Is the Ontario Autism Program underfunded?
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**. [FAO, Ontario Budget 2026] This gap is the primary driver of the perpetual 89,799+ child waitlist.
