Promised to share my landing experience so here it goes.
Landed on Saturday at Rainbow Bridge Niagara. Finding the bridge was simple using a map.
Drove to the USA and was stopped by the USA officer, he asked for my passport (good to have it handy).
Gave him the passport and told him straight away that I came to complete my PR process and came for flagpool since I didnt have a USA visa.
He called another officer and directed me to a gate (like 10secs drive). The second officer asked me to park and wait for another officer for further instructions.
The third officer came out in about 1 minute and opened a gate, gave me an "entry denial letter" saying that I should show this on the canada side.
Drove back to canada...(another 10secs drive). Met the first Canadian officer at the toll gate, paid $3.50 and drove to the Canadian Boarder Office..(like 1-2 mins drive).
Got to the check point(second toll gate), the second Canadian officer, who was extremely nice, asked for my passport and the letter the USA guys gave me. He asked a series of questions that had obvious answers of NO....(do you have a gun in your car etc). After there he directed me to the parking spot and said I should go into the office.
I got to the office and gave my passport and letter from the USA to them at the desk and was asked to sit down.
I came in early (about 8am) there was literally nobody at the waiting area. Just me.
I was called to the desk....nice looking female officer( I believe they are called Officers as well). She asked for my COPR and category (CEC), gave it to her, she did some paper work and asked for my ID to confirm my address, gave her my driver's license.
She then asked another series of obvious NO answers and I signed the PR documents. Then she said welcome to Canada.
I gave them back all the work permit documents I had and left the building like a BOSS. Next stop? Niagara falls.
In all, the process was under 10mins. I didnt even have to show POF or employment letter of any sort. Just the documents that came with my passport from ottawa....and of cos my driver's license. The return of work permit documents I had to remind them.
Hope my long story makes your journey to LANDING a smooth one...Peace out
