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 (not recommended), in person at a Service Canada Centre, or attend one of our many in-person clinics on campus (when 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.

Service Canada will be operating on-campus Social Insurance Number Clinics at the start of the Fall term. Visit our website calendar for dates and times.

There are two Service Canada Centres in Hamilton:

• 1565 Upper James St, Hamilton, ON L9B 1K2
• 700 Queenston Rd, Hamilton, ON L8G 1A3
