Is going to UTSC life sci (health sci stream) a bad idea?

I’ve wanted to be a doctor for a long time now and was recently accepted into UTSC Life Sci. I’m currently weighing my options but my mind keeps coming back to the "uoftears" reputation and its kind of worrying me. For context my current course load consists of IB Math, IB Chem, Physics 12, Bio 12, and Psych 12, so I'm already used to a heavy science and math workload. I do have a good amount of faith in my time management and studying skills, although i know things don't always go your way. Basically i just want to know, is the grade deflation/difficulty really that bad for GPA as people say and is it a good idea for me to weigh utsc life sci as an option or if i should just forget about it. Thanks for any insight!
