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

How long do families wait for Ontario autism services?
Ontario autism wait times for core clinical services now exceed 5+ years (2026). Most families currently receiving invitations registered in 2020 or earlier. This delay far exceeds the sensitive early intervention window recommended by developmental specialists.

Can autistic students get an educational assistant (EA)?
Schools may assign EAs based on IEP needs, but 47% of families report insufficient supports. EA availability varies by board and often fails to match clinical needs, leaving many autistic students without necessary classroom support.

How much does Ontario fund for autism treatment?
Core Clinical Services funding ranges $6,600-$65,000 per year based on age/needs (with a total OAP budget of $965M for 2026-27, up from $779M in 2025-26, per the Ontario Budget tabled March 26, 2026). This is direct funding—families choose public or private providers. However, intensive ABA therapy can cost up to $95,000 USD/year (2020 US cost estimate cited in FAO 2020 report; Canadian costs vary), leaving significant out-of-pocket gaps.

How has the OAP changed over time?
The OAP shifted from direct service (pre-2019) to a "childhood budget" check system (2019-2020), back to a "needs-based" program (2021-present). Each reset caused massive delays. The current system is needs-based but lacks the funding to serve the 69,166 waiting children (excludes children awaiting diagnosis, MCCSS FOI · Mar 2026).
