Hi again,
So today we went to Canada-US border (Niagara - Rainbow Bridge - even though the weather was really bad today - SNOW

). Both the parent and dependent were already in Canada. The procedure was really smooth and quick. At US immigration toll, we showed our passports and told the guy that we are here for 'Flagpole' and returning back to Canada right away. He directed us to an office and told to stay there and an officer will come to see us shortly. After 5-6 mins, an officer came to our car and gave us a piece of paper (Entry to US refused - this is administratively and there is no rejections stamp on the passports. So it won't effect future US visits). He then told us to take a U-Turn from the gate, give that paper to US immigration toll and then I can go back to Canada side. [Never left the car at US side and it hardly took 15mins there]. At the US immigration toll on our way going back to Canada, we gave the piece of paper received from the US officials, paid C$4.75 fee (don't remember what for) and then went back to Canada side.
At Canada side, we told the guy that we are here to change our landing status. He showed us the way to park the car there and then go inside some building over there. Inside the building, there were many desks with the Canadian Immigration Officers. We went to one of them and told the immigration officer that we got the CoPR and we are here to change the landing status. She kept our passports and CoPRs and told us to wait and she will call us again. After about 30mins (it was lunch time), she called us, asked us to sign on the CoPR infront of her. She then gave one copy of CoPR to each of us and told us that our PR cards will be mailed to us in 6-8 weeks. Meanwhile, we can show these signed copies of CoPR and our passports as a proof of PR and that's it.
So we are landed immigrants now
