Analysis
The teen-to-adult transition is a major service gap in Ontario's autism system. Daily school structure disappears, OAP eligibility ends, and adult services have separate, lengthy waitlists. Families must start transition planning at age 14-16 to mitigate the impact of the "services cliff."
Frequently asked questions
At 18, autistic individuals lose: OAP eligibility, school-based daily structure, child and adolescent mental health services, and paediatric healthcare coordination. Adult replacements (ODSP, Passport, adult mental health) all require separate applications with their own waitlists.
Start at age 14-16: contact DSO, apply for ODSP pre-approval, get on Passport waitlists, apply for DTC and RDSP, explore supported employment programs, and include transition goals in the IEP. The earlier you start, the smoother the transition.
Yes, but limited. Ontario offers Employment Supports through MCCSS, Ready Willing and Able (national program), and some regional supported employment agencies. However, the unemployment rate for autistic adults remains over 80% in Ontario, reflecting significant gaps in available supports.
