The Ontario Autism Program ends when a child turns 18 years old. There is no automatic transfer to adult services — families must actively plan the transition to programs such as the Ontario Disability Support Program (ODSP), Passport funding, and community living supports. Transition planning should begin no later than age 14 to avoid gaps in service.
Start with the short answer, then reveal deeper context where helpful.
The Ontario Autism Program is explicitly a children's program — eligibility ends on an individual's 18th birthday. Core clinical childhood budgets, Foundational services, and all OAP-funded supports cease at this threshold. There is no automatic handoff to equivalent adult autism services.
Key adult programs for autistic Ontarians after OAP include: the Ontario Disability Support Program (ODSP), which provides income and disability-related benefit support; the Passport Program, which funds community participation, caregiver respite, and support worker hours; Community Living Ontario services for individuals with significant support needs; and developmental services funded through MCCSS.

The transition from children's to adult services in Ontario is widely documented as a "cliff" — a sudden loss of structured support that can be destabilizing for autistic individuals and their families. The absence of a coordinated handover system means that families who do not plan in advance often face months or years without adult services after OAP ends.

Applications for ODSP and Passport should be submitted well before the 18th birthday, as processing times can be 6–12 months. School-to-adult-life transition planning under the Education Act (IEP transition component) should begin by age 14. The OAP regional office can provide referrals to adult service navigators.
