If you are already enrolled in the Canadian Dental Care Plan, keeping your coverage active requires one important step each year: renewing on time. Missing a CDCP renewal deadline does not just mean a gap in coverage. It can mean dental treatments you received before you renewed are not covered at all, leaving you with an unexpected bill.
This guide walks through how to renew the Canadian Dental Care Plan, the documents required, the three ways to renew, and what happens if your income changed this year or if you never received a renewal letter.
Why CDCP Renewal Is Required Every Year
The Canadian Dental Care Plan is not a one-time application. Enrollment must be renewed annually because your eligibility is tied to your income and your insurance status, both of which can change from year to year.
Each time you renew CDCP, the government reassesses your adjusted family net income using your most recent tax return and confirms that you still do not have access to private dental insurance. If either of those things has changed, your coverage level or eligibility may change as well.
This is why renewing on time matters. A late Canada dental plan renewal can result in a gap where treatments you received are not covered retroactively. Your coverage only applies from the date your renewal is confirmed, not from the start of the coverage period.
When to Renew Your CDCP
CDCP renewal opens after you have filed your taxes and received your Notice of Assessment from the Canada Revenue Agency. You do not need to wait for an invitation letter to begin the process.
The government sends renewal reminders by mail to current members, but these letters sometimes arrive late or get missed. Do not rely on receiving a letter as your cue to act. Mark the renewal window in your calendar and initiate the renewal process as soon as your taxes are filed and your CRA assessment is available.
Key Dates for CDCP Renewal
Knowing the exact dates removes any guesswork from the process. Based on the current renewal cycle:
• Renewal window opens: After you file your taxes and receive your CRA Notice of Assessment, typically mid-April
• Renewal deadline: June 1, 2026, the confirmed cutoff for the current renewal period
• New coverage period: July 1, 2026 to June 30, 2027
• What triggers eligibility review: Your adjusted family net income as reported on your CRA Notice of Assessment
These dates are confirmed by CTV News and the Government of Canada’s CDCP page. The renewal window and deadline follow this same annual pattern each year, so checking Canada.ca directly is the safest way to confirm current dates.
If you miss the June 1 cutoff, your coverage does not simply carry over. You lose coverage from July 1 onward and will need to submit a new application rather than a simple renewal, which means a longer wait before coverage resumes.
What You Need Before You Renew CDCP
Gather these details before starting your renewal to avoid stopping partway through:
• Social Insurance Number (SIN)
• CDCP client number, found on your CDCP member card or any government letter about your plan
• Your most recent CRA Notice of Assessment, which confirms your income for the previous tax year
• Current contact information: address, phone number, and email address
• Details of any other government dental coverage you may use, if applicable
If you have misplaced your CDCP client number, contact Service Canada at 1-833-537-4342 and they can retrieve it for you before you begin.
3 Ways to Renew Your CDCP
Option 1: Renew Online
The fastest way to complete your renewal is through the Government of Canada’s online portal. Visit the CDCP renewal page on Canada.ca using an updated browser such as Chrome, Firefox, Safari, or Edge. You will be prompted to enter your SIN, CDCP client number, and updated personal details. The process typically takes under 10 minutes.
Option 2: Renew Through My Service Canada Account
If you already have a My Service Canada Account (MSCA), you can renew directly through your account dashboard. Log in at canada.ca/my-service-canada-account, navigate to the Canadian Dental Care Plan section, and select “Renew my coverage.” This option is convenient if you already use MSCA for other government benefits. If you do not have an MSCA account, you can register on the same page, verifying your identity using your SIN and personal information.
Option 3: Renew by Phone
For members who prefer to speak with someone or do not have easy online access, renewal is also available through an automated phone service. Call 1-833-537-4342 (TTY: 1-833-677-6262). The service is available at any time. Have your SIN and CDCP client number ready before calling.
What Happens After You Renew CDCP
Once your renewal request is processed, you will receive a confirmation letter from the government outlining your new coverage dates and your coverage percentage based on household income.
You do not need to wait for a new physical card. Your existing CDCP member card remains valid, and you can bring either the card or your confirmation letter to dental appointments to confirm your coverage. Most registered CDCP dental clinics can also verify your status directly when you check in. It is a good idea to bring your confirmation letter to your first appointment after renewal so your clinic can update their records for the new coverage period.
What Happens If Your Income Changed This Year
Because renewal is based on your most recent tax return, a change in household income can affect how much coverage you receive in either direction.
If your income went down this year, you may qualify for a higher coverage percentage than you had in the previous period. Renewing on time ensures you receive the updated benefit level from the start of the new coverage period.
If your income increased and now falls above the $90,000 household threshold, you will no longer be eligible for the plan, and the government will notify you of this when your renewal is assessed.
If your income increased but remains below the threshold, your coverage percentage may shift. For example, moving from below $70,000 to between $70,000 and $79,999 changes your coverage from 100% to 60% of the government fee schedule.
What Happens If You Miss the CDCP Renewal Deadline
Missing the deadline is not the end of your coverage permanently, but it does create a gap that can be costly. If you renew after the deadline, your new coverage begins from the date your renewal is processed, not from the start of the new coverage period. Any treatments you received between the deadline and your renewal date will not be covered retroactively, meaning you would be responsible for the full cost of that treatment.
If you missed the deadline and are unsure of your options, contact Service Canada at 1-833-537-4342. In some cases, late renewals may still be accepted depending on timing and circumstances.
What If You Never Received a Renewal Letter
Renewal reminder letters are sent by mail to the address on file with the government. If you moved, changed your contact information, or the letter was simply missed, you may not receive it. Not receiving a letter does not mean you are not required to renew, and it does not extend the deadline. The responsibility to renew on time rests with the member.
To update your mailing address or contact details, log in to your My Service Canada Account or call 1-833-537-4342. Keeping your contact information current ensures you receive renewal reminders, confirmation letters, and other important updates about your coverage.
Common CDCP Renewal Mistakes to Avoid
Waiting for the letter before starting. Renewal letters can arrive late or get lost in the mail. Renew as soon as your CRA Notice of Assessment is available rather than treating the letter as the starting signal.
Missing the June 1 deadline. This is the single most costly mistake. Late renewal means no retroactive coverage from July 1. Set a calendar reminder for mid-April and act as soon as your Notice of Assessment arrives.
Using an outdated browser for online renewal. The government’s online portal requires an updated browser to function correctly. If you encounter errors, try switching browsers before calling the phone line.
Not updating your contact information. If your address, phone, or email has changed since you last renewed, update it before submitting your renewal so future correspondence reaches you.
Assuming coverage continues automatically. The CDCP does not auto-renew. Each year requires an active step on your part before the cutoff.
Using Your CDCP After Renewal
Once your renewal is confirmed, booking your next dental appointment is straightforward. You bring your CDCP member card or confirmation letter, and your registered dentist handles the billing directly with the government for the covered portion.
A dental cleaning and exam is one of the most commonly covered CDCP services and a practical first appointment after renewing.
