Hey there, I have the exactly same situation here and same date. I called post Canada, and they said that they only left mails to the boxes and CIC will pick up. CIC may have their staff to use their scanner to send the data back to post Canada with days of delay. However, if there are hundreds of mails received that day, CIC may not do it as they do not have enough staff to do it. I called CIC, and they said that they are not able to check until CIC officer open the file and enter in the system. Meanwhile, we suppose to receive AOR. I sent a service ticket in Post Canada to investigate my mail and they suppose to respond me in 5 days. Hope this info help you. I am also frustrated here.
