How to Get a SIN as an International Student in Canada
International students need a Social Insurance Number to work in Canada. A temporary resident can apply when a valid work permit, study permit or visitor record authorizes work in Canada. If a study permit should authorize work but the required work condition is missing, contact IRCC about amending the permit before applying to Service Canada.
Check Your Work Authorization Before Applying
Read the conditions printed on your immigration document first. Service Canada requires a primary document that proves your status and work authorization, plus a valid secondary identity document. The exact document must match your current status.
A Social Insurance Number (SIN) is a confidential nine-digit number used to work legally in Canada, get paid and pay taxes, file income taxes and access government programs when eligible. Temporary-resident SINs begin with 9 and normally expire on the same date as the immigration document that authorizes work.
Who Is Eligible for a SIN as an International Student?
International students can apply for a SIN when they are legally authorized to work in Canada and their valid immigration document shows that authorization. A study permit must contain wording that the holder may work or may accept employment in Canada.
What a temporary-resident SIN means
A SIN is required to work legally in Canada and is used for payroll and tax reporting. It is also used for access to certain government programs and benefits when a person is eligible.
If you are legally authorized to work, Service Canada says you can begin working after you apply for a SIN; you do not need to wait for the number. Apply within the required timeframe and provide your SIN to your employer after you receive it.
How to Apply for a SIN
The application process for a SIN is straightforward, whether you choose to apply online, by mail, or in person at a Service Canada office.
Documents International Students Need
For temporary residents, Service Canada accepts a valid work permit, a study permit that states the holder may work or may accept employment in Canada, or a visitor record that explicitly authorizes work. You also need a valid secondary identity document showing your legal name and date of birth.
Service Canada requires the primary status/work-authorization document and a valid secondary identity document. Supporting documents may also be required when names or other information differ. Use the current Service Canada required-documents page for the exact situation.
Practical Tip: Make sure your study permit clearly states that you are eligible to work in Canada. If it does not, you may need to apply for an amendment.

How to Find or Confirm an Existing SIN
Finding an existing SIN
If you lost or forgot your SIN, do not apply for a new number. Use Service Canada's current options to find or confirm your existing SIN, including obtaining a SIN confirmation when needed.
Protect Your SIN
Once you receive your SIN, keep it secure. Your SIN is sensitive information that should only be shared when necessary, such as with your employer or for tax purposes.
Avoid Scams
Treat unsolicited requests for your SIN cautiously. Verify why the number is legally required and use official contact channels before sharing sensitive information.
When a Temporary SIN Expires
After receiving your SIN, you should take a few important steps:
Temporary SINs begin with 9
Service Canada states that a SIN issued to a temporary resident begins with 9 and expires on the same date as the work permit, study permit or visitor record that authorizes work.
Update the SIN record after a new immigration document
When your immigration document is extended or your status changes, update the expiry date or status on your SIN record so it matches the current immigration document.
Store Your SIN Safely
Keep your SIN confirmation securely and avoid carrying or sharing the number unnecessarily.
Conclusion
Obtaining your SIN is a critical step for any international student planning to work in Canada or access certain government services. By understanding the application process, ensuring your documents are in order, and knowing where and how to apply, you can secure your SIN quickly and efficiently. Always remember to protect your SIN and use it responsibly to safeguard your personal information.
