A clinical assessment process, usually led by a psychologist or physician, that determines whether a child meets the criteria for an autism diagnosis. A diagnosis report is typically required before OAP core funding can be used.

“
The cost of the years-long waitlist in London isn't only financial. It is measured in delayed access to therapy during developmental windows that clinical research identifies as time-sensitive.

Questions worth asking before you register

  • Is this service currently accepting new OAP-funded clients, or is there a separate waitlist for funded spots?
  • What is your current estimated wait, and can you confirm it in writing or by email?
  • Do you require a diagnosis report, physician referral, or specific intake paperwork before I can book?
  • Is there a deposit, hold fee, or cancellation policy attached to the waitlist?
  • If I also register with another provider, will accepting an opening here affect my other waitlist positions?

While you’re on a waitlist

Families don’t have to wait idle for a spot to open. A separate directory tracks free and low-cost services available across Ontario now.

How many children are on the Ontario autism waitlist in 2026?

Verified

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?

Verified

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.
