The "Services Cliff" at 18
At age 18, multiple supports end simultaneously while adult services have separate applications and their own waitlists. This gap is the single biggest risk for autistic youth in Ontario.
What STOPS at 18
- OAP Core Clinical Services funding ends, no automatic transfer to adult equivalent
- School-based EA support ends at graduation or age 21
- Pediatric healthcare providers stop seeing patients (must find adult doctors)
- Parental legal authority ends, parents cannot make decisions without POA or guardianship
- Child Disability Benefit (CDB) payments stop
What CAN Start at 18
- ODSP, apply 6 months before 18th birthday for income and employment supports
- Passport Program, community participation, person-directed planning, respite
- DSO services, residential, employment, community supports (apply at 16 due to waitlists)
- RDSP, Registered Disability Savings Plan with government matching grants
- Employment Ontario, disability-specific job placement and coaching programs
Warning: Most of these have their own waitlists. Passport and DSO residential waitlists can be years long. Apply early.
