We started noticing missed milestones around 14 months. He was just a playful little guy… we love him to death. The journey led to a diagnosis of non-verbal severe autism. He is more or less like every other little boy. But our biggest struggle is accessing publicly funded services that are supposedly available. We know exactly what we need. We know when we need it, but for whatever reason there's a wait list. The most critical window for a child is between the ages of 0 to 6. We know this. These are time-sensitive interventions that require immediate access. These therapies are recognized globally as improving the quality of life for every person with an autism diagnosis. This requires tireless advocacy to ensure autistic individuals receive the right care and integrated services. Follow the data. It is there for a reason.
The science demands action
71,263 children are waiting past the evidence-based intervention window, every month of delay has measurable consequences.

Yearly core clinical allocation range
FAO reports annual core clinical allocations ranging $6,600 to $65,000, with an average annual commitment around $34,000 (2023–24). Core services require waiting to be invited based on registration date.

Before joining the OAP waitlist, Ontario diagnostic waitlists average 12–24 months at public hospitals. This pre-waitlist delay means total time from first concern to therapy often exceeds 5–7 years, an invisible bottleneck in official statistics.

Key claims are paired with their source, evidence tier, and verification date so readers can inspect the public record directly.
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)
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
