Hey, yes I received an e-mail on Friday letting me know I've been admitted. The e-mail said I will be received an official letter in the mail shortly (still haven't received it).
I thought about e-mailing the department as well! Hopefully they reply to you soon. I just want an answer from uoft so I can make my final decision on where to go. Hopefully I receive a letter in the mail today, fingers crossed!
I also applied to uoft for a masters in history and I'm in the same position as you. My status changed to "decision made" on Monday and I haven't received any e-mail or mail. It's so stressful!
