The Canadian Dental Care Plan (CDCP) renewal window officially opens April 15, 2026, and closes June 1. With more than 6.3 million Canadians enrolled, dental practices across Ontario need a clear action plan to manage the surge of renewal-related questions, verify patient eligibility, and avoid billing disruptions during the transition period.
As of April 2026, the federal government has confirmed that CDCP renewal season will run from April 15 to June 1, 2026. This is the first full renewal cycle since the program's initial rollout, and the stakes are high: patients who miss the deadline lose coverage on June 30 with no retroactive reimbursement. For dental practices in Toronto, Mississauga, Brampton, Markham, Vaughan, and across the Greater Toronto Area, the next seven weeks will require proactive communication with your CDCP patient base.
What Changed: The Renewal Timeline
Health Minister Marjorie Michel confirmed the renewal dates in a formal announcement, urging enrolled Canadians to complete their renewal promptly to maintain uninterrupted coverage. Here is the critical timeline your front desk team needs:
- April 15, 2026: Renewal window opens. Patients can renew online at canada.ca/dental or by calling 1-833-537-4342
- June 1, 2026: Renewal deadline. Applications must be submitted by this date
- June 30, 2026: Coverage expires for patients who have not renewed
- June 2, 2026 onward: Patients who miss the deadline may reapply, but face a coverage gap with no retroactive claims
Pro Tip: Block 15 minutes during your next team morning huddle to walk through these four dates. Print them and post them at the front desk. Every team member who interacts with patients should be able to recite the June 1 deadline without hesitation.
Who Needs to Renew and What They Need
All current CDCP members must renew their coverage during the April 15 – June 1 window. This is not automatic. The renewal process requires patients to re-attest to the following eligibility criteria:
- Income threshold: Adjusted family net income below $90,000 CAD, based on the most recent tax filing
- No private insurance: The patient must confirm they do not have access to private dental benefits
- Canadian residency: Must be a Canadian resident for tax purposes
- 2025 taxes filed: Patients must have filed their 2025 tax return and received their Notice of Assessment from the Canada Revenue Agency (CRA)
That last requirement is the one most likely to trip patients up. Tax filing season overlaps directly with the renewal window, and patients who file late may not receive their Notice of Assessment in time to complete renewal before June 1.
What About Patients Whose Income Changed?
Patients whose adjusted family net income has risen above $90,000 CAD based on their 2025 tax return will no longer qualify. Practices should be prepared for difficult conversations with patients who assumed their coverage would continue. The program uses the most recent tax year data, so a promotion, change in spousal employment, or one-time income event can push a household above the threshold.
Conversely, patients who were previously ineligible may now qualify if their income dropped below $90,000 CAD. These individuals can apply as new members through the standard application process at canada.ca/dental.
The Impact: 6.3 Million Enrollees and Growing
The scale of the CDCP is now impossible for any Canadian dental practice to ignore. The program has approved more than 6.3 million Canadians, and over four million have already received dental care through the plan. Ontario leads all provinces in provider participation, reflecting both the size of the provincial population and the density of dental practices in markets like the GTA.
For practices that have embraced CDCP, the renewal period represents both an administrative challenge and a patient retention opportunity. Patients who successfully renew will continue generating predictable, government-funded revenue for your practice. Patients who lapse create scheduling gaps and may delay care until they can reapply — often returning months later with more complex and costly treatment needs.
Five Steps Your Practice Should Take Before April 15
1. Audit Your CDCP Patient Roster
Pull a list of all patients currently flagged as CDCP beneficiaries in your practice management system. Depending on your software, this may be tracked through insurance carrier codes, billing categories, or custom patient tags. If you have not been tracking CDCP patients separately, now is the time to create that filter.
2. Send Proactive Renewal Reminders
Do not wait for patients to figure this out on their own. Send a targeted communication — email, text, or both — to your CDCP patients informing them that renewal opens April 15 and closes June 1. Include the renewal website (canada.ca/dental) and phone number (1-833-537-4342) directly in the message.
Under Canada's Anti-Spam Legislation (CASL), you can send transactional messages related to an existing business relationship without explicit consent, as long as the communication is relevant to the service you provide. A renewal reminder for their dental insurance falls squarely within this provision.
3. Train Front Desk Staff on Common Questions
Your front desk team will field dozens of renewal-related calls over the next six weeks. Prepare them with clear answers to the most common questions:
- "Do I have to renew?" — Yes, renewal is mandatory. Coverage is not automatic.
- "How do I renew?" — Online at canada.ca/dental or by phone at 1-833-537-4342.
- "I haven't filed my taxes yet." — You will need your 2025 Notice of Assessment. File your taxes as soon as possible to receive it before June 1.
- "What happens if I miss the deadline?" — Coverage ends June 30. You can reapply after June 2, but there will be a gap in coverage.
4. Verify Eligibility Before Scheduling Major Treatment
For CDCP patients with treatment plans spanning the renewal period, verify their renewal status before scheduling major procedures in late June or July. A patient who has not renewed by June 1 will lose coverage June 30, leaving your practice with an uncollectable claim if treatment was performed under the assumption of active benefits.
The Sun Life provider portal — the CDCP's third-party administrator — allows providers to verify patient eligibility in real time. Build an eligibility check into your pre-appointment workflow for all CDCP patients during the May-July window.
5. Update Your CDCP Billing Processes
The updated CDCP Dental Benefit Grids that took effect April 1, 2026, introduced revised fee codes and reimbursement levels. If you have not already updated your billing templates to reflect the new grids, do so immediately. Submitting claims under outdated codes during the renewal transition will create unnecessary rejections and delays.
The Ontario Dental Association (ODA) and Canadian Dental Association (CDA) have both published guidance on aligning practice billing with the updated benefit grids. Check your provincial dental association's member portal for the most current resources.
Pro Tip: Create a shared document or checklist for your billing team that maps the most common procedure codes to their updated CDCP reimbursement rates. Cross-reference against the 2026 ODA Suggested Fee Guide to identify any procedures where CDCP reimbursement falls significantly below your usual fee — and flag those for patient financial discussions.
The Bigger Picture: CDCP and Practice Economics
The CDCP renewal cycle is a useful lens for evaluating how dependent your practice has become on government-funded patients. Practices in areas like Scarborough, Etobicoke, North York, and Brampton — where CDCP enrollment rates tend to be higher — should model what happens to their schedule and revenue if a significant portion of their CDCP patients fail to renew.
This is not an argument against participating in the program. The CDCP has brought over four million Canadians into dental care who were previously going without. That is an enormous public health achievement and a meaningful source of patient volume for participating practices. But prudent practice management means understanding your payer mix and having contingency plans for each segment.
The Personal Information Protection and Electronic Documents Act (PIPEDA) governs how you store and communicate patient insurance information, including CDCP enrollment status. Ensure your team handles renewal-related communications through secure channels, particularly if you are sending messages that reference a patient's insurance status or financial eligibility.
Pro Tip: Run a quick payer mix analysis this week. Calculate what percentage of your monthly production comes from CDCP reimbursements versus private insurance, fee-for-service, and membership plan patients. If any single payer source exceeds 30% of your revenue, consider diversifying your patient acquisition strategy to reduce concentration risk.
