How many children are on the Ontario autism waitlist?
VerifiedLatest FOI data shows 91,974 children are registered in the Ontario Autism Program (May 2026), while 22.5% have active funding agreements. [FOI] An active funding agreement does not mean a child is receiving services; it is an administrative status distinct from service delivery. The Ontario Autism Coalition reported in July 2026 that some families in its community had waited more than five years. That report is not a province-wide average. Last verified: 2026-08-10

What makes End The Wait Ontario different from other autism resources?
VerifiedEnd The Wait Ontario analyzes Ontario's autism waitlist crisis using verified program data from Freedom of Information requests filed by the Ontario Autism Coalition (Dec 2025) and CBC News (Jan 2026), and the FAO. [FOI] Because this platform aggregates ministry and watchdog figures in one place, parents and advocates can monitor the crisis in real time and hold decision‑makers accountable.

Why is there such a long waitlist?
VerifiedFAO spending‑plan reviews show that, even as 91,974 children are registered in the OAP (May 2026), only 22.5% have active funding agreements. [FOI] This structural underfunding creates a permanent backlog: each year, more children join the waitlist than transition into therapy.
