Getting Your SIN Number as a Newcomer to Canada 2025

Updated March 2025 · bremo.io

Your Social Insurance Number (SIN) is one of the first things you need when you arrive in Canada. You cannot legally work, receive government benefits, or open certain financial accounts without it. Here is everything newcomers need to know about getting their SIN.

What Is a SIN?

A Social Insurance Number is a 9-digit number issued by Employment and Social Development Canada (ESDC). It is used to:

• Work legally in Canada (employers need your SIN for payroll and tax purposes)
• File income taxes with the Canada Revenue Agency (CRA)
• Access government programs (EI, CPP, OAS)
• Open registered investment accounts (TFSA, RRSP, RESP)
• Apply for certain government benefits

Who Can Get a SIN

• Canadian citizens: Eligible at birth — apply anytime
• Permanent residents: Eligible immediately upon landing
• Work permit holders: Eligible — SIN begins with 9 and has an expiry date linked to your permit
• Study permit holders: Eligible if authorized to work (co-op, on-campus, or if permit has open work authorization)
• Protected persons / Convention refugees: Eligible
• Visitors or tourists: Not eligible

How to Apply for Your SIN

Option 1: In Person at Service Canada

Walk into any Service Canada Centre. This is the fastest method — you typically receive your SIN on the same day.

What to bring:

• Primary identity document: passport, or PR card / COPR (Confirmation of Permanent Residence)
• Secondary identity document if requested: foreign driver's licence, marriage certificate, birth certificate
• Your Canadian address

No appointment is needed at most Service Canada offices. Wait times are typically 15–60 minutes.

Option 2: Online Application (My Account)

IRCC/ESDC has expanded online SIN application options. You will need:

• A GCKey or Sign-In Canada account
• Digital copies of your identity documents
• A Canadian mailing address to receive your SIN confirmation letter

Online processing typically takes 5–10 business days.

Option 3: By Mail

You can mail your application with certified copies of documents. Not recommended — takes the longest and carries risk of document loss.

SIN for Permanent Residents

When you land as a permanent resident, you receive a COPR (Confirmation of Permanent Residence). Take this to Service Canada along with your passport to get your SIN. PR SINs do not expire.

SIN for Temporary Residents (Work/Study Permit Holders)

Temporary SINs (beginning with 9) have an expiry date. This expiry matches the expiry on your immigration document. When your permit is renewed:

• You must update your SIN expiry date at Service Canada
• Bring your new permit to any Service Canada location
• Your SIN number stays the same — only the expiry date changes

If your SIN expires and you have not renewed it, employers cannot legally pay you and your tax filings will be affected.

Protecting Your SIN

Your SIN is sensitive personal information. Protect it:

• Never carry your SIN card in your wallet
• Only share your SIN with employers, financial institutions, and government agencies
• Do not share your SIN via email or text unless the channel is secure
• If your SIN is stolen, report it immediately to ESDC at 1-800-206-7218

SIN and Your Taxes

Your SIN links all your Canadian tax filings. Employers report your income to CRA using your SIN on T4 slips. When you file your annual T1 income tax return, you must include your SIN. Having a SIN from the start of your employment year ensures all your income is properly reported and you receive accurate tax refunds.

Opening Financial Accounts With Your SIN

Once you have your SIN, you can open:

• TFSA (Tax-Free Savings Account) — the best savings vehicle for newcomers
• RRSP (Registered Retirement Savings Plan)
• Investment accounts at brokerages
• Chequing and savings accounts (some banks need your SIN, others just recommend it)

Your 2025 TFSA contribution room starts accumulating from the year you become a Canadian resident and turn 18. Even as a temporary resident, you build TFSA room for every year you are resident in Canada — opening a TFSA early means more room later.

Children's SINs

Children can get SINs too. You'll need this if you:

• Open an RESP (Registered Education Savings Plan) for your child
• Apply for the Canada Child Benefit (CCB)
• Have a child who starts working

Apply at Service Canada with the child's birth certificate or passport and your own ID.
