The Social Insurance Number (SIN) is used to administer government benefits under the Income Tax Act, the Canada Pension Plan Act, and the Employment Insurance Act. The university has a legal obligation to request, examine and record the SIN for those individuals who are paid through Payroll.

Payroll will not pay employment income to individuals unless a valid SIN is on file.
