Getting Your Canadian Social Insurance Number: A Guide for Brits
The Social Insurance Number, or SIN, is a nine-digit number issued by Service Canada that identifies you for employment, tax and government benefits purposes. It's Canada's equivalent of your UK National Insurance number.
Who can apply
You can apply if you have a valid work permit, a study permit with work authorisation, permanent resident status, or Canadian citizenship. If you're in Canada on an IEC (International Experience Canada) working holiday visa, you're eligible and should apply as soon as you arrive.
How to apply
Temporary vs permanent SINs
If you're in Canada on a temporary visa, including a working holiday, your SIN begins with the number 9. This temporary SIN carries an expiry date tied to your work or study permit. If your permit is renewed or extended, you need to update your SIN record with the new expiry date at a Service Canada Centre, otherwise it can cause issues with payroll and tax filing. If you later become a permanent resident or citizen, you can apply for a permanent SIN at that point.
Key Takeaways
- Apply online (about 5 days) or in person (same day) at a Service Canada Centre. Both are free.
- Bring your passport and your work or study permit.
- Temporary SINs start with 9 and expire with your permit. Update it if your permit is renewed.
- Give it to your employer before your first payslip and to your bank when opening a TFSA or RRSP.
Frequently Asked Questions
Do I need a SIN to open a Canadian bank account?
Most banks will open a basic account with your passport and immigration documents alone, but you'll need your SIN for any registered product like a TFSA or RRSP, so getting it early is worth it regardless.
What if I can't get to a Service Canada Centre right away?
Apply online instead. It takes a few extra days compared to in person, but doesn't require a visit, and some airports also offer in-person SIN service during peak arrival periods.
