Who qualifies for Developmental Services Ontario, when to register, how long the wait is, and what services DSO can connect autistic adults to.
Direct answer
Developmental Services Ontario coordinates access to provincially funded adult developmental services. Eligibility depends on Ontario’s current developmental-disability definition and supporting documentation; autism alone does not establish eligibility. Ask the regional DSO when an application can begin and which records are required.
Contact your regional DSO office as early as recommended rather than waiting until adulthood arrives, so an eligibility review has time to finish before other supports change. Bring your existing psychological assessment; if you do not have one, ask your area DSO about options before paying for a new one. Prepare to answer questions about your daily life, goals, and support needs, because those answers shape your priority for services and your Passport funding amount. Ask the regional office directly what records it needs and how long its own review typically takes, since timing varies by region and by applicant. Understand that confirming eligibility is a separate step from receiving a funded service, and ask what happens next so you are not caught off guard by a further wait. Find your regional DSO office through the provincial directory rather than guessing which one covers your area.

| Eligibility detail | Details | Source |
|---|---|---|
| Eligibility | Developmental Services Ontario is a network of 9 regional organizations that act as the single provincial intake point for adult developmental services. To be eligible: you must live in Ontario; you must be 18 or older (DSO recommends starting at age 16 so eligibility is confirmed by the 18th birthday); and you must have a developmental disability, shown by a written psychological assessment that documents significant limitations in cognitive and adaptive functioning and the age of onset. An autism diagnosis alone does not establish eligibility. | Developmental Services Ontario |
| Regional intake | Each of the 9 regional DSO organizations covers a defined geography. Your local DSO office processes your application and connects you to regional service agencies. Find your regional DSO at dsontario.ca. | DSO provincial directory |
Once DSO confirms you are eligible, a DSO assessor will set up two meetings, each about three hours, to complete the application package. Bring at least two people who know you well. This is not a new diagnostic assessment. The package has two parts: the Application for Developmental Services and Supports (ADSS) and the Supports Intensity Scale - Adult (SIS-A). The SIS-A measures support needs in home living, community living, lifelong learning, employment, health and safety, social activities, protection and advocacy, and behavioural and medical needs.
Eligibility is confirmed before these meetings. The information you give is used to set your priority for services and, through a scoring process, the amount of Passport funding above the base amount.
DSO does not deliver services directly. It confirms eligibility and coordinates access to programs that may include Passport funding, supported living, residential services, community participation, and employment supports. Availability, allocations, and waits vary; DSO eligibility does not mean a service is immediately available.
Ask the regional DSO when an application can begin. Eligibility review timing varies, so families planning a transition should confirm the current process directly.
Eligibility confirmation is not the same as receiving a funded service. Availability and waits vary by program, region, and assessed need; DSO says it may take some time before you get services.
To be eligible for DSO you must: (1) live in Ontario; (2) be 18 or older; and (3) have a developmental disability, shown by a written psychological assessment that documents significant limitations in cognitive and adaptive functioning. An autism diagnosis alone does not establish eligibility. DSO recommends starting at 16.
Ask your regional DSO when the application can begin and which records are needed. Timing varies, and an early application does not guarantee eligibility or immediate service access.
DSO says it may take some time before you get services, and people at the highest risk are prioritized. Ask your regional DSO. DSO eligibility confirmation is not the same as receiving services.
DSO connects eligible adults to: Passport funding ($5,665 to $45,604/yr); Supported Independent Living; Group homes; Community participation supports, including employment opportunities. DSO is a network of 9 regional organizations.
After DSO confirms eligibility, a DSO assessor completes the application package with you: the Application for Developmental Services and Supports (ADSS) and the Supports Intensity Scale - Adult (SIS-A). It covers your goals, current services, caregiver needs, and the support you need in daily life. DSO uses it to set your priority for services, and Ontario uses it to score how much Passport funding you can receive above the base amount.

Where can I get autism support without OAP funding?
You can self-refer to Developmental Services Ontario (DSO), local preschool speech and language programs, Infant Hearing Program, and EarlyON Centers (free drop-in play/support). Google "Preschool Speech and Language [Your City]" to find programs that operate independently of OAP.

Does OAP funding continue after age 18?
No. OAP services and funding end strictly at age 18. Youth must transition to adult services (DSO, ODSP) which have separate extensive waitlists. Families are advised to begin the transition process at age 16 to mitigate service gaps.

How long are supportive housing waitlists?
Supportive housing waitlists in Ontario are 10-20+ years long. Thousands of adults with developmental disabilities wait indefinitely for funded group home spots. Many remain living with aging parents due to the complete lack of available housing stock.
