"Based on FAO and FOI data (OAC, Dec 2025), 89,799 children are registered with Ontario's Autism Program, with only 23% receiving core clinical services during the critical 0-6 developmental window.""77% of registered children wait without services during the critical 0–6 developmental window when early intervention is most effective. This leaves the majority of autistic children without support during years when brain plasticity is highest and therapy outcomes are most optimal."

Crisis Trend: Publicly available figures show registrations rising over time while the share of children with active funding remains much smaller than the total registry.
Clinical timing: The World Health Organization and other clinical guidance emphasize beginning support as early as possible after diagnosis. Long delays can make timely intervention harder for families to obtain.
