Masters of Computer Science as a UTSC Coop student

I am a 2nd year CS specialist at utsc entering my second (private) research based internship and I'm seriously considering grad school. Continuing at utsc is not really an option because of their tiny post grad program and small pool of supervisors to select from. Therefore I would likely focus on utsg. My first two year marks were okay, I'm at a 3.5 cgpa rn, I have slowly improved my study habits and am projecting a 3.7-3.8 sgpa for last semester of second year (but taking mostly 3rd year courses). If I can keep this up how should I go about finding a supervisor given most of my profs at utsc were former utsg profs and have retired from that to just teach. I have a first name relationship with some of my profs due to club hackathons but that feels kind of useless if I go to utsg. Also what is the domestic cost, I know tuition is posted ... I'm more looking for how much ta jobs and scholarships have offset it for people. Thanks.
