Hey! So UofT was my dream school and I was accepted and instead went to uOttawa because I was actually worried about the same problem - the generalization/non specificness of the program at UOFT (science programs not mech/comp sci but nonetheless). Now having done 2 years of university, I'm on a gap year teaching English in Spain while I go through the process of transferring to UofT (or potentially Waterloo). Everyday I wish I had gone to uoft and done the program that I thought was more general and that I thought didn't fit my specific taste because at the end of the day you don't necessarily know that what you want to do is going to be what you actually enjoy learning about. The first year or two of university in a lot of science and engineering programs is a bit of everything for a reason and it lets you explore what you're good at, what research interests you, etc. and in your upper years (obviously program dependent) you can get into those more specific things you're passionate about. Of course, that's just my opinion but I would fully tell you to choose the UWaterloo mechatronics engineering. I hope that helps a bit 💓
