How much does a private autism assessment cost in Ontario?

Private autism assessments in Ontario typically range from $2,500 to $4,500 depending on the clinician, region, and complexity of the assessment.

Is the Ontario Autism Program underfunded?

Verified

Yes. The Financial Accountability Office (FAO) determined that $1.35 billion annually is needed to serve all registered children at 2018-19 service levels. The 2026-27 Ontario Budget allocated $965 million, leaving an estimated $385M+ annual shortfall. This gap is the primary driver of the perpetual 91,974+ child waitlist.

How much does Ontario fund for autism treatment?

Verified

Core Clinical Services funding ranges $6,600-$65,000 per year based on age/needs (with a total OAP budget of $965M for 2026-27, up from $779M in 2025-26, per the Ontario Budget tabled March 26, 2026). This is direct funding—families choose public or private providers. However, intensive ABA therapy can cost up to $95,000 USD/year (2020 US cost estimate cited in FAO 2020 report; Canadian costs vary), leaving significant out-of-pocket gaps.
