The Social Insurance Number (SIN) is the single most important unique identifier necessary for working and studying in Canada, performing bank operations, and accessing government benefits. This 9-digit unique identifier is essential for tax purposes, pensions, and credit history.
If you are a temporary Canadian worker or student without permanent residency or citizenship, your SIN will begin with the number “9” and is only valid until the expiry date specified on your immigration documents.

Why Must You Renew Your SIN?
There are a few scenarios where you will need to renew your SIN number in Canada, including:
- If you change your name
- If you would like to have your disc number removed from your SIN record

As a temporary worker in Canada, you have to update or renew your SIN anytime the expiry date doesn’t align with the expiry date on your work authorization document from Immigration, Refugees and Citizenship Canada (IRCC).
If you have applied for work or study renewal, and your permit expires before the IRCC reaches a decision, you may choose to continue working or studying under the same conditions. However, you must remain in Canada during this time. This is known as “maintained status” (previously called implied status).
The maintained status will remain until a decision is made by IRCC. So, you can work even though your SIN has expired. You can contact the IRCC for more information about maintained status during processing, contact IRCC.
Whenever IRCC authorizes you to continue working in Canada, you have to apply to Service Canada with your new immigration document to update the expiry date on your SIN record. The expiry date on your SIN record must align with the date on your immigration document.
