Just landed at the emerson border in Manitoba, I'll quickly share my experience since some people have been asking.
We drove to boarder from wpg, at the USA immigration I told I was there to flagpole, I just became a PR and need to do my landing. He asked me where I lived and what do I do in wpg. I answered and he asked me to park the car and wait. We parked and waited inside the US immigration building. Another officer came with the refusal to enter US document and told us she was gonna open the gate so we could drive to the Canadian immigration. She was very nice and explained how to get there. So we drove to the CAD immigration, told the officer we were there to land, she said she only needed my passports and then she gave us the passport back with a yellow slip and told us to park the car and go inside. We enter the building, there was no lines so we were served right away. The immi officer just got our passports, told us to sign the COPR letters and wait. There were NO QUESTIONS asked to us, after 15min he called us, gave us our passports, asked if we have any questions and congratulated us for becoming PR. Very very smooth.
