Pretty smoothly really! We went into secondary and quickly saw a CBSA guard. I handed over my passport and COPR, he looked over it and then asked me what my address was. I began to recite it but then he stopped me and asked, "Do you have a driver's licence or piece of ID with it on?"
When I said, "No, I don't have a BC licence yet," the guard sternly asked, "You don't have anything that shows your address?" Luckily I had brought with me pretty much the entire application/evidence package along with a new bank statement which had arrived a few days ago, so I gave him that and he said I could take a seat. After about 5 minutes, he called me up again, had me initial and sign parts of the COPR to confirm i understood the conditions and that the information was correct.
He then folded and stapled my COPR into my PP, went away and came back with a little Canadian flag, an information letter for new PRs and a more relaxed/happy face! He explained that my PR card would be mailed to my address in 6-8 weeks, handed me the flag and said "Congratulations!"
We then left to get back to the car, another guard gave his congratulations too and we headed back home.
