How to Get a SIN Number in Canada as a Newcomer
Your Social Insurance Number is the key to working, paying taxes, and accessing benefits in Canada. It's free, and applying in person gets it done the same day. Here's exactly what to bring and where to go.
What is a SIN?
A Social Insurance Number (SIN) is a unique 9-digit number issued by Service Canada. You need it to work in Canada, file taxes, open certain bank accounts, and receive government benefits. Without one, no employer can legally put you on payroll.
It's free — there is no application fee, ever. Anyone charging you for a SIN is running a scam.
Who can get one?
- Permanent residents — bring your PR card, or your Confirmation of Permanent Residence (COPR) if you landed less than a year ago, plus your passport.
- Work permit holders — bring your valid work permit plus passport. Your SIN will expire when your permit does; you'll renew it when you renew the permit.
- Study permit holders — only if your permit says you "may work" or "may accept employment." Bring the permit plus passport.
- Children 12 and older can get their own SIN. For kids under 12, a parent or guardian applies on their behalf.
How to apply (3 ways)
1. In person — fastest
Visit any Service Canada Centre with your original documents. You'll usually walk out with your SIN confirmation letter the same day. No appointment needed at most locations, but check online first — some offices are walk-in only, others take bookings. This is the method we recommend for newcomers.
2. Online
Service Canada has an online SIN portal, but eligibility is limited — it generally works for permanent residents with a COPR issued within the last year. You'll upload scans of your documents. Processing takes longer than in-person.
3. By mail
If you live more than 100 km from a Service Canada office, you can mail your application with original documents (not photocopies) to the Social Insurance Registration Office in Bathurst, NB. Use tracked mail. Expect 20+ business days.
Documents checklist: primary document proving status (PR card, COPR, or work/study permit) + secondary ID (passport). All documents must be originals — photocopies are not accepted. Make sure your name matches across all documents to avoid delays.
Protect your SIN
Your SIN is the master key to your identity in Canada. Share it only when required: for a job (employer payroll), taxes, bank accounts, and government benefits. Nobody else needs it — not landlords, not phone stores, not "verification" callers.
Common scam: someone calls claiming to be Service Canada or the CRA, saying your SIN is "suspended" or "compromised" and demanding payment or personal details. This is always fraud — the government never operates this way. Hang up.
What if you lose it?
Your SIN itself never changes — only the confirmation letter can be replaced. Visit Service Canada with your documents and they'll issue a new letter. There's no fee. And no, you can't get a new SIN number because the old one was "compromised" — that only happens in rare cases of proven identity theft, decided by Service Canada.
Next in your first 14 days: with your SIN in hand, open a bank account and get a phone plan. Then continue with the full 14-day checklist.
