Just finished my landing at Peace Bridge. I want to share the experience while it's still fresh.
I arrived at 8:30 in the morning. I suggest you arrive earlier because there're already lots of people in front of me. And make sure you come on Tuesday to Thursday.
Drive along QEW to the end and you will cross the bridge and reach the US border. Tell the officer you are flag poling and he will collect your passport and copr. He will give you a piece of paper has your plate number on it and point a way to park your car and go to room 2. Sit down and wait until they gather enough people. The officer will tell all
of you to drive to the exit and he will give back all the documents at the gate.
Then drive back to the Canada border. Give the officer your documents and say you are landing. He will show you where to park and which building to enter into. It's very close just on your right hand side.
Go in there and give all documents to the staff. Have a seat and wait somebody call your name.
I was asked 3 questions.
1. Have you commit a crime
2. Do you have dependents
3. How much money you have
No other documents needed beyond passport copr.
Then you need to do 4 initials and 2 signatures. You can keep one of your copr. The officer will congratulate you and say blahblah.
That was really quick. I think I only be in that room for like 10mins and became a pr. Lol
Ps. Canadian officers are more friendly indeed
Hope it helps
