Thank you for asking the question, because I was just wondering the same thing (kept wondering what AOR stood for, haha).. We sent in Aug 17 and just this morning I got confirmation from Canada Post it was delivered. Unfortunately I didn't know that signatures are not included in Xpresspost and you have to ask separately for them.. the guy never offered the option to me. But oh well, at least I have tracking and confirmation it arrived there and now knwo to expect something in 3-4 weeks.
Does anyone know if the "time" starts ticking from the day it was received, or from the day CIC sends the acknowledgement 3 weeks later? It would make a difference to the police certificates that we sent in...
