Primary sources only
FOI responses, FAO reports, MCCSS publications, Hansard, and budget estimates. No secondary interpretations without primary source verification.
Citation protocol
Each figure shows its source and date.
Cross-verification
Waitlist figures are checked against the FAO where both report the same measure.
Update protocol
Data pages include "Last verified" dates. Stale data (>90 days) triggers automatic review.

The standard we set
- Registered
- 91,974 children are registered.
- Active funding
- 20,711 have active funding.
- What the figures establish
- A funding agreement with the program, currently held by 22.5% of registrants, records an administrative status only. Whether care followed the signature is a separate question, one this page cannot answer from these figures alone. Each figure links to a named source and date; verify any of them.

children are registered in the Ontario Autism Program
22.5%
Only 20,711 children have active funding agreements (22.5%), less than one in four
Early Start Denver Model (ESDM) delivered to children aged 18–30 months produced significant gains in IQ, adaptive behaviour, and autism severity — some children no longer met diagnostic criteria at follow-up
Cochrane systematic review finds evidence that early intensive behavioural intervention (EIBI) may produce positive effects on adaptive behaviour and communication for young children with ASD (low certainty of evidence)
Evidence supports autism screening and intervention commencing in the first 2 years of life — earlier identification directly enables earlier intervention during the highest neural plasticity window
