Quebec Change of Address Service: How the SQCA Works After a Divorce

Divorce almost always means at least one person moves. In Quebec, that move triggers a hard legal deadline most people don't know about: under the Highway Safety Code, you have 30 days to report your new address for your driver's licence and vehicle registration. Miss it and you're technically driving with an invalid licence address — and your RAMQ file, voter registration, and tax correspondence are all pointing at a home you no longer live in.

The good news: Quebec built a single tool that handles most of it in one session. The Service québécois de changement d'adresse (SQCA) lets you notify up to seven government bodies at once, online, for free. Here's exactly how it works, what it covers, and — just as important after a divorce — what it doesn't.

What the SQCA updates in one transaction

The SQCA is a joint service run by the provincial government. One online form pushes your new address to all of these at the same time:

• SAAQ — driver's licence and vehicle registration (this satisfies the 30-day Highway Safety Code requirement)
• RAMQ — health insurance card file and the public prescription drug plan
• Revenu Québec — provincial tax file, Solidarity Tax Credit, and support-payment program correspondence
• Directeur général des élections du Québec (DGEQ) — voter registration
• Retraite Québec — QPP file, Family Allowance, and pension plan correspondence
• Emploi et Solidarité sociale — social assistance files, if applicable
• Public curator / other participating bodies, depending on your file

You complete it once at Québec.ca (search "Service québécois de changement d'adresse"). Have your health insurance card number, driver's licence number, and social insurance number handy — the service uses them to match your identity across the agencies.

The whole thing takes about 15 minutes. Confirmation is on screen; each agency then updates its own records on its own timeline, typically within a few business days.

What the SQCA does NOT cover

This is where post-divorce movers get caught. The SQCA only reaches provincial agencies. It does nothing for:

• Canada Revenue Agency (CRA) — federal tax file, Canada Child Benefit, GST/HST credit. Update separately through CRA My Account or by phone.
• Service Canada / SIN record — a separate federal update.
• Passport — passports don't show an address, so no change is needed, but IRCC correspondence addresses are separate.
• Banks, credit cards, insurers, utilities, Hydro-Québec, your employer, your children's school and daycare, your pension plan administrator — all private or institutional updates you must make one by one.

Think of the SQCA as step one of a two-part move: provincial agencies in one shot, then a manual sweep of everything federal and private. If you're mid-divorce, that manual list is longer than usual — joint accounts, shared insurance policies, and employer benefits all need separating, not just re-addressing. The Quebec After-Divorce Checklist walks through that full sweep in chronological order.

The 30-day SAAQ rule and why it matters more after divorce

The Highway Safety Code gives you 30 days from your move to update the address on your driver's licence and vehicle registration. The SQCA handles this, so the deadline is easy to meet — but after a divorce there are extra wrinkles:

Vehicle ownership transfers are separate. If the divorce assigns a family vehicle to one spouse, an address change doesn't transfer the title. A vehicle registered in both names (or in your ex's name) needs an ownership transfer at an SAAQ service outlet, usually with the divorce judgment or separation agreement in hand. Until that's done, the registration — and any tickets or tolls — still ties you together.

Family Allowance and children's addresses. If you have children, Retraite Québec's Family Allowance file routes payments based on custody arrangements, not just addresses. Update the custody-time split with Retraite Québec directly; the SQCA address change alone won't recalculate anything.

The RAMQ drug plan trap. Divorce often means losing coverage under an ex-spouse's private group drug insurance. You have 30 days from losing that coverage to register for the RAMQ public prescription drug plan — miss the window and you can face a permanent premium surcharge (15% in many cases) when you eventually enroll. The SQCA updates your address with RAMQ, but registering for the drug plan after losing private coverage is a separate step you must initiate yourself.

A sensible sequence for the move

1. Before moving day: open an individual bank account and redirect your pay and any government deposits if you haven't already.
2. Within days of the move: complete the SQCA online — this clears the SAAQ 30-day clock and updates RAMQ, Revenu Québec, DGEQ, and Retraite Québec in one go.
3. Same week: update CRA (My Account → "Change my address"), and if you've lost private drug coverage, register with the RAMQ public plan immediately.
4. Following two weeks: banks, credit cards, insurers (auto and home policies must be split into individual policies), Hydro-Québec, internet, employer HR and benefits, children's school and daycare.
5. If a vehicle changed hands in the divorce: book the SAAQ ownership transfer — bring the judgment or notarized agreement.

The bottom line

The Service québécois de changement d'adresse is genuinely useful — seven agencies, one form, free, 15 minutes. But it covers only the provincial slice of a post-divorce move. The federal updates, the drug-plan registration, the vehicle title transfer, and the untangling of joint accounts all sit outside it, each with its own deadline and its own paperwork.

If you want the full sequence — what to update in the first 30 days, what waits for the divorce certificate, and the letter templates for banks and insurers — the Quebec After-Divorce Checklist lays it all out step by step.
