The Ontario autism waitlist has 89,799 children registered as of March 2026. Of these, 69,166 children (77%) are still waiting for OAP core funding; a 2025 Ontario Autism Coalition family survey estimates average waits of 5+ years (no official government average wait is published). Only 23% of registered children have received core services.
The Ontario Autism Program (OAP) uses an age-based registration queue. gov Unlike healthcare triage, children are not prioritized by need. With over 89,799+ children registered foi and limited annual funding slots, the backlog creates multi-year delays that exceed the critical neurodevelopmental window (ages 0-6).
Real Families, Real Wait Times

The Ontario Autism Program (OAP) waitlist tracks every child registered for provincial autism funding. As of March 2026 (FOI data), 89,799 children are registered, and only 23% have an active funding agreement. The remaining 69,166 children are actively waiting, with no confirmed start date. foi
OAP wait times in 2026 average 5+ years provincially. fao Autism services wait times in Ontario have worsened every year since 2019, when the program moved to the current age-based registration model. gov At the current net growth rate of 850 children per month (FOI data), the waiting list is projected to reach approximately 78,814 by December 2027 without significant policy reform. foi
How long is the Ontario autism waitlist? Families who register today can expect to wait 5+ years before receiving an invitation to core clinical services, longer than the entire critical neurodevelopmental window of ages 0–6.
Verified answers to the most common questions parents ask about the OAP waitlist.
The Ontario Autism Program waitlist has 89,799 children as of March 2026 (FOI). Average wait times exceed 5 years provincially. Families in Northern Ontario report even longer waits. Only 23% of registered children have active funding.
89,799 children are registered as of March 2026 (latest FOI data). Of these, 69,166 have no active funding agreement. 20,633 are enrolled in the core clinical pipeline. 20,633 have a funded agreement in place.
Demand exceeds funding by approximately $385M annually (FAO 2020 baseline at 2018-19 service levels vs the 2026-27 budget; the actual gap is larger at current demand). The program grew from ~23,000 registrations in 2019 to 89,799 by March 2026 (FOI data). Age-based registration, not needs-based triage, means urgency is never considered. New diagnosis rates outpace program capacity every year.
Access school-based IEP supports, apply for the Disability Tax Credit (DTC), explore community sliding-scale providers, and use any available OAP Interim Funding. Read our full guide on getting autism help while waiting.
There is no formal position appeal, placement is strictly by registration date. Families can file HRTO complaints, contact their MPP, or escalate through the Ontario Autism Coalition. See our OAP appeal process guide for all options.
Ontario has among the longest autism wait times in Canada. British Columbia and Alberta have substantially smaller per-capita waitlists. Ontario spends less per registered child than most comparable provinces despite having the largest autism program by enrollment.

“My son was diagnosed with severe, non-verbal autism at 14 months old. Like thousands of other parents, I was told early intervention was critical. And like thousands of others, I was placed on a waitlist that effectively has no end.”
, Spencer Carroll, Founder, End The Wait Ontario
Four years of phone calls. Two MP interventions. An ombudsman complaint. Emails to the Premier, the Minister, AccessOAP. Silence. Form letters. Nothing.
We\'ve paid thousands out of pocket for speech therapy, OT, whatever we could afford. The intensive behavioral support he actually needs costs more per month than most families spend on rent. We\'re not wealthy. We\'ve been drowning.
Then a clip of me discussing autism diagnosis and early intervention was shared on the World Health Organization\'s official social channels. A Canadian father talking about what timely support means, and what happens when children wait years for services that guidelines say should begin within weeks of diagnosis.
I built this organization because it should have existed when we needed it. I filed a human rights complaint because silence wasn\'t working. Carroll v. Ontario argues what thousands of families already know: making disabled children wait years for medically necessary services during their critical developmental window may constitute discrimination under Ontario\'s Human Rights Code.

HRTO Case Disclaimer
The legal claims in Carroll v. Ontario (HRTO 2025-62264-I) involve specific individual circumstances and are distinct from the general advocacy positions expressed on this website. This case alleges that wait times during documented critical developmental windows may constitute discrimination under Ontario's Human Rights Code.

The Data Story
Scroll through the data to understand the full scope of the problem.
2019, Where It Started
The Ontario Autism Program was redesigned in 2019. Families registered in hope. The program promised a pathway to services for their children.
2019–2026, ~290% Growth
Registrations grew at ~850 new children per month. But the funding and service capacity didn't keep pace. The gap between demand and supply widened every year.
The Funding Reality
$965M divided by 89,799 children equals roughly $10,746 per child per year. Adequate ABA therapy costs $40,000–$80,000 annually, a gap families report as financially unmanageable.
The Geography of Inequality
Northern Ontario families can be more than 300km from the nearest qualified provider. Even with OAP funding, there's nobody to deliver the services. Rural families face a double crisis.
Where This Is Headed
At the current rate of 850 new registrations per month (Ontario Autism Coalition FOI), total OAP registrations are projected to exceed 100,000 within approximately 14 months. Current funding trajectories cannot keep pace with this growth.
