Social Insurance Number (SIN) is an important document, that you need to work in Canada or to have access to government programs and benefits.
A SIN is issued to one person only and it cannot legally be used by anyone else. Service Canada is now issuing SINs in paper format (confirmation of SIN letter). Production of the plastic SIN card has stopped.
To apply for your SIN, to obtain a confirmation of your SIN or to amend your SIN record, simply gather all the required original documents and take them to the nearest Service Canada office. If everything is in order, you will get your SIN during your visit. Click here for the list of documents accepted.
