Finally, after researching through various forums and posts and help and guidance of fellow members we decided to cross the border from US to Canada via Ambassador Bridge in Detroit, Michigan on 30th April 2010.
We started on Thursday night and stopped over night around 15 miles away from the border. We started around 10:30 in the morning and drove on the Ambassador Bridge. No one stopped us on the US side; we paid the toll 4 USD/4.75 CAD and drove through.
On reaching the Canadian side, it was a long queue and finally our turn came. We had put our papers together and in the order of Visa/Passports/COPR, 2nd set was Proof of funds and other documents that might be needed like degrees etc and finally the 3rd set for Customs.
The office on the Canadian side was polite and asked us for the paper work and details like what are our plans, are we going to stay there, are we importing our car, or bringing any stuff that is prohibited in Canada etc etc , routine questions. Then he handed us a yellow slip and asked us to park the car near the immigration office. When we parked the car, another office approached us , looked at our papers and asked us to proceed to the immigration dept area and told us to leave the keys behind in the car with glasses down.
We then entered the immigration office where a notice board said to wait for our names to be called. Finally in few minutes it was our turn and she looked at our papers, she asked us only one question that we are aware of the fact that our residency counter starts from today, as we had told her that we need to go back and wind up with some things before we can move permanently. She did not ask for any other documents. When she asked us where we want our PR Cards to be sent, I gave her my friend's address. She asked for his contact number and everything went on smoothly from there.
After that we went to the Customs area and gave us the printed list of goods to follow.
He looked at it and signed on it.
The landing process was done.
We then went to the nearest service Canada office and applied for our SIN cards.
We had a slightly tough time while coming back to US, we were asked about our short trip to Canada and basic questions. Then our car was searched and another officer asked us about our visit to Canada. Finally they let us go and we were back home as Canadian Permanent Residents..
It looks like to me that informing the IO that you will be moving to Canada in November made the IO not to issue the PR till you move in.
