Direct answer
If the current net growth rate holds, an estimated 73,990 children could be waiting without funded Ontario autism services about a year out, roughly early 2027. That starts from the 69,166 children waiting as of March 4, 2026 and adds an estimated net increase of about 402 unfunded children per month. Within about two years, roughly early 2028, the estimate rises to about 78,814. This is a projection, not a measured count.
These are straight-line projections. They take the 69,166 children waiting as of March 4, 2026 and add an estimated net increase of about 402 children per month. They assume the registration and enrollment rates stay constant. They are approximate scenarios, not measured counts or an official forecast.
The starting point is the 69,166 children who were registered in the Ontario Autism Program but waiting without funded services as of March 4, 2026, per Ontario Autism Coalition freedom-of-information data (CSS2026-0749). From there, the waitlist grows by the gap between two monthly rates.
About 850 children register for the program each month. Only about 448 start funded services in the same period. The difference, an estimated 402 children a month, is added to the group waiting. Over 12 months that is roughly 4,824 more children. Over 24 months it is roughly 9,648 more.
Because the funded share has stayed roughly flat per CBC FOI, and because CBC documented periods where the number of funded children fell, the net growth used here is a conservative estimate. CBC News documented periods where the number of funded children fell even as registrations grew (in one two-week period 151 fewer children were funded while 456 more registered), so the real net could be higher than this straight-line estimate.
This is a simple straight-line estimate. It assumes the monthly registration rate of about 850 and the estimated funded-enrollment rate of about 448 both stay the same through 2027. Real rates can change if the program funds more children, if registrations rise or fall, or if the budget shifts.
The projection also does not include children who are still awaiting an autism diagnosis and cannot yet register. The figures count only children already registered in the Ontario Autism Program. The true number of children needing services is larger than the registered count.
