88,175 children are registered with the Ontario Autism Program (OAP). Of these, 20,666 children (27.2%) 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.
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.
