Public diagnosis wait: 12-24 months (up to 30+ in some regions). Private diagnosis wait: 2-6 months ($2,000-$4,000).
Diagnosis is required for OAP registration. The diagnosis wait effectively adds to the 5+ year OAP wait, creating a 7-9 year total wait from initial concern to services.

A confirmed autism diagnosis is required to register with the Ontario Autism Program. Without one, your child cannot even begin the 5+ year OAP waitlist, meaning the diagnosis wait itself adds to the total delay from initial concern to receiving services.
Ask your family doctor for a referral to a hospital-based developmental clinic or autism assessment team. Wait times are 12-24 months. Coverage requires a valid Ontario health card.
Contact a registered psychologist or psychological associate who specializes in autism assessment. Costs range from $2,000-$4,000 with wait times of 2-6 months. Search the College of Psychologists of Ontario directory to find qualified providers.
Many families don't realize the diagnosis bottleneck means a total wait of 7-9 years from the time a parent first raises concerns to when a child receives services. The OAP's 5+ year queue doesn't begin until after the diagnosis, and a diagnosis doesn't happen instantly either.
Families who can afford private assessments ($2,000-$4,000) bypass the 12-24 month public wait. This creates a two-tiered system where children from higher-income families get on the OAP waitlist sooner, giving them a meaningful advantage in accessing services during the critical 0-6 developmental window.
