OK. Long post warning! I had wanted to share my experience to this helpful group and here it goes.. I landed in Buffalo, took a rental car and crossed into Canada via the Lewiston Bridge. I did not choose the border.. Google did.. It was literally empty. I showed the officer my Passport and expired PR card. He asked me how long I was in US (1 day) and how long was I out of Canada (5 years). He started writing this on a Yellow piece of paper, handed it to me and asked me to proceed to the Main Entrance of the building on the right. I handed in the yellow slip, Expired PR card and my PP to one of the officers inside the building and was asked to wait. In about 15 mins, I was called by an officer to explain my situation. I had a family member illness situation due to which I had to be out of Canada which led "partially" to my RO non-compliance. However, in my case, I also had a confirmed job offer letter in a Canadian company, and a rental agreement to show that I intended to settle in Canada. I also had prepared a file with these documents along with the relevant medical reports. This file was reviewed by the officer- believe me..they thoroughly review . Then he handed over my passport plus expired card and said I am good to go! No paperwork to sign, no official document handed over..So, I am assuming that I was not reported. At this point, I cannot pinpoint the exact reason why I was let go..reasoning this would likely be complex.. I am thankful to all the responders of my queries in this Forum. This forum has surely helped me prepare for this. Most important prep I felt was the file. Each case in unique and it really depends on each one's circumstances on what happens at the border. CBSA officers were very professional, none of them had a questionable or intimidating attitude.. I did not use any lawyer. This forum was pretty much what I used to check everyday

. Upon entering, I managed to visit Service Ontario to reinstate my Health Card (rental agreement was useful to prove address and intent to stay; aligning with earlier comments in this thread) and visited Drivetest to take knowledge test and successfully got my G1 license too. So, overall, a positive experience. Again, this is my experience and it may or may not be the same for others as circumstances differ.. Good luck to anyone who is planning to cross the border into Canada with an expired PR card and with a true intention to settle here.
