89,799
children are registered in the Ontario Autism Program
Only 23% of registered children have active Core Funding Agreements. This is down from 72% in 2018. The remaining 77% (69,166 children) face multi-year waits without funded services during the critical 0-6 intervention window when outcomes are best.

As of March 4, 2026 (Ontario Autism Coalition FOI), 20,633 of 89,799 children (23.0%) are enrolled in Core Clinical Services and 20,633 (23%) have active Core Funding Agreements.
The remaining 77% (69,166 children) wait an estimated several years for services, missing the critical 0-6 developmental window when early intervention is most effective.
| Year | Registered | Active Funding | % Funded |
|---|---|---|---|
| 2018 | ~25,000 | ~18,000 | 72% |
| 2022 | ~50,000 | ~15,000 | 30% |
| 2024 | 70,176 | ~17,500 | 25% |
| 2025 | 89,799 | 20,633 | 23% |
Ontario autism service access has fallen from 72% in 2018 to 23% in 2025, a 49 percentage point decline. Despite the number of children receiving services remaining relatively stable (~18,000 to 20,633), the waitlist has grown from 7,000 to 69,166 as registrations outpaced capacity growth by nearly 2:1.
Note: The 2018 and 2025 programs are structurally different (IBI/IAP vs. OAP Core Clinical). This comparison illustrates the trend but the programs are not directly comparable.

Current waitlist numbers, registration statistics
Ontario lags behind most provinces on autism service access. British Columbia eliminated its autism waitlist in 2021. Alberta's FSCD program has no age cap and no formal waitlist. Quebec provides direct funding without a multi-year queue. Ontario's 5+ year wait and 77.0% unfunded rate are the worst of any major province for families seeking timely services.
