Students Studying in Canada Social Insurance Number (SIN)

A Social Insurance Number (SIN) is a 9-digit number that you need to work and be paid in Canada and access government programs and benefits. It is also used to file taxes.

If you are not eligible for a SIN, you can apply for an Individual Tax Number (ITN) for tax purposes.

You are responsible for protecting your SIN. Ensure that you store documents containing your SIN and personal information in a safe place. For more information about protecting your SIN, please visit here.

International students get a SIN starting with the number ‘9,’ which lets employers know that you are a temporary resident in Canada.

A Social Insurance Number (SIN) is fundamental to working in Canada and accessing Government of Canada programs and services.

To avoid waiting in line at a Service Canada Centre, you can apply for your SIN online. A completed online application with all the required documents will be processed within 5 business days. You will then be able to view your SIN in your My Service Canada Account. It is highly recommended that you apply for your SIN using the online application.

When Can I Apply for a SIN?

You can only apply for your SIN after you have arrived in Canada and you have received your valid Study Permit.

The expiry date of the SIN is based on the permit that authorizes you to work in Canada. Each time you extend your study or work permits and you want to continue working or file your taxes, you have to renew you SIN with the new or renewed permits.

Your SIN is confidential. You should not use it as identification or provide it for job applications, rental applications, etc. Please read more about how to protect your SIN here. Or click on the PDF below for more information:

A valid SIN alone does not automatically make you eligible to work on or off campus. You must still meet the eligibility requirements in order to legally work. Students in degree programs do not need a work permit to work off-campus.

Please email us at [email protected] to connect with an OGS Canada International Student and Scholar Advisor if you see “This permit does not permit the holder to engage in off-campus employment in Canada” under the condition section of your study permits.
