The 49 Percentage Point Decline

Ontario autism service access has fallen from 72% in 2018 to 22.5% in 2025, a 49 percentage point decline. Despite the number of children receiving services remaining relatively stable (~18,000 to 20,711), the waitlist has grown from 7,000 to 71,263 as registrations outpaced capacity growth by nearly 2:1.

Note: The 2018 and 2025 programs are structurally different (IBI/IAP vs. OAP Core Clinical). This comparison illustrates the trend but the programs are not directly comparable.

What the 22.5% Service Rate Means for Families

If Your Child is Diagnosed Today at Age 3

  • 75% chance:Face multi-year waits for services (well past early intervention window)
  • 25% chance:Receive services within reasonable timeframe
  • 100% certain:Much of the 0-6 early window will be missed if waiting

Family Options While Waiting

  • Option 1:Pay $40K-$80K/year for private therapy (Ontario Autism Coalition estimate, 2024-2025; most cannot afford)
  • Option 2:Reduce work hours to provide care (lost income)
  • Option 3:Go without services (developmental consequences)

How many children are on the Ontario autism waitlist?

Verified

Latest FOI data shows 91,974 children are registered in the Ontario Autism Program (May 2026), while only 22.5% have active funding agreements. [FOI] An active funding agreement does not mean a child is receiving services; it is an administrative status distinct from service delivery. The Ontario Autism Coalition reported in July 2026 that some families in its community had waited more than five years. That report is not a province-wide average. Last verified: 2026-08-10

Why is there such a long waitlist?

Verified

FAO spending‑plan reviews show that, even as 91,974 children are registered in the OAP (May 2026), only 22.5% have active funding agreements. [FOI] This structural underfunding creates a permanent backlog: each year, more children join the waitlist than transition into therapy.
