How to get your SIN (Social Insurance Number) in Canada: quick guide | ImmigraCan

The SIN (Social Insurance Number) is the Canadian equivalent of a CPF — but even more important. Without it, you can't be hired, receive a salary, file taxes, open a full bank account (some accounts), receive government benefits, or study in many programs.

Who needs it

Everyone who will work, study, or receive benefits in Canada:

• Canadian citizens
• Permanent residents (PR)
• Temporary residents with work authorization (work permit or study permit with work rights)

Where and how to get it

In person (the fastest — issued on the spot):

1. Go to a Service Canada Centre — find the nearest one at servicecanada.gc.ca
2. No appointment needed at most offices
3. Bring your documents (list below)
4. Fill out the SIN application form (also available on-site)
5. The agent checks your documents, generates your SIN on the spot, and hands it to you on paper

Online (for PR, slower — 20 business days):

1. Access My Service Canada Account
2. Upload your documents
3. Wait for a letter with your SIN by Canada Post

Required documents

All applicants:

• Primary identity document (one of these):
• Passport + your status/registration in Canada
• Canadian birth certificate (if applicable)
• PR Card
• COPR (Confirmation of Permanent Residence)
• Valid work permit
• Study permit with a work authorization annotation

Newcomers from another country also need:

• Foreign passport
• Proof of status in Canada (work permit, study permit, COPR)

Important deadlines

• Without a SIN, you can't be paid legally — your employer will ask for it on day 1
• You have 3 days after starting work to give your SIN to your employer (a tax rule, though it doesn't block hiring)
• SIN doesn't expire for PRs/citizens
• A temporary resident's SIN expires when their permit expires — numbers starting with 9 = temporary
• Renewal: automatic when you renew your work/study permit

SINs starting with "9" (temporary)

If you have a work permit or study permit, your SIN starts with 9. This means:

• Your employer needs to renew your documents along with you
• When your permit expires without renewal, your SIN "dies" (you can't work)
• When you become a PR, your temporary SIN stops being valid — you get a new SIN (starting with a different digit)

Lost your SIN — what to do

• Do not apply for another SIN. The number is for life (no duplicates are issued).
• Yes, you can request a written SIN confirmation at Service Canada (free, in person)
• Keep your SIN in a safe place. Do not carry the paper in your wallet daily — risk of identity theft

Security precautions

• Never give out your SIN by phone, email, or an unsecured website — scammers pose as the CRA
• An employer can legitimately ask for your SIN, but only after you're hired. Refusing to give it during an interview is your right
• Landlords cannot require a SIN to rent an apartment (it's illegal in several provinces)
• Banks and some services may ask for a SIN, but only give it out when truly necessary (bank account, taxes)

Typical step-by-step (day 1 in Canada)

1. You arrive at the airport, go through CBSA, get your entry stamp
2. Confirm your work permit or COPR was printed correctly
3. Head to your hotel/initial accommodation
4. Day 2: research the nearest Service Canada Centre
5. Day 2 or 3: go to Service Canada with your passport + work permit, leave with a paper SIN
6. Day 3–4: with SIN in hand, open a bank account
7. Day 5+: start applying for jobs, showing legal capacity to work

Frequently asked questions

Do I need a Canadian address to apply for a SIN?
No. Some offices ask for the address where you're staying (even a hotel), but it's not a blocker.

Can my spouse (dependent with open work permit) apply for a SIN?
Yes, same process, with their own work permit.

Do young children need a SIN?
Not to work (obviously), but yes if you want to receive the Canada Child Benefit (CCB) for them.

Can a student with a study permit but no work authorization get a SIN?
Yes, but only if the study permit has the on/off-campus work authorization noted. If it doesn't, you have to apply for that authorization on canada.ca first.

Next steps

• After your SIN and bank account, the next step is a health card (varies by province)
