How many children are on the Ontario autism waitlist in 2026?

As of December 2025, **88,175 children are registered with the Ontario Autism Program**. [FOI] However, only **20,666 (23.4%)** have an active Core Funding Agreement. This represents approximately 280% growth in the waitlist since 2019, with over 67,000 children still waiting for essential funding.

Source: FOI Data Dec 2025, FAO Report 2024

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 88,175+ child waitlist.

Data Analysis

Where Is the Real Number?

Ontario reports 88,175 children on the autism waitlist. That figure is accurate, but it does not count children waiting for diagnosis, children who aged out without service, or those never diagnosed.

88,175

Children registered with the Ontario Autism Program.

Known waiting

67,509

Children still waiting for core services funding.

Outside the count

Fair comment on a matter of public interest. Every figure in this analysis is sourced. Published government data is presented as-is. Estimates are clearly labelled with confidence levels and ranges. Government positions are included where they exist. No motive is imputed. Legal basis: fair comment + justification (Grant v. Torstar, 2009 SCC 61).
Key Findings
  • Ontario's official count of 88,175 registered children is accurate but incomplete — it excludes children awaiting diagnosis, those who aged out, and those never diagnosed.
  • At least 6,113 children were waiting for diagnosis at just 5 hubs (Trillium FOI, Mar 2024). The province does not publish a centralized diagnostic waitlist.

In Briefas of December 2025

As of December 2025, Ontario reports 88,175 children registered with the Ontario Autism Program (OAP). However, this figure excludes children awaiting diagnosis (at least 6,113 at five hubs alone), children who aged out at 18 without receiving services, and undiagnosed children. The true number of affected children is significantly higher than the official count.
