I wasn't worried about the AOR but I have got it today afternoon. I am not too sure if I am on Nov or Dec sheet or on the sheet at all. But I hope I would let you guys know few points which may reduce your stress.
1) I sent my application with Canada Post on 28th Nov. Delivered on Dec 3rd- was with tracking
2) I didnt bother myself to see who received it cause once upon a time I was working as a delivery driver and most of my customers wouldn't even worry about signing the handheld. they just used to verify the quantity and match it with my handheld. most of the time I used to write the name of the receipt cause in case if my company asks whom did i deliver on certain date at certain location, I wouldn't know if i dont put the name. thus putting name helps me to memorize the name of the person who received it
3) I did not write my name in the back of the photos( caude I did not see it required in guide). although they were stamped/dated by costco.
4) I had my driver's license and my health card two things attached
5) I am from Regina
6) my friend who had applied few days before me has also got his AOR few days earlier than me. he is from Regina as well.
7) I read it somewhere that IRCC intentionally skip few days/weeks of each month just to keep the "average" processing time minimum- I believe this is true. cause I have seen the same pattern over with 3 different Canadian Visa offices in 3 different countries- Including NDVO.
kan-sri might know it well since he was there too in spousal visa application with NDVO and they used to do the samething- skipping days/weeks
