You can apply for a SIN with your original passport and work permit.
How to apply without a work permit
You can apply for a SIN with your original passport and study permit, as long as your study permit has one of the following conditions or remarks:
- May accept employment on the campus of the institution at which registered in full-time studies
- May work 20 hours per week off-campus or full-time during regular breaks if meeting criteria outlined in section 186(v) of Immigration and Refugee Protection Regulations (IRPR)
- May accept employment on or off campus if meeting eligibility criteria as per R186(f), (v) or (w). Must cease working if no longer meeting these criteria
Note: If your study permit does not have one of the above conditions or remarks, and you were eligible to work on and off campus when the study permit was issued, you need to submit a mailed request for an amendment to your study permit before you can apply for a SIN. There is no fee for this application. The estimated processing time can be found on the IRCC website.
Applying for an amendment is not the same as applying to change conditions of/extend your study permit. The expiry date of your study permit will stay the same in an amendment application. You will still need to apply to extend your study permit before its expiry date.
Exception: If 'This permit does not permit the holder to engage in on or off campus employment in Canada' is printed on your study permit and you have since become eligible to work on campus or off campus, you must apply to change conditions of/extend your study permit.
