Local service guide
This guide separates province-wide cost and wait context from the local provider list. Local provider records are not an endorsement or a promise of intake.
Regional wait figures are not substituted for the Ontario-wide wait shown in this guide. Check each provider directly for current intake.

This is not a complete directory. Search AccessOAP for the full list of approved providers in your area.
Review the current registration steps at accessoap.com. Once invited and assigned a Childhood Budget, ESDM delivered by a qualified therapist may be an eligible expense; confirm the current rules directly.
Look for therapists with ESDM certification through the University of California Davis MIND Institute or similar certified training programs. In Ontario, certified providers are primarily found in research settings (McMaster, UOttawa) and select private clinics.
Verify with your AccessOAP coordinator that the provider and service format qualifies for Childhood Budget reimbursement. Ask the clinician to explain fit, goals, evidence, and how progress will be monitored.
