Update Your Passport and SIN After Divorce in Canada

Your Social Insurance Number and Canadian passport are federal documents — they follow the same process regardless of which province you live in. But the order in which you update them matters, especially if you're also changing your name.

Step 1: Update Your SIN Record (Do This First)

Your 9-digit SIN number doesn't change after divorce. But if you've changed your name, Service Canada must update their records to link your old name to your new one. This prevents mismatches when employers report your income to CRA or when you apply for other federal services.

How to apply:

• Online: Through My Service Canada Account. Processed within 5 business days.
• In person: At any Service Canada Centre. Processed immediately.

Documents required:

• Your Certificate of Divorce (or Change of Name Certificate if you did a formal name change)
• Your current provincial photo ID
• Proof of current address

Cost: Free

Why do this first: Your updated SIN record confirms your legal name in the federal system. When you apply for a new passport, your SIN record and your provincial ID should both show your current name — mismatches trigger verification delays.

Step 2: Apply for a New Passport

You cannot "update" a Canadian passport. A name change requires a completely new passport application, even if your current passport hasn't expired.

How to apply:

• Complete the standard Adult General Passport Application (Form PPTC 153)
• Submit at a Service Canada Centre or passport office

Documents required:

• Completed application form
• New passport photos meeting current specifications
• Your current passport (it will be cancelled)
• Certificate of Divorce (or Change of Name Certificate)
• Your updated provincial photo ID (in your new name)
• The standard passport fee

Cost:

• 10-year adult passport: $160
• 5-year adult passport: $120
• Express processing (10 business days): add $50
• Urgent processing (next business day, in person only): add $110

Standard processing time: 10 to 20 business days

If you're not changing your name: You don't need a new passport. Your existing passport remains valid until its expiration date. Your marital status isn't displayed on a Canadian passport.

The Name Change Exception

If you're simply reverting to your birth name (the name on your original birth certificate), the Certificate of Divorce serves as your name-change proof. You don't need a separate Change of Name Certificate from your provincial Vital Statistics office.

If you're adopting an entirely new name — one you've never legally held — you need the formal Change of Name Certificate from Vital Statistics in addition to the Certificate of Divorce.

Common Mistakes That Delay Processing

Submitting before your SIN is updated. If Service Canada's system still shows your married name but your application uses your birth name, it creates a mismatch that requires manual verification.

Not having your provincial ID updated first. The passport application requires a valid provincial photo ID in your current legal name as supporting identification. If your driver's licence still shows your married name, get it updated at your provincial licensing office before submitting the passport application.

Forgetting to cancel your old passport. If you submit a new application without surrendering your current passport, processing stops until you provide it. Include it with your application.

The Correct Full Sequence

For Canadians in Prince Edward Island (or any province), the most efficient update order is:

1. SIN (free, immediate or 5 days) → establishes your name in the federal system
2. Provincial driver's licence ($20 at Access PEI) → gives you photo ID in your new name
3. Provincial health card (free at Health PEI) → can be done same day as licence
4. Passport ($160, 10–20 days) → requires both updated SIN and provincial ID

Running these in parallel causes rejected applications. Running them in sequence — even just a few days apart — ensures each agency accepts the prior update as supporting evidence.

The Prince Edward Island After-Divorce Checklist includes a timeline tracker that sequences all federal and provincial ID updates, so you don't waste money on rejected applications or duplicate processing fees.
