Canadian Dental Care Plan (CDCP) - a 2026 guide for Ontario dental clinics

What the CDCP is - and why your clinic feels it

The CDCP is a federally funded plan, administered by Sun Life, that helps cover the cost of dental care for eligible Canadian residents without private insurance. For clinics, the practical effect is a steady stream of patients who previously delayed care - which means more new-patient exams, more treatment planning conversations, and more administrative load at the front desk. The clinics that handle it smoothly treat CDCP as an operations project, not just a billing change.

Participating and billing through Sun Life

Oral health providers can bill the CDCP on a claim-by-claim basis. By submitting a claim, you agree to the CDCP Billing Agreement, to bill Sun Life directly, and to limit out-of-pocket costs for the patient. Both electronic (EDI) and paper claims are accepted. Before treatment, confirm coverage with an EDI estimate, the Sun Life CDCP Coverage Look-up tool, or the provider contact centre - so the patient knows their portion before they sit in the chair. The Ontario Dental Association's CDCP FAQ is a useful Ontario-specific reference for your team.

• Verify eligibility and coverage before every CDCP appointment
• Bill Sun Life directly; do not balance-bill the patient above their co-payment
• Give patients a written estimate of their share before treatment
• Keep CDCP Explanation of Benefits (EOB) records with the patient file

What changed in April 2026

The plan continues to evolve, so a static binder will fall out of date. As of April 1, 2026, all desensitization services billed to the CDCP require preauthorization, and certain complete immediate dentures no longer need preauthorization (they now fall under the same frequency limits as other complete dentures). Build a habit of checking the current CDCP Dental Benefit Grids and billing codes before submitting, rather than relying on last year's notes.

Coordinating the CDCP with Ontario programs

Many patients are covered by both the CDCP and an Ontario program such as Healthy Smiles Ontario, ODSP, or Ontario Works. In those cases the CDCP is the primary payer: submit to Sun Life first, then submit to the provincial payer (Accerta) as the second payer within 30 days of the service date. Getting the order wrong is the most common reason CDCP claims get stuck. The Government of Canada coordination-of-benefits fact sheet for Ontario lays out the sequence in detail.

The operational side most clinics underestimate

More covered patients means more scheduling, more verification, and more recordkeeping - which is exactly where understaffed front desks break down. If your admin team is already stretched, this is the moment to fix it. Prime DMS helps Ontario clinics right-size their front-desk and administrative hiring and tighten the operational systems - scheduling, verification workflows, and supply and inventory planning - that a busier patient base demands.
