I got married to a Canadian citizen in 2006, got my my PR in 2008, had to move back to USA in 2009, wife moved to USA with me at end of 2010 after receiving US green card. We lived together in the USA together for last ten years. My PR card expired in 2013. We were finally able to move back a few weeks ago, I had no problems crossing border, they would not accept my expired card for entry but took my US passport instead, they asked if I was moving back as a resident and I said yes, no other questions were asked about the subject. What can or should I do now? I plan on staying in Canada and getting citizenship, I dont have any plans to leave the country. Is it best to get my card renewed even though I have no plans to leave? I have already ran into an issue where they asked for expiration date on my PR card on AB healthcare application, I have a SIN number already from my before.
