WHO emphasizes timely access to evidence-based psychosocial interventions. Ontario has 88,175 registered children with 67,509 (76.6%) 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 88,175 children registered, 20,666 active Core Funding Agreements, and 67,509 children waiting for a funding agreement, Ontario families can face long delays before funded services begin.
WHO materials emphasize timely access after diagnosis
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

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 FAO/FOI data (CBC FOI Jan 2026), Ontario autism wait times of 5+ years do not meet WHO emphasis on timely access to early evidence-based psychosocial interventions. Ontario has among the longest wait times in the developed world."
Ontario children deserve the same standard of care as other developed nations.
