Service Percentage Has Declined Dramatically Since 2018
| Year | Registered | Active Funding | % Funded |
|---|---|---|---|
| 2018 | ~25,000 | ~18,000 | 72% |
| 2022 | ~50,000 | ~15,000 | 30% |

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:Critical 0-6 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 does Ontario compare to other provinces?
Ontario lags behind most provinces on autism service access. British Columbia eliminated its autism waitlist in 2021. Alberta's FSCD program has no age cap and no formal waitlist. Quebec provides direct funding without a multi-year queue. Ontario's 5+ year wait and 77.5% unfunded rate are the worst of any major province for families seeking timely services.
