I applied for PGWP on June 16 and it was approved on Nov 26 and delivered to me on Nov 30. I have my off-campus work permit and was fortunate enough to (eventually) find an employer who understands "implied status" thing.
I mailed paper application (IMM form, passport, copy of PGWP, photos) for TRV right after receiving PGWP and it was delivered to Ottawa office on Dec 2 . I'm a little freaked out for TRV now because I have friend's wedding to attend on Dec 26 and I have to leave Canada by Dec 24 due to the time zone difference. I guess this is not considered as urgent as those who have family emergencies, but she's been my closest friend since we were literally 7 or 8, so I can't imagine if I have to miss her most important life event
Another friend who applied for PGWP in early July got hers in mid Nov (a week before me), though we are graduating from a same university, submitted the same type of materials...So I really don't know if CIC is respecting the submission time frame that much. Best of luck for those who haven't got it yet!
