School-Age vs Adult Services: Navigating Ontario's Autism "Services Cliff" at 18

Compare the supports available during school age (6-17) with what happens after 18 when children transition to the adult developmental services system. The "services cliff" is a major concern.

Quick summary

  • Side-by-side comparison of School-Age (6-17) vs Adult (18+) autism services
  • The transition from school-age to adult services is widely described as falling off a "services cliff." Daily structure disappears, OAP eligibility ends, and adult systems have their own long waitlists. Families must begin planning at age 14-16 by contacting DSO, applying for ODSP, and getting on Passport waitlists early.
