Regarding the University of Toronto: I am currently studying there and my understanding was that everyone who would be either accepted or waitlisted was contacted on Sunday. As has been noted, the slots for non-Canadian students were INCREDIBLY competitive this year - even amongst the international students already in the MA program, there were those who were not accepted as PhDs.
Since the results board has been quiet lately for Harvard, I assume that all the good news has already been sent out? It seems as though most of the acceptances came via POIs and I wasn't sure if any official news had yet been dispatched - at this point, that's all I can hope for.
