Social Insurance Number clinics

A Social Insurance Number (SIN) is a 9 digit number that you need in order to work in Canada or to have access to government programs and benefits. You will need a SIN if you want to file an income tax return in Canada.

You can get a SIN by applying online or by mail. You will need the documents listed in the Booking and Documentation section below to apply. If you have permission to work in Canada but are currently outside of Canada, the SIN can be mailed to your country of residence if your proof of address is accepted and all requirements are met.

If you are unable to apply online or by mail, you have the option to apply in person at certain Service Canada Centres.

At certain times of the year, you can also apply on campus at the Centre for International Experience. If SIN clinics are running, click on a date under Booking & Documentation to register on CLNx and select an appointment time.

Once you have your Social Insurance Number, you must update your profile on ACORN. The University of Toronto will request your Social Insurance Number on ACORN to include it on the tax forms they issue. If you are not eligible for a SIN, you may apply for an Individual Tax Number (ITN).
