How many children are on the Ontario autism waitlist in 2026?
VerifiedAs of May 13, 2026, 91,974 children are registered with the Ontario Autism Program. However, only 20,711 (22.5%) have an active Core Funding Agreement. This represents ~300% growth in registrations since 2019, with 71,263 children still waiting for essential funding.

Is the Ontario Autism Program underfunded?
VerifiedYes. 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.
