WHO emphasizes timely access to evidence-based psychosocial interventions. Ontario has 89,799 registered children with 69,166 (77%) waiting for Core Funding Agreements. Long delays conflict with WHO's core principle that early intervention during ages 0-6 is critical for development.

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 89,799 children registered, 20,633 active Core Funding Agreements, and 69,166 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.

"Based on WHO Fact Sheet (2023) and Ontario Autism Coalition FOI (March 2026), Ontario's OAC-derived multi-year wait (OAC FOI analysis) does not meet WHO's emphasis on timely access to early evidence-based psychosocial interventions. Ontario's documented backlog — 69,166 children waiting for a funding agreement — reflects a system under significant strain."
