Yes, the waitlist has exploded by approximately **285%** since 2019, growing from 23,000 to over **88,175 children** by Jan 2026. [FOI] The number of new registrations outpaces service entry by a ratio of **3 to 1**. This exponential growth is driven by increased diagnosis rates and insufficient annual funding increases, creating a compounding backlog that pushes service access further out of reach for new registrants.
This growth reflects increased autism diagnoses, greater awareness among families, and chronic underfunding of the Ontario Autism Program. The Financial Accountability Office projects the waitlist could exceed 100,000 children by 2027 without significant policy changes. Current funding levels support services for only a fraction of registered children each year.
In 2019, the government promised to clear the autism backlog through program restructuring. Six years later, a family who registered in 2020 with a 3-year-old is still waiting as of 2026 with a 9-year-old. Their wait has outlasted multiple government announcements of increased funding, illustrating how incremental investments cannot keep pace with exponential waitlist growth.
