Public / OHIP-Covered Assessment
Private Psychological Assessment
A private assessment may speed up diagnosis and OAP registration, but cost and wait estimates need current local verification. Do not count on legacy interim funding for new registrations.
A quick eligibility check for the Ontario Autism Program.
Yes, as long as the assessment is completed by a qualified professional (registered psychologist with the College of Psychologists of Ontario, or a physician). The diagnosis must meet DSM-5 criteria for Autism Spectrum Disorder.
Private psychological assessment fees vary by clinician, region, and complexity. Some extended health insurance plans cover a portion. Paediatrician assessments may be OHIP-covered when the clinician is qualified to diagnose. Check with your insurer and ask about sliding-scale fees.
A common strategy is to get a private assessment quickly for OAP registration while keeping the public referral active. The public assessment provides a comprehensive multidisciplinary evaluation that can identify co-occurring conditions and inform the OAP service plan.
