The growth figure is approximately ~300%. Source: FAO context and Ontario Autism Coalition historical tracking for the baseline; latest count from MCCSS Ontario Autism Program figures, May 13, 2026, obtained by the Ontario Autism Coalition under Freedom of Information. Verified 2026-08-10.

The 2019 baseline of about 23,000 is approximate. The government did not publish exact real-time registration counts at the time of the April 2019 redesign. Because the baseline is approximate, the growth figure is rounded and shown with a qualifier.

The trend in detail

Around the April 2019 Ontario Autism Program redesign, an estimated 23,000 children were registered. By 2023-24, the Financial Accountability Office (FAO) reported 70,176 registered children, with 19,966 enrolled in Core Clinical Services (14,290 had received a payment). As of May 13, 2026, the MCCSS Ontario Autism Program figures, May 13, 2026, obtained by the Ontario Autism Coalition under Freedom of Information column shows 91,974 registered.

That is an overall increase of about ~300% in registrations since 2019. Between the last FAO report and the latest FOI column alone, registrations rose by 21,798 children, about 31%. CBC News reported registrations jumped about 21% since mid-2024.

Funded enrollment has not kept pace. As of May 13, 2026, only 20,711 of 91,974 registered children (22.5%) had active funding agreements. That leaves 71,263 children waiting without an active Core Funding Agreement.

Why the 2019 figure is approximate

2019 baseline
The 2019 baseline of about 23,000 children is not an exact government count. The province did not publish exact real-time registration figures at the time of the redesign. The estimate comes from Financial Accountability Office context and Ontario Autism Coalition historical tracking. Because the starting number is approximate, we round the growth figure and label it with a qualifier rather than stating it to the decimal.
Who is counted
These figures count only children registered in the Ontario Autism Program. They do not include children who are still awaiting an autism diagnosis and cannot yet register. The true number of children needing services is larger than the registered count.
