The Ontario autism waitlist stands at 91,974 children as of May 2026, the latest FOI data available. Key 2026 developments include continued FAO warnings, the Carroll v. Ontario HRTO case, Ontario Autism Coalition advocacy, and the 2026 budget record; the no-announcement wording above is explicitly historical and pre-budget.
Spencer Carroll interviewed on CBC Radio One (Ottawa Morning) about his son's wait for autism services. Fourth major media appearance in one week. Aired to Ottawa's political and public service audience the morning after the CBC News investigation.
CBC Toronto's Enterprise Unit obtained 18 months of bi-weekly OAP progress reports via FOI. Key findings: 91,974 registered, only 20,711 funded (22.5%), with a 21% registration surge since mid-2024 reported in CBC's January 2026 data. Features End The Wait Ontario founder Spencer Carroll.
The Trillium: Ontario Autism Coalition demands new budget funding go exclusively to core clinical services. Spencer Carroll calls for independent audit authority: "Calling this the largest investment in program history is giving yourself a participation trophy."
The 2026 Ontario Budget added roughly one hundred and eighty-six million dollars in new money for the Ontario Autism Program, bringing annual funding to $965M. However, the Ontario Autism Coalition warned last year's increase "didn't move the needle on the core wait list."
CBC's investigation of the same bi-weekly OAP progress-report series describes the January 7, 2026 column: 88,175 registered and 20,666 with active funding agreements. The current May 2026 OAC update is documented separately.
HRTO File 2025-62264-I continues. Proceedings are ongoing as of February 2026 and no ruling has been issued.
Before the March 26, 2026 budget, the Fall Economic Statement had not included a new OAP-specific announcement beyond the annual base increase. The budget outcome is recorded in the linked budget analysis.
The Jan 7–May 13, 2026 comparison in the OAC/CBC FOI series works out to about 918 new registrations per month and 11 additional active funding agreements per month — a derived net change of about 907 per month. The March 26 budget raised OAP funding to $965M for 2026–27; these rates are not a forecast.
The Ontario Autism Coalition has continued advocacy campaigns including MPP outreach, public demonstrations, and media engagement. OAC is supporting individual HRTO filings.
The Financial Accountability Office of Ontario (FAO) has repeatedly warned that OAP funding is structurally insufficient. Their 2020 analysis estimated an annual annual funding level of $1.35B at 2018-19 service levels. Compared with the 2026-27 allocation of $965M, that historical benchmark is $385M higher — not a current service-cost estimate — while the registered cohort has grown to 91,974 children since FAO modelled ~40,700.
A Jan 7–May 13, 2026 comparison of the OAC/CBC progress-report series shows about 918 new registrations per month versus about 11 additional active funding agreements per month. This is a derived historical rate, not a promise or forecast. The FAO's $1.35B estimate applies to 2018–19 service levels; the March 26 Ontario Budget is covered in our budget analysis.

Carroll v. Ontario (HRTO 2025-62264-I) is an active proceeding. No ruling has been issued. Specific pleadings are not summarized while the matter is before the tribunal.
Important distinction between legal proceedings and advocacy content
The HRTO Case: Carroll v. Ontario (HRTO 2025-62264-I) is a specific human rights complaint filed by Spencer Carroll. This case alleges that making disabled children wait years for medically necessary services during their critical developmental window (ages 0-6) may constitute discrimination under the Ontario Human Rights Code.
This Website: Contains general advocacy content about Ontario's autism services system, including analysis of government announcements compared to independent data from the Financial Accountability Office (FAO), media coverage, and academic research. The views expressed are those of a parent-led advocacy organization.
Key Distinction:
The HRTO case makes specific legal claims that must be proven in a legal proceeding. The general advocacy content on this website represents analysis and opinions based on publicly available data. Readers should not interpret the website's general advocacy positions as legal advice or as statements about the likely outcome of any legal proceeding.
For information about filing your own HRTO complaint, contact the Human Rights Legal Support Centre or consult with a lawyer specializing in human rights law.
The Government of Ontario has pointed to annual OAP budget increases as evidence of commitment to the program. However, as of the 2025 Fall Economic Statement, independent analysis, including the FAO, had consistently found these increases insufficient to reduce the waitlist.
As of March 25, 2026 (pre-budget), the government had not announced: a waitlist elimination plan, a target date for service delivery, additional emergency funding, or a response to the FAO's funding gap analysis (2020 estimate: $385M gap vs. 2026-27 budget at 2018-19 service levels). The 2019 comparison uses an approximate historical baseline and is not presented here as a precise current growth rate.The March 26, 2026 Ontario Budget may have addressed this, see our budget analysis for details.

How many children are on the Ontario autism waitlist in 2026?
VerifiedAs of May 13, 2026, 91,974 children are registered with the Ontario Autism Program. However, only 20,711 (22.5%) have an active Core Funding Agreement. This represents ~300% growth in registrations since 2019, with 71,263 children still waiting for essential funding.

Why is there a backlog in Ontario autism services?
VerifiedThe waitlist for core autism services has grown dramatically. FOI data showed 91,974 children registered (May 2026), representing a massive increase from previous years. Because invitations to core services are limited by fixed budgets, tens of thousands of children remain unserved, creating multi-year backlogs.

Has the government cleared the autism backlog?
VerifiedNo. Government claims of "clearing the backlog" refer only to administrative invitations, not actual service delivery. While 91,974 children are registered, 71,263 still lack funding for clinical therapy. May 2026 data confirms that only 22.5% of children have accessed core services.

How much does Ontario fund for autism treatment?
VerifiedCore 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.

Does Ontario publish transparent autism waitlist data?
VerifiedOntario does not publish transparent, real-time waitlist data for the Ontario Autism Program. Families do not know their position in the queue or when services will begin. The Financial Accountability Office provides periodic reports, but detailed enrollment timelines are not publicly available.

How has the OAP changed over time?
VerifiedThe 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 71,263 waiting children (excludes children awaiting diagnosis, MCCSS FOI via OAC · May 2026).
