I was landed Vancouver in 2011 and then back to my hometown without fulfilling RO and didn’t got the SIN card. My pr card expired on 7/2017. However, I am now want to back to Canada and fulfil the RO, I have the following questions want to clarify: 1. Is it possible to got the sin card by having the landing paper but not the expired pr card? 2. Is it true that all people travel or enter Canada required to give the biometric information starting from December 2019? Please ignore my grammatical errors, I am sorry.
