| 91,974 children were registered with the OAP as of May 13, 2026 (MCCSS FOI via OAC · May 2026). 20,711 hold an active Core Funding Agreement; 71,263 do not — a gap of 77.5%. | MCCSS Ontario Autism Program figures, May 13, 2026, obtained by the Ontario Autism Coalition under Freedom of Information · May 13, 2026 |

MCCSS FOI via OAC · May 2026 · May 13, 2026 · Review the source
Definitions
- Registered means a child or youth has an open file with the Ontario Autism Program.
- Enrolled in Core Clinical Services means they accepted a core invite and have not exited the OAP, whether or not they have a funding agreement yet.
- Active Core Funding Agreement means a signed funding agreement is in force; it is a subset of enrolled.
- Receiving services is not counted in this FOI series at all.
Calculation
Waiting = registered − active funding agreements: 91,974 − 20,711 = 71,263 (77.5%).
Monthly growth: 918 registered per month minus 11 active funding agreements per month = 907 net new unfunded children per month. This is a historical Jan 7 → May 13, 2026 comparison, not a forecast.
Interpretation
This library exists because the headline figure, its definition, and the arithmetic behind it are easy to blend into one sentence. Kept apart, they let a reader check the math and see that "waiting" here means no active funding agreement, not no services at all.
Read the boundary before drawing a conclusion
- Administrative data
- WHO did not audit Ontario; Ontario's reported waits (5+ years for families registered in August 2021 (community-reported, Ontario Autism Coalition, July 2026)) can be compared with WHO's guidance.
- Limits of inference
- Aggregate records do not predict an individual child's outcome, rank every province, or establish a court finding.
- Clinical research
- The peer-reviewed intervention studies cited on this page (Dawson, Rogers, Cohen, Taylor, Lovaas, Reichow) describe research populations generally — they are not an audit of any individual Ontario provider or family, and no lifetime-cost or ROI figure is derived from them here.
- Source and review
- Keep each claim with its own population, time period, and source; the current OAP snapshot was last reviewed in August 2026.

Why early intervention timing is the relevant comparison
Published developmental research examines outcomes associated with earlier intervention for particular populations and study designs; it does not establish a universal age window, a guaranteed effect size, or an outcome for a specific child. WHO's guidance on timely, evidence-based psychosocial support is the standard Ontario's administrative wait is measured against here — not a province-by-province ranking or a lifetime-cost estimate.
WHO autism guidance and Ontario access →What the Charter and UNCRPD say about access
Section 15 of the Charter and the UNCRPD establish a right to non-discriminatory access to essential health services. Multi-year delays for a time-sensitive disability intervention raise serious questions under these standards — a legal analysis, not a court finding.

Frequently asked questions
Clarifying the data and research cited throughout this page.
Latest FOI data shows 91,974+ children registered with OAP as of May 2026 (MCCSS FOI via OAC · May 2026). This represents growth from 70,176 reported by the Financial Accountability Office (FAO) in their 2023–24 MCCSS Spending Plan Review (March 2024). Both figures are from government sources.
The World Health Organization describes timely access to evidence-based psychosocial interventions as important. WHO guidance does not create an Ontario queue estimate or a universal age cutoff for an individual child.
No. Population-level economic studies are not converted into an individual prediction or an Ontario waitlist dollar amount here. The relevant source, population, and limitations must be reviewed before any comparison is made.
As of May 13, 2026 (Ontario Autism Coalition FOI), 24,417 children are enrolled in Core Clinical Services and 20,711 have active Core Funding Agreements — not proof of service receipt — (22.5% of 91,974 registered). This means 71,263 children (77.5%) are waiting for a funding agreement. These figures do not include children still awaiting an autism diagnosis.
