End The Wait Ontario's canonical $385M annual <a href="/oap-funding-guide" class="text-blue-600 hover:underline font-medium">OAP funding</a> gap comes from the Financial Accountability Office's 2020 estimate that $1.35 billion per year was needed to deliver autism services at 2018-19 levels for 40,700 children — minus the $965M budgeted for 2026-27. Other estimates use different baselines: actual current need (89,799 children) yields a higher figure; comparing to historical underfunding yields lower; comparing to intensive-ABA cost models yields much higher. All point to systemic underfunding.
Start with the short answer, then reveal deeper context where helpful.
The Financial Accountability Office of Ontario's 2020 review of MCCSS spending estimated that $1.35 billion per year was needed to deliver Ontario Autism Program services AT 2018-19 SERVICE LEVELS for the 40,700 children registered at that time. The 2026-27 Ontario Budget allocated $965 million to the OAP. The arithmetic: $1.35B − $965M = $385M annual shortfall.
Several other annual-gap estimates appear in public discussion. (1) "$570M shortfall" — FAO's prior estimate against the smaller 2024-25 $779M budget. (2) "$600M shortfall" — used by some advocacy groups, rounding the FAO estimate. (3) "$1.9B-$2.5B" — End The Wait Ontario's own estimate of what would be needed to fund all currently-registered children at typical needs-based amounts ($22K average × 89,799 ≈ $1.98B, minus current spending). (4) "$3.78B" — estimates assuming intensive ABA at $65,000/child × 89,799 minus the $965M budget.
When writing to MPPs, journalists, or policymakers, the $385M figure is the most legally defensible because it cites the FAO and uses the most conservative service-level benchmark. It is the gap that cannot be argued away.

The 2026-27 Ontario Budget allocated $965 million to the OAP. The arithmetic: $1.35B − $965M = $385M annual shortfall.
This is the most conservative defensible gap figure because it uses (a) an independent, government-funded oversight body's estimate (FAO), and (b) the lowest-intensity service-level benchmark (2018-19, before the 2019 redesign expanded eligibility). End The Wait Ontario uses this figure as our canonical because it is the hardest to dispute.

All of these point to the same underlying reality: persistent and severe underfunding relative to need. The differences come from which baseline you choose: 2018-19 service levels (FAO's most defensible benchmark), today's registration count (89,799), or evidence-based intensive intervention costs ($40K-$80K per child per year per WHO and clinical research).
When writing to MPPs, journalists, or policymakers, the $385M figure is the most legally defensible because it cites the FAO and uses the most conservative service-level benchmark. It is the gap that cannot be argued away.
However, families and advocates can legitimately point out that even fully closing the $385M FAO gap would only restore 2018-19 service levels to today's much larger registered population — a structural mismatch that requires either (a) more funding, (b) more provider capacity, or (c) lower per-child intensity. The honest framing: "$385M is the floor, not the ceiling."
