Hi friends My sin number got expired with my study permit on December 2019.I applied my study permit extension which takes around 4-5 months to arrive and after getting extension of 1 month I applied for my work permit on March 10,2020 and it got approved on September 10,2020.But unfortunately Canada post has lost my work permit in transit then ircc agent told me to apply for replacement of immigration document application which I do.Now it will take 30 days again.So basically i never get a valid document for a year to update sin number.Now I am still waiting for my work permit to update my sin number.Pleae anyone tell me that it gonna affect my PR in future
