You need a Social Insurance Number (SIN) to work in Canada. This means if you are expected to work as a teaching assistant (TA) or any kind of employment on- or off-campus, you must have a SIN before starting your position.
There is no fee to apply for your SIN. You can apply online, by mail, in person at a Service Canada Centre, or attend one of our many in-person clinics on campus (if available). It may also be possible for you to apply for your SIN at the Toronto Pearson Airport when you first arrive in Canada (note: this service is only available during business hours, for passengers who have just arrived in Canada). You cannot apply for your Social Insurance Number if you have not arrived in Canada.
There are two Service Canada Centres in Hamilton:
- 1565 Upper James St, Hamilton, ON L9B 1K2
- 700 Queenston Rd, Hamilton, ON L8G 1A3
