The Social Insurance Number (SIN) is:

• A nine-digit number that you need to work in Canada and access government programs/benefits.
• Issued to newcomers in the form of 1 paper document per person. Production of plastic SIN cards ended in 2014.
• Sponsors must explain the importance of the SIN, it’s purpose, when they will need to share it, and when not to share it. It is their responsibility to protect their SIN.

How to Apply

Newcomers will likely receive their SIN at the airport, and therefore no application will be required. However, if the SIN is not received upon arrival, an in-person application at a Service Canada Centre is required. There is no fee to apply for a SIN.
