OAP Funding by Age Band

Ontario publishes Core Clinical Services amounts by four age bands, and within each band by the support level assigned in your Determination of Needs. Up to age 3, the amount is $10,900 for limited or moderate needs, or $65,000 for extensive needs. Ages 4 to 9 have four levels: $8,900 limited, $24,500 moderate, $36,800 moderate-plus, and $65,000 extensive.

Ages 10 to 14 are $7,600 limited, $18,800 moderate, and $41,400 extensive. Ages 15 to 17 are $6,600 limited, $18,300 moderate, and $31,900 extensive. Two things follow from this: amounts step down as a child gets older, and support level matters more than age - an extensive-needs 4-year-old is funded at $65,000 while a limited-needs 4-year-old is funded at $8,900.

At 18, OAP childhood funding ends outright. There is no OAP amount for adults; families apply to Developmental Services Ontario for adult supports instead.

The published amounts step down with age, which reflects the program prioritizing early intervention. Your child still needs an individual funding decision - ask AccessOAP or your provider which age band and support level were applied, and how that maps to the published amounts above.

The problem is access. Many families face a a multi-year wait reported by an Ontario Autism Coalition community cohort in July 2026; it is not an official province-wide average. A child registered early may miss key early-intervention years before a core clinical invitation arrives.

When a young person turns 18, OAP childhood funding ends. Families must then apply for adult developmental services through Developmental Services Ontario (DSO), including Passport funding.

The shift from OAP funding up to $6,600–$65,000/year to adult supports can be hard. Planning should begin before age 18, but families need clearer notice and a verified adult-service plan.
