Refund Policy
  • Students whose study permit applications are still pending may request a deferral to the next available intake, provided the request is submitted before Day 10 of classes and the program is available. Deferrals are granted only once.

  • Students awaiting an IRCC decision must still meet the deferral deadline. Requests submitted after Day 10 of classes will not be approved solely because a study permit decision is pending.

  • If a study permit application is refused, students may defer their admission and request a new Provincial Attestation Letter (PAL) to support a future study permit application. PAL issuance is subject to availability and cannot be guaranteed.

  • Refund requests due to study permit refusal must include a copy of the official IRCC refusal letter and be submitted within 14 days of the refusal date.

  • Only the refusal letter associated with the intake being withdrawn from will be considered for refund eligibility.

  • Students whose second study permit application is refused before the start of classes may still qualify for a refund, subject to Seneca’s refund policy.

  • Deferral requests are subject to program availability, and late requests may require a written appeal.
