WHO emphasizes timely access to evidence-based psychosocial interventions. Ontario has 91,974 registered children with 71,263 (77.5%) waiting for Core Funding Agreements. Long delays conflict with WHO's core principle that early intervention during ages 0-6 is critical for development.
Every question on this page traces back to one of these three numbers.

WHO materials emphasize timely access to support after diagnosis. Ontario's strongest current public backlog figures show a large queue for funded services rather than a system providing timely access for all families.
With 91,974 children registered, 20,711 active Core Funding Agreements, and 71,263 children waiting for a funding agreement, Ontario families can face long delays before funded services begin.

Children waiting for a funding agreement
The World Health Organization (WHO) provides evidence-based guidelines for autism intervention. Key recommendations include:
Start as soon as possible after diagnosis, not years later
Interventions most effective during early developmental period
Use proven approaches like ABA, speech therapy, occupational therapy
Support families as partners in intervention, equip with skills

Methodology
Full methodology at /sources/methodology.
The early intervention window for autism refers to ages 2–5, when brain neuroplasticity is highest and intervention produces the strongest long-term outcomes. WHO guidelines recommend beginning intensive behavioural and developmental support as early as possible after diagnosis. Children who begin therapy during this window consistently show greater gains in communication and adaptive behaviour.

End The Wait Ontario. (2026). Ontario Autism Services vs WHO Guidelines. Retrieved February 3, 2026, from https://www.endthewaitontario.com/answers/ontario-autism-services-who-guidelinesPlain Language:
"Based on WHO Fact Sheet (2023) and Ontario Autism Coalition FOI (May 2026), Ontario's OAC-reported multi-year wait (MCCSS FOI via OAC analysis) does not meet WHO's emphasis on timely access to early evidence-based psychosocial interventions. Ontario's documented backlog — 71,263 children waiting for a funding agreement — reflects a system under significant strain."
Ontario children deserve the same standard of care as other developed nations.
Demand WHO-Standard CareIs occupational therapy available through OAP?
Occupational therapy (OT) addressing sensory processing, motor skills, and daily living activities can be funded through OAP when clinically indicated for autism. [OAP] Many families report OT waitlists of 6–18 months even after securing OAP funding, compounding delays in accessing comprehensive care.

Can autistic students get an educational assistant (EA)?
Schools may assign EAs based on IEP needs, but 47% of families report insufficient supports. EA availability varies by board and often fails to match clinical needs, leaving many autistic students without necessary classroom support.

WHO recommends accessible, community-based early interventions for children with autism. Timely evidence-based psychosocial interventions improve communication and social engagement
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)
