Hey guys, I'm a bit embarrassed to share this update, but if it happened to me it could happen to others: received DM on Feb 7th and have been waiting for my PPR. Saw that others got their emails last night so I decided to call CIC today - as I was about to punch in my application number, I searched "CIC" in my Gmail. Alas: I received PPR on Feb 15th, and it got auto-sorted into my "Promotions" tab on Gmail. I have been religiously checking my regular email up until, which is where all previous CIC emails have gone. This particular one, for whatever reason, got sorted out as an advertisement!
Gmail users - check your spam and promotion folders, just in case.
Sent in my docs and pre-paid envelope this morning. Lost a week on this, which sucks because my work permit is expiring in two weeks - however, fingers crossed I get everything back in time.
