Developmental Services Ontario (DSO): What Families Need to Know
Quick Summary
- DSO is the gateway to adult developmental services in Ontario, housing, community participation, and more
- OAP funding ends at age 18 with no automatic transition to adult services
- Families should start DSO planning at age 16-17 due to long waitlists for residential services
The benefits landscape
Financial support is available, but navigating it takes time families are already spending on the waitlist.

What DSO Provides Access To
Housing & Supported Living
Group homes, supportive living arrangements, and host family models. Housing is often the longest-lead item, waitlists can extend well beyond 10 years in some regions.
Funding & Benefits
Adult funding programs including the Passport Program (community participation), ODSP income support, and person-directed planning. Each has separate eligibility criteria.
Decision-Making Supports
Families may need clarity on power of attorney, guardianship, and capacity topics as youth approach 18. DSO can connect families with resources.
The Transition Problem
The transition from child to adult services in Ontario has been described as a "cliff" by families and advocates. When the Ontario Autism Program ends at age 18, there is no structured transition to adult supports. Families must independently navigate DSO application, ODSP eligibility, and Passport Program waitlists, often while simultaneously losing the OAP supports their child has relied on.
Many Never Received OAP Services
With 69,166 children waiting for OAP funding and average waits of 5+ years, many autistic youth will age out of the OAP at 18 without ever receiving core clinical services, then face additional waitlists in the adult system.

What is DSO (Developmental Services Ontario)?
Developmental Services Ontario (DSO) is a system of regional offices that serve as the access point for adult developmental services funded by the Ontario government. DSO determines eligibility for services, conducts application processes, and maintains waitlists for adult programs including residential supports, community participation, and person-directed planning.
When should families contact DSO?
Families should begin engaging with DSO well before a child turns 18. Planning for the transition from child to adult services can take years, especially for housing. Contact your regional DSO office when your child is 16-17 to understand the application process, required documentation, and current wait times.
What happens when OAP funding ends at age 18?
The Ontario Autism Program (OAP) ends at age 18. There is no automatic transition to adult services. Adults must separately apply to DSO for adult developmental services, to ODSP for income support, and to the Passport Program for community participation funding. Each program has its own eligibility criteria and waitlist.
How long are DSO waitlists?
DSO waitlists for residential services are among the longest in Ontario's social service system. Wait times for supportive housing can extend beyond 10 years in some regions. Community participation and day program waits are generally shorter but still significant. There is no published government timeline for service delivery.
What is the Passport Program?
The Passport Program provides funding for adults with developmental disabilities to participate in community activities, develop work skills, hire support workers, and access respite. Eligibility requires DSO application and confirmation of a developmental disability. Funding amounts vary and are subject to availability.
