Just thought I would mention that offers for Western have been sent out (my friend was sent the rejection email this evening, after being short-listed for the interview a couple weeks ago).
My friend was interviewed (and then rejected) so I think those notices were only for people who were interviewed. I would suspect though that if you haven't heard back yet (and weren't invited to the interview day) that it's best to assume a rejection at this point, unfortunately.
Acceptances / rejections were sent out Tuesday (Feb. 13th), as a friend of mine received a rejection that day. This was for all the people who were invited to the interview.
My understanding is that Waterloo doesn't have an interview day like Western does, so you may still be accepted without an interview, but I could be totally wrong! Getting an interview would obviously still be a good sign.
According to the results page, two people received interview invitations already, but it looks like most people find out if they've been rejected by late February / early March.
I thought I would mention that, as of Monday, I know of two people who received invites to Western's clinical psychology interview day. Western's website says all the invites will be sent 'soon after' January 25th (whatever that means) so there may still be some time, but I'm trying not to get my hopes up.
