Oh wow, I'm sorry. I thought the received date was the same as AOR. I am not seeing any mention of AOR in the GCKey or ECAS. I cannot recall if I ever got an AOR. I am checking through my emails and through my mail but I can't seem to locate that. This is my second time filing though, the first time around they had returned the application because of a missing signature. It took them 3 months to actually open the file and see that I had typed the name electronically but was missing the hand written signature.
In any case, that application was sent out around this time last year, and it took 3 months for me to hear back from them. I guess they really do slow down in the summer.
I would try calling them at 888-242-2100 if you are in Canada. The other 613 number doesn't really do anything, they just tell you to send a webform.
I hope that helps. Even though it is a little silly that I don't know what my AOR date is....sorry "/
