Once you officially land as a Permanent Resident, your temporary 9-series Social Insurance Number (SIN) becomes invalid. You must apply for a standard permanent SIN (starting with 1, 5, or 7) at Service Canada to ensure your employer’s payroll and CRA tax filings are processed correctly.
Receiving your electronic Confirmation of Permanent Residence (eCOPR) is an exciting milestone, marking the end of your temporary status in the country. However, your transition is not fully complete until you update your records with the federal government. For years as an international student or temporary foreign worker, you likely used a SIN starting with the number 9, which signifies temporary status.
Now that you are a Permanent Resident, that number must be retired. 🔒 Continuing to use a temporary SIN can cause major headaches with the Canada Revenue Agency (CRA) and delay your wages. Securing your permanent Canadian SIN is a straightforward process, but if you encounter legal issues regarding your employment transition, consulting a local law firm from our directory can provide clarity.
Step-by-Step Process for Updating Your SIN in Canada
Whether you reside in Halifax, Winnipeg, or Vancouver, the process is federally managed by Employment and Social Development Canada (ESDC). You have the option to update your profile online, by mail, or in person at your local Service Canada centre.
Step 1: Gathering the Right Documents
To obtain your new permanent SIN, you need proof of your new status. 📄 You must present your signed eCOPR or your physical PR card. You will also need a secondary piece of identification, such as your foreign passport or a provincial driver’s licence from Ontario or Alberta.
Step 2: Applying at Service Canada
The fastest method is visiting a local Service Canada location. If you walk in with your original documents, an agent will process your application on the spot. They will instantly print out a paper document containing your new permanent SIN (starting with a 1, 5, or 7, depending on your province). Plastic SIN cards are no longer issued in Canada.
Step 3: Notifying Your Employer and Bank
Once you have your new number, you are legally obligated to provide it to anyone who needs it for tax or income reporting. 💼 You must give your new SIN to your employer’s HR department so they can update their payroll software. You also need to inform your bank, especially if you hold registered accounts like an RRSP or a TFSA.
How Much Does It Cost to Get a Permanent SIN?
Applying for or updating a Social Insurance Number in Canada is entirely free. Here are the associated cost details to keep in mind for May 2026:
- Service Canada Fee: $0 CAD. The federal government does not charge you to transition from a 9-series to a permanent SIN.
- Third-Party Scams: Beware of websites offering to “speed up” your SIN application for a fee. Only apply directly through the official Government of Canada portal.
- Tax Implications: Failing to update your SIN could result in missed tax credits or delayed refunds from the CRA, indirectly costing you money.
How Long Does the Process Take?
The timeline depends entirely on how you choose to apply. If you apply in person at a Service Canada centre in Toronto or Montreal, you walk out with your new number on the exact same day. If you choose to apply online via the federal web portal, it typically takes up to 15 business days for your new SIN letter to arrive by mail to your Canadian address.
Differences Between Temporary and Permanent SINs
| SIN Type | First Digit | Who Uses It? | Expiration |
|---|---|---|---|
| Temporary SIN | Starts with 9 | International students, temporary foreign workers | Tied to your temporary work or study permit. |
| Permanent SIN | Starts with 1, 5, 7, etc. | Citizens and Permanent Residents | Never expires. Valid for life. |
Frequently Asked Questions (FAQ)
Does my credit score transfer to my new permanent SIN?
Yes, but it is not always automatic. You should contact Canada’s two major credit bureaus, Equifax and TransUnion, to inform them of your new SIN so they can merge your old 9-series credit history with your new file.
Can I keep working while waiting for my new SIN?
Generally, yes. As long as you have received your eCOPR, your right to work in Canada is protected. Simply inform your employer that you are in the process of securing your permanent number from Service Canada.
Do I need to notify the CRA about my new SIN?
Service Canada and the CRA communicate with each other. When you file your next income tax return using your new permanent SIN, the CRA will link your past tax history from your old 9-series number to your new one.
What happens to my old 9-series SIN?
Your old temporary SIN is officially deactivated by the government. You should safely shred any documents containing the old number once the transition is complete to prevent identity theft.
