How to apply for SIN

International students are required to present their study permits when applying for a Social Insurance Number (SIN). Details on how to apply can be found here.

A study permit issued by CIC is acceptable only when it indicates that the permit holder “may accept employment” or “may work” in Canada. If neither of these statements is on the study permit, the international student will need to submit a request for an amendment to their study permit before a SIN application can be completed. There is no fee for this request. If you need assistance or advice on the process, please contact the ISA office to schedule an appointment with a registered and certified immigration consultant.

To apply for a SIN, international students must present either:

  • a study permit issued by CIC that indicates the permit holder “may accept employment” or “may work” in Canada; or
  • a study permit and a “confirmation to work off campus” letter issued by CIC prior to February 6, 2015.

Note: The language in the aforementioned points is taken directly from the Service Canada website.
