Social Insurance Number (SIN)

A Social Insurance Number (SIN) is a unique nine-digit number issued by Service Canada. It is required for international students who plan to work in Canada or access government programs and benefits.

Who Needs a SIN?

  • Students with a valid study permit that includes a condition allowing them to work. The study permit must state that you "May work" or "May accept employment"
  • Spouses or common-law partners of full-time students who receive an open work permit and wish to work in Canada.

HOW TO APPLY FOR A SIN?

You can apply for a SIN for free through Service Canada online, by mail, or in person at a Service Canada Centre.

REQUIRED DOCUMENTS

  • A valid study permit that indicates “may accept employment” or “may work” in Canada or Work permit
  • A passport or Canadian provincial ID or Driver’s license for identification purposes

YOU CAN'T APPLY FOR A SIN IF

Your study permit does not include work remarks

If your study permit does not state that you "may accept employment" or "may work" in Canada, but you are eligible to work on or off-campus, you must apply to change the conditions of your study permit. This applies if you are:

  • A full-time student in a degree, diploma, or certificate program at the U of A
  • A full-time exchange student
  • A full-time visiting student

Your study permit includes restrictions

If your study permit states "This permit does not permit the holder to engage in off-campus employment in Canada," but you are now eligible to work off-campus you must apply to change the conditions of your study permit. This applies if you were an English Language School student and transferred to a full-time, eligible program of study.

To amend your study permit, connect with an International Student Specialist for guidance. After your study permit is updated you can apply for a SIN.

IMPORTANT REMINDERS

  • SIN has expiry dates that coincide with the expiry date of your work or study permit. If you extend your study permit or renew your immigration document, you must also renew your SIN.
  • Protect your SIN. Keep your SIN private to avoid identity theft. Do not share it unless required by law. You can share with employers or the Canada Revenue Agency.
