FAQ
As of March 4, 2026, 89,799 children are registered with the Ontario Autism Program and waiting for core clinical services. This grew from 70,176 in the 2023-24 baseline and represents a ~290% increase from ~23,000 at the time of the April 2019 OAP redesign. The waitlist has grown despite increased funding — a pattern the FAO's 2024 OAP analysis attributes to systemic capacity constraints rather than funding shortages alone. Approximately 23% of registered children have active funding, meaning 77% are still waiting (69,166 children).
The March 4, 2026 backlog data shows 89,799 children registered in the OAP and 69,166 still waiting for a funding agreement. That supports the conclusion that delays are substantial, but this page avoids assigning a single province-wide average wait in years or a fixed regional pattern unless a source directly publishes it.
Ontario's OAP spending reached $691.2M in 2023-24 (FAO), up from $628 million the prior year (2022–23) and approximately $409M in 2017 — roughly a 54% rise from 2017 to 2022–23. Over the same period, the service rate has fallen to 23% (current). The FAO observed in its 2024 OAP analysis that capacity constraints left portions of allocated funding unspent in 2022–23, indicating that provider availability, not budget volume alone, is a binding constraint on service delivery (source: FAO, MCCSS Spending Plan Review 2023–24, fao-on.org).
Only 23% of children registered with the OAP have active funding agreements as of March 2026 (FOI data). The service rate has fallen to 23% since the 2019 OAP redesign.
Official OAP data sources include: (1) Ministry of Children, Community and Social Services - publishes annual reports and waitlist updates at ontario.ca/OAP, (2) Financial Accountability Office - comprehensive analysis at fao-on.org, (3) Ontario Human Rights Commission - inquiry findings at ohrc.on.ca, (4) This Data Hub - curated datasets and visualizations. Data is updated quarterly for waitlists and annually for financial reports. Always verify data dates and sources.
Regional access conditions can differ across Ontario because provider availability, diagnostic access, travel burden, and service mix vary by community. This page does not present fixed regional percentages or wait bands unless they are directly sourced on the page.

Documented OAP registration counts show growth at key points: ~23,000 children (2019, at the time of the April 2019 OAP redesign), 70,176 (FAO-verified 2023–24 baseline), and 89,799 (FOI March 2026). The current figure is a ~290% increase over the 2019 baseline. Over the same period the share of registered children receiving active funding has fallen to 23%. The FAO's 2024 OAP analysis attributes the persistent gap between registration growth and funded enrolment to provider capacity constraints in the service delivery model (source: FAO, MCCSS Spending Plan Review 2023–24, fao-on.org).
