Apply for a Social Insurance Number (SIN)

A Social Insurance Number (SIN) is a number that the Canadian government requires for taxation purposes.  If you are working in Canada, you require a SIN to get paid. A SIN is required only if you earn income in Canada (eg. on-campus employment).  This number enables your employer to make the necessary government deductions.

You must provide your SIN to your employer within three days of starting work.

You must apply to Service Canada for a SIN.  You may apply online, by mail or in-person at a Service Canada office.  For details of how to apply, review our "Social Insurance Number" instruction guide. 

Important: Your SIN will expire at the same time as your immigration document (e.g. study permit). When you renew your study permit, remember to renew your SIN, if eligible.

Note: A valid SIN alone does not authorize you to work on and/or off campus. You must still meet the IRCC work eligibility requirements in order to legally work in Canada as a study permit holder, even if you already have a valid SIN.
