This is not an abstract policy discussion. This is what happens to real children and real families when they wait half a decade for services that should have started within the early developmental window, clinical research supports starting as soon as possible after diagnosis.

Your child receives an autism diagnosis. The paediatrician tells you early intervention is critical. You register with AccessOAP the same week. You feel hopeful, the system exists, and your child is in it. You start researching therapies. You learn about ABA, speech therapy, occupational therapy. You call AccessOAP and they confirm: your child is on the waitlist.
“We were told early intervention is critical. Then we were told to wait.”

You scramble for private options. A BCBA assessment costs $2,000-$3,000. You find out intensive ABA is $60,000-$95,000 per year. Your insurance covers a fraction, if anything. You start Foundational Family Services, free workshops that teach you strategies but are not the intensive, individualized support your child needs.
You have been paying for private therapy for a year. The credit cards are maxed. One parent has reduced their hours at work. You have spent $30,000 out of pocket, more than some families earn in a year. Your insurance company denied the latest claim because they say ABA is not medically necessary.
“I spend more on gas taking my child to therapy than we get in funding.”

Your child enters the school system without the intensive supports they needed two years ago. The IEP meeting is an exercise in managed expectations. The school has limited EA support, and your child is not the only one who needs it. Behavioural incidents are escalating. You receive calls from the school weekly, sometimes daily.
Schools have limited resources. Your child's IEP may not reflect the intensity of support they need. Parents often feel they are negotiating for bare minimums.
Educational Assistants are shared across multiple students. Your child may get 30 minutes of direct EA time per day in a system that should be providing hours.
Without therapeutic support, children enter school without the self-regulation skills they need. Meltdowns increase. Suspensions happen. Parents are called to pick up their child.
Birthday party invitations stop coming. Playground time becomes a source of anxiety. Your child knows they are different, but nobody has helped them navigate that.
The World Health Organization says early intervention before age 6 changes everything. Your child diagnosed at 2 is now 6. The critical window, the period of maximum brain plasticity when intervention produces the largest gains, is closing. The science is unambiguous on this point.
Skills that could have been built during the sensitive developmental period are now significantly harder to develop. The intervention your child will eventually receive will need to be more intensive, more expensive, and will produce less dramatic gains than it would have at age 2 or 3.
Five years. Your child is now 7, or 8, or 9. The critical window has passed. You have spent tens of thousands out of pocket. Your marriage has been tested. Your other children have asked why their sibling gets all the attention. And you are still waiting for services the government promised.
“Five years ago our son was diagnosed... all I feel is anger and heartache. Five years of preventable escalation, crisis, and trauma.”

As of March 4, 2026, 89,799 children are registered with the Ontario Autism Program. However, only 20,633 (23%) have an active Core Funding Agreement. This represents approximately 290% growth in registrations since 2019, with 69,166 children still waiting for essential funding.

Is the Ontario Autism Program underfunded?
Yes. The Financial Accountability Office (FAO) determined that $1.35 billion annually is needed to serve all registered children at 2018-19 service levels. The 2026-27 Ontario Budget allocated $965 million, leaving an estimated $385M+ annual shortfall. This gap is the primary driver of the perpetual 89,799+ child waitlist.
