Hi Bro, I heard that a PO BOX willl not accepted by IRCC, I also was asked to change my initial address with a PO Box. Btw, what do you mean by "live in NL"? I live in an apartment, actually we don't have a mailbox, but consider that Amazon and UPS can deliver parcels in, I changed my PO Box address to my apartment address, I hope the postman would call me when the PR cards arrive.I also live in NL and I used a PO box address. I got COPR on Jan 24th but no one asked for any address changes. How did they ask you to change the address? Is it a mail box at Canada Post office or a community mail box?
Address still in review by the way.
