Mine was delivered oct 15 and got aor two days ago. so they are slowly 'receiving' delivered applications. Wait for another 7-10 days to get your AOR email.My application was delivered on Oct 24, 2018. However, I have not received AOR or returned application via post and I see that some people that their application was delivered after that they have received AOR. I wonder what is going on with my application am anxious to know. I can't their IRCC help line to answer calls.
UpdatedFinally got my AOR today, Jan 10, please update, thanks!
PS: was worried that it took too long and no AOR (my app was delivered on Oct 3), so I sent them a case specific inquiry 3 days ago. Didn't get a response but the AOR came today, so for those of you who are waiting for more than 3 month you may consider doing this.
