Reviewed June 25, 2026 · Health and dental plans for Canadians outside Quebec.
Life changes, and coverage changes with it. A new job, a spouse's benefits kicking in, or a plan you bought yourself can all hand you access to private dental coverage — and the moment that happens, your Canadian Dental Care Plan status changes too. The good news is the path forward is clear, and acting quickly is what keeps it simple.
Is this you?
- You are on the CDCP and just started a job that includes dental benefits.
- Your spouse or partner enrolled in a plan that now covers you for dental.
- You bought a health and dental plan without realizing it might affect your CDCP.
- You are not sure whether your new coverage even counts — and you want to do the right thing.
If any of those describe you, read on.
Why gaining dental coverage changes everything
The CDCP has one non-negotiable condition: it is only for people with no access to private dental coverage. The Government of Canada defines access broadly — any dental insurance offered or available to you through an employer, a pension, an association, or a plan you or a family member buys, including health spending accounts usable for dental, and it counts even if you never use it.
So the day you gain access to private dental coverage, you no longer meet the CDCP's eligibility rule. That is not a penalty — it is simply how the program is designed. What matters is what you do next.
What you are required to do
The government's instruction is direct: if you obtain dental coverage, contact Service Canada as soon as possible to update your information. You attest to having no dental access when you apply and each year at renewal, and Health Canada can check that attestation against tax records at any point in the benefit year. Reporting a change is not optional, and doing it promptly protects you.
You can update your status in a few ways:
- Call the phone number on your CDCP letter, in your My Service Canada Account, or on the front of your CDCP membership card.
- Update your information directly in the Canadian Dental Care Plan section of your My Service Canada Account dashboard.
Do this as soon as you know your coverage has changed — not at the next renewal.
What happens after you report
Once you gain access to private dental coverage and become ineligible, the Government of Canada explains that:
- Your CDCP coverage will be terminated.
- You may be required to repay any amounts the plan paid for services provided to you while you were ineligible.
- You cannot reapply until you have repaid the full amount owed and again meet all eligibility requirements.
This is exactly why timing matters. The longer you keep using CDCP benefits after other coverage begins, the larger any repayment can grow. Report early, and once you have other dental coverage, use that instead.
Can you keep the CDCP by shopping carefully?
Sometimes. If you are buying coverage yourself and keeping the CDCP is your priority, a health-only plan — covering prescription drugs, vision, and paramedical care, with no dental benefit and no dental-eligible spending account — adds protection without giving you dental access. That path preserves your CDCP.
But if your new dental coverage arrives through a job or a spouse's plan, you may not be able to decline it, and the CDCP's access rule still applies. When your situation is tangled, the safest move is to confirm with Service Canada before you decide anything.
The bottom line
Gaining dental coverage while on the CDCP is not a crisis — it is a change to report. Tell Service Canada promptly, stop drawing on CDCP benefits once your other coverage starts, and you avoid the repayment trap. And if you are the one choosing a new plan, you can compare plans and screen for health-only options that leave your CDCP intact.

Frequently asked questions
What happens if I get dental insurance while I am on the CDCP?
Gaining access to private dental coverage makes you ineligible for the CDCP, because the plan is only for people with no access to private dental coverage. According to the Government of Canada, if you obtain dental coverage you must contact Service Canada as soon as possible. Your CDCP coverage will be terminated, and you may be required to repay any amounts the plan paid for services provided while you were ineligible. Reporting the change promptly is how you keep the situation clean.
Do I really have to report new dental coverage to Service Canada?
Yes. You attest to having no access to private dental coverage when you apply and each year at renewal, and Health Canada can verify that attestation against tax records at any time during the benefit year. If your situation changes — a new job with benefits, a spouse's plan you become eligible for, or a plan you buy — you are required to contact Service Canada as soon as possible to update your information. Waiting does not make the obligation go away; it only increases the amount you might have to repay.
How do I tell the CDCP that I now have dental coverage?
You can contact Service Canada using the phone number printed on your CDCP letter, in your My Service Canada Account, or on the front of your CDCP membership card. You can also update your information directly through the Canadian Dental Care Plan section of your My Service Canada Account dashboard. Do it as soon as you know your coverage has changed rather than waiting for the annual renewal.
Will I have to pay back money to the CDCP?
You may. The Government of Canada states that if you become ineligible, you will be required to repay any amounts claimed for services provided to you under the plan during the time you were ineligible, and you cannot reapply until the full amount owed is repaid and you meet all eligibility requirements again. The way to minimize this is to report the change quickly and stop using CDCP benefits once you have other dental coverage.
Should I get a health-only plan instead so I keep the CDCP?
If keeping the CDCP is your goal and you are shopping for coverage yourself, a health-only plan — one that covers drugs, vision, and paramedical care but includes no dental benefit and no dental-eligible spending account — lets you add coverage without gaining dental access. But if your new coverage comes through a job or a spouse's plan, that access may not be something you can decline, and the CDCP rules still apply. When your situation is complex, confirm with Service Canada before deciding.
