Getting a Social Insurance Number (SIN)

In order to work in Canada, you must make sure that you have (1) authorization to work and (2) a Social Insurance Number (SIN). You can obtain a SIN at a Service Canada office — please see the Working in Canada section of this website for more information about work authorization. Your SIN will expire at the same time as your Study Permit or Work Permit.  If you would like to renew your SIN, you will need the same documents as you did for the initial application. Please note that there is no fee for getting the SIN number and in most cases the SIN will be given to you when you apply for it. Service Canada has stopped giving out SIN cards as of March 2014. So all you need is your SIN number.


Apply for your SIN in person at a Service Canada Office. Here is a list of Service Canada Offices near campus that process SIN applications.


  • 25 St. Clair Ave. East, Toronto, Ontario,  
  • 559 College Street, Suite 100, Toronto, Ontario
  • 100 Queen Street West, floor 1 Toronto Ontario.


Additional offices and locations can be found on the Service Canada website
