| Metric | Count | % of Registered | Notes |
|---|---|---|---|
| Total Registered | 87,692 | 100% | All OAP registrations |
| Without Active Funding | 67,399 | 76.9% | Waiting for services |
| Enrolled in Core Clinical Services | 23,875 | 27.2% | In assessment or service pipeline |
| Active Funding Agreements | 20,293 | 23.1% | Receiving funded services |
| Average Wait Time | 5-7 years | — | Registration to core clinical services |
| Annual Funding Gap | $600M+ | — | FAO analysis (2024) |
The waitlist has grown continuously since the 2019 OAP reform. The 281% increase represents a compounding failure of funding to keep pace with registrations.

The Ontario government does not publish a regional breakdown of waitlist data. These are estimates based on regional population, known service capacity, and third-party research. A full FOI to MCCSS for regional data has been requested.
| Region | Estimated Children Waiting | Notes |
|---|---|---|
| Toronto (GTA) | 25,000-30,000 | Highest demand, longest waits |
| Ottawa | 8,000-10,000 | Second largest urban concentration |
| Hamilton / Niagara | 5,000-7,000 | Regional variation |
| London / SW Ontario | 7,000-9,000 | Regional SPO coverage |
| Northern Ontario | 3,000-5,000 | Geographic access barriers |
| Other / Rural | 15,000-20,000 | Dispersed across regions |
Even at the maximum OAP funding level of $65,000/year, families face a gap compared to the true cost of intensive ABA therapy ($60,000-$95,000/year). The FAO's $600M+ figure represents the aggregate additional investment needed to meaningfully serve all registered children.
Full FAO Report Analysis →The World Health Organization recommends that autism intervention begin within months of diagnosis, during the critical 0-6 developmental window. Ontario's average wait of 5-7 years means:
By WHO standards, Ontario's OAP waitlist represents a systemic failure to meet evidence-based care timelines for the overwhelming majority of registered children.
