Ontario guide for ages 14-18
Begin at age 14, add goals to the IEP, apply to Developmental Services Ontario at age 16, and prepare the adult-income application before the 18th birthday.

Start with the deadline that applies
Age 14: put transition goals in the IEP
Make education, employment, living, and community goals specific and timed.
Age 16: apply to DSO
DSO is the entry point for adult developmental-service applications.
Six months before 18: apply for ODSP
Starting early can reduce a gap in financial support at adulthood.
In brief
Apply for ODSP
Delays mean gap in financial support
Apply to DSO
DSO waitlists can be 2+ years
Guardianship decision
After 18, requires court application
Add transition goals
Required by law in Ontario schools
Follow this timeline to ensure your child is prepared for adult services at 18.
Transition planning covers every area of adult life, including 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.
Start formal transition planning at age 14 through the IEP process, to avoid the "services cliff" that occurs at 18 when OAP funding ends. Ontario schools are legally required to include transition planning in IEPs starting in Grade 9.
At age 18, multiple supports end simultaneously while adult services have separate applications and their own waitlists. What stops includes OAP Core Clinical Services funding (with no automatic transfer to an adult equivalent), school-based EA support at graduation or age 21, pediatric healthcare providers, parental legal authority (without POA or guardianship), and Child Disability Benefit payments.
Apply to DSO at age 16 due to waitlist delays. DSO is the gateway to adult developmental services including Passport Program funding, residential supports, community participation supports, caregiver respite, and person-directed planning.
Apply for ODSP 6 months before the 18th birthday. Delays in applying mean a gap in financial support once OAP funding ends at 18.
A transition IEP must include goals for post-secondary education or training, employment goals and work experience plans, independent living skills objectives, community participation goals, and a specific action plan with timelines. This is required by law in Ontario schools starting in Grade 9.
Take Action
Ontario families assembled this evidence from the government’s own records. Put it to work.
Has the autism waitlist grown or shrunk under the current government?
VerifiedWhen the current government took office, it promised to clear the autism backlog, yet a 2025 survey cited by Ontario Autism Coalition found the waitlist has nearly tripled, with an average wait of more than five years for services. [OAC] This trend directly contradicts commitments to faster, needs‑based access. Last verified: 2026-08-10

How do wait times affect family well-being?
VerifiedAccording to Ontario parent reports compiled in the 2025 Ontario Autism Coalition survey, prolonged wait times correlate with rising mental‑health crises: families described self‑harm, school refusal, and escalating behaviour after years without therapy. [OAC] Delays in support do not keep children stable; they actively increase risk and complexity of future care.

Did 2025 funding changes solve the waitlist?
VerifiedOntario announced increased autism funding and a Workforce Capacity Fund in 2025 to help providers hire staff and expand services. However, FAO and community survey data show that waitlists remain years long, suggesting that one‑time grants alone cannot fix a structurally under‑resourced system. [FAO] Sustainable, multi‑year funding is required.
