The transition from pediatric to adult services is one of the most important developmental windows for autistic youth. Start planning at age 14 to avoid the "services cliff" that occurs at 18 when OAP funding ends.
The crisis that makes planning urgent
The "services cliff" at 18 is steeper for children who spent their early years on this waitlist. Planning starts now — the funding ends at 18 regardless of what was received.

Follow this timeline to ensure your child is prepared for adult services at 18.
Comprehensive transition planning addresses all areas of adult life, not just services and funding.
Post-secondary options, vocational training, life skills programs
Work experience, supported employment, career planning
Housing options, daily living skills, community supports
Adult healthcare providers, mental health, self-care
Community connections, friendships, leisure activities
Guardianship, banking, benefits, legal capacity
Ontario schools are legally required to include transition planning in IEPs starting in Grade 9.
DSO is the gateway to adult developmental services. Apply at age 16 due to waitlist delays.
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.
Warning: Most of these have their own waitlists. Passport and DSO residential waitlists can be years long. Apply early.
