I wanted to share my landing experience here too, I hope it helps someone or the other. I landed at the Thousand Islands Bridge yesterday that is 24th of Feb. I tagged my brother along, so that I don't have to drive alone. We started at 6:30 PM evening and cruised around 260 KM from the place I live to get there by 9:00 PM. I arrive at the US border, told the officer that I was there for flag poling. The officer was funny - he said, "Oh! So you're going to be a PR in Canada?." I said, "Yes sir!." Officer said, "glad, you didn't bring car full of people, who don't have visas to enter the US and think it's fun to just come by". I laughed and said, "I could never do that." As I was the only person at the border, he took the responsibility to guide me, usually it is someone else who'd do that. I parked my car, went in to the office. I was the only person, along with the other officers. I was taken care of by a female officer, she asked me a couple of questions about my previous trips to the US, what I do, where I live, etc. She gave the flagpole receipt, and she walked me out through the doors and gave the directions to head back to Canada again. She wished me good luck, I thanked her, got in my car and then headed to Canada.
At the Canadian border, I gave the officer my passport, flag poling slip, he asked me if I bought anything at the duty free, I said no. He asked me to head straight in to the parking lot B. I parked my car, went in to the office. I was the only person. I was taken care of a male officer here. He asked, "Hello there! What are we doing today?" I said, "I wanted to do the PR landing." I handed him the passport, all the docs. He was excited to see the new visa (IRCC changed the visa design) on my passport. He said,"Oh! they changed it and made it look nice" I said, "Yes, much better than the old ones." He laughed and he showed the new visa to the officer sitting next to him, "It's cool, eh?" She said, "oh nice!". He came back to me, looked at all the docs, got my signatures. After the signatures, he said, "Congratulations, you're now a PR". I said, "Thanks a lot!" He then told me that the card will sent to my address with in 6 weeks. He also added, "If you want to travel to the states before you get the PR card, you can go ahead and do so, but make sure you're not flying as you'd have trouble getting on a flight with these docs. Using the land border to get in and out should not be a problem". He asked if had any questions. I said, "no". He said, "well, enjoy the rest of your night". I thanked him and said, "good night".
Overall, my experience was great! Both the US and Canadian side. I'm a frequent traveller and I've always had amazing officers at both sides. I understand that some people have reported here saying they have had bad experiences. They are humans too, you never know what their day was like. Either ways being good to each other is the key! Good luck to other folks in the process and the ones who are just getting started. Peace!
