88,175 children are registered with OAP as of January 7, 2026 (CBC News FOI). Only 23.4% have active Core Funding Agreements. 67,509 children (76.6%) are waiting without funded services. The waitlist has tripled since 2018 while the service rate fell from 72% to 23.4%.
The scale of the crisis
More than 3 in 4 registered children have no funded autism services in Ontario.

88,175 children are registered with the Ontario Autism Program (OAP). Of these, 20,666 children ($23.4%) are enrolled in Core Clinical Services and 20,666 (23.4%) have active Core Funding Agreements, leaving 67,509 children (76.6%) waiting an estimated several years for evidence-based therapy during the critical 0–6 developmental window when early intervention is most effective. See the FOI-verified waitlist data.
This means that more than 3 in 4 registered children are waiting without services during the years when autism therapy has the greatest impact.
The Ontario autism waitlist matters because early intervention during the critical 0–6 developmental window is most effective for autistic children.
WHO Guidance: The World Health Organization emphasizes timely access to early evidence-based psychosocial interventions. Clinical research supports beginning therapy as soon as possible after diagnosis. Ontario's multi-year wait times are among the longest in the developed world. Review the research citations and FAO evidence.

Current wait times, factors affecting wait duration, regional variations
Children cannot get autism therapy in Ontario because OAP funding covers only 23.4% of registered children. The OAP budget ($965M) is $385M below the FAO's estimated need. New registrations outpace funded spots by 402/month. Without private funds ($60,000–$80,000/year for ABA), most families must wait years for publicly-funded services.
Systemic constraints, funding gaps, policy barriers
Lost income, caregiver burden, long-term costs
Ontario provides up to $28,000/year per child (under 6) in OAP Core Clinical funding. British Columbia provides needs-based funding with no formal waitlist. Alberta's FSCD has no age cap and no queue. Manitoba and Saskatchewan also have shorter waits. Ontario's 76.6% unfunded rate is the worst of any major province for publicly-funded autism services.
