I didn't apply to control group, but I applied to communications group. I'm currently doing my masters and did my ungraduated at U of T. I hope the following information helps: Based on my experience and the reply I got from grad office, U of T has a rather long admission process. It will last for several months. There are 3 rounds of admission, and your profile may not be visible to the professors in the first a couple of rounds (depending on when you completed your application, including reference letters). People who got admitted during the first round should have heard from the department/professors already. But it doesn't mean anything if you still haven't heard anything, as there are more rounds coming up. For instance, I've known people who got admitted as late as in June.
So don't worry.
