as hard if it was just pass/fail. At some point (around 3rd year) I stopped caring too much about grades anyways ... too much anxiety for me.
Clinically: This is just a luck of the draw. At uoft, from what I see, most people can get the minimum credits required to graduate on time but its gonna be way harder for some than others depending on what kind of patients you get. Our pediatric clinics this year has been pretty dead - most people in my session only saw 1-2 kids and when we do we have to share them. Imagine as a kid having 4 students take turn putting 1 sealant on each of your molars - luckily the kid was pretty chill. Maybe other students from other schools can comment but they say this is mainly due to the fact that private dentists are now offering healthy smiles program to their pediatric patients so their services are covered. I don't blame the parents for choosing to go to private dentists tbh but it really does cut into our pediatric clinical experience (other students on other days saw way more kids though). Instructor quality varies a lot too and this is luck of the draw as well. Some instructors i avoided like the plague.. and others are amazing at what they do and they will teach you a lot. One of huge benefits of being at UofT is that if you get a really complex patient then there will be grad programs to help you out or take care of your patient.
Overall, UofT is a mixed bag of happiness (mainly from the amazing friends I met), tears, some blood (a lot of times not yours hopefully), and at the end of the day I feel like most students will come out of any dental school saying the same thing. However, what is NOT the same is the amount of debt you will will come out of so if being in a lot of debt scares you then I would just go to Mcgill (of course assuming you are okay with moving away from fam, and you like the city itself) if you are offered admissions there since didactic and clinical is pretty similar wherever you go and you have to be lucky a lot of times in dental school. Also you do most of your learning outside of dental school anyways, just need to get that foundation in school first.
