I think most of Canadian broader should request passengers to drive. Heading to US broader, I was asked if I and my accompanies had US visa or not (I thought it was not required, thought we all have). Then stopped the car, went to a building, and the US officer would ask the main purpose of the trip/my status in Canada/etc. He or she would issue a white ticket to me. Held this and then backed to the car, and one officer would guide how to drive back to Canadian broader without entering the US.
Then Canadian broader was really straightforward to deal with my landing:
1. asked me to double-check the 2 CoPR paper was correct or not, and to give all my permits no matter they expired or valid;
2. asked me to write the questions on the CoPR with “no” (if no) and initial, and at the bottom full signature and date on it;
3. asked me to write down my address and how much many in my bank account...
After 5 mins wait, it’s done and he gave back my passport along with 1 CoPR (with his writing and signature) and a congratulation template paper with some details regarding PR card and how to keep it after 5 years, etc. He didn’t even mention how and how long my PR was gonna arrive.
