The Waterloo grad office sent out emails today notifying applicants, and when I spoke to someone there, she said that they had received results from SSHRC yesterday, and then admitted that she may have jumped the gun a bit in notifying applicants already. So hang in there, those of you still waiting!
I'm also an MA applicant, and have been obsessively checking SSHRC's twitter account, as they tweeted when they mailed out doctoral results. Good luck to my fellow anxious MA applicants!
