Frequently asked questions

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.
