87,692 children are registered with the Ontario Autism Program (OAP). Of these, only 20,293 children (23.1%) receive core clinical services, leaving 64,400+ children (76.9%) waiting an estimated 5–7 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 Guidelines: The World Health Organization recommends that autism intervention begin as soon as possible after diagnosis, ideally within months, not years. Ontario's 5–7 year wait times are among the longest in the developed world.
