Northwestern Ontario has the worst provider-to-child ratio in the province at 1:733—only 3 providers for 2,200 waiting children across 400,000 km². Families routinely drive 500+ km one-way for therapy sessions.
Urban centers like Toronto show better ratios (1:226) but still face4+ year waits. Rural regions have 3x worse ratios on average, with wait times exceeding 7 years in northern communities.
4 regions qualify as autism deserts (ratio > 1:400): Central East (Peterborough, Lindsay, Northumberland), Central West (Bruce, Grey, Dufferin, Wellington), Northern East (Sudbury, North Bay, Timmins), Northern West (Thunder Bay, Kenora). These areas face the most acute service shortages and longest wait times in Ontario.
Ontario has approximately 250 approved OAP providers for87,692 waiting children — a ratio that makes timely access to evidence-based early intervention effectively impossible for most families.

The data shows a clear crisis. Here's how to take action.
“My son was diagnosed with severe, non-verbal autism at 14 months old. Like thousands of other parents, I was told early intervention was critical. And like thousands of others, I was placed on a waitlist that effectively has no end.”
— Spencer Carroll, Founder, End The Wait Ontario
Four years of phone calls. Two MP interventions. An ombudsman complaint. Emails to the Premier, the Minister, AccessOAP. Silence. Form letters. Nothing.
We've paid thousands out of pocket for speech therapy, OT, whatever we could afford. The intensive behavioral support he actually needs costs more per month than most families spend on rent. We're not wealthy. We've been drowning.
Then a clip of me discussing autism diagnosis and early intervention was shared on the World Health Organization's official social channels. A Canadian father talking about what timely support means — and what happens when children wait years for services that guidelines say should begin within weeks of diagnosis.
I built this organization because it should have existed when we needed it. I filed a human rights complaint because silence wasn't working. Carroll v. Ontario argues what thousands of families already know: making disabled children wait years for medically necessary services during their critical developmental window may constitute discrimination under Ontario's Human Rights Code.
