Hello everyone.
Does a 1980's SIN expire after loosing PR status due to RO not met? My parents lost theirs but now will recover PR status (PGP).
I was wondering if the old SIN is still valid. Same with healthcare card.
The old SIN remains and is 'valid' but will almost certainly be in dormant status (as explained by
@Copingwithlife) .
Basically they will need to contact Service Canada and provide some updated documents. I believe this can be done at some (but not all) Service Canada locations, or by phone plus mail.
They should not try to get a new SIN, but just deal with the process - it's not that onerous.
Background: have done this for my spouse (who became a PR some years ago, left and eventually renounced PR status, and then we returned together via sponsorship), was not an issue. Don't recall exactly what needed to be provided. We did this by phone and got sent a form which we returned with some doc.
Note that the SIN is not 'invalid' even if dormant, they can use the SIN to work. The employer might get an inquiry to confirm identity. If they expect to work right away they might prefer to visit a Service Canada location, would be faster - but I'd call in advance to confirm what they need to take.
