Direct answer
Developmental Services Ontario (DSO) is the provincial gateway to adult autism services. To be eligible: be an Ontario resident, have a DSM-5 diagnosis of Autism Spectrum Disorder or intellectual disability (dual diagnoses are common and eligible), and be 18+ (apply at 16 because the ADS assessment takes 6-12 months). DSO connects eligible adults to Passport funding, supported independent living, day programs, group homes, and supported employment.

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 be an Ontario resident; you must have a DSM-5 diagnosis of ASD or intellectual disability (dual diagnoses are common and eligible); you must be 18 or older (DSO recommends starting at age 16 so eligibility is confirmed by the 18th birthday); your support needs must require a developmental service, confirmed through the ADS tool.
Once you contact your regional DSO, they will schedule an ADS (Assessment for Developmental Services). This is not a new diagnostic assessment — it uses your existing DSM-5 diagnosis. The ADS is a structured interview and questionnaire covering: daily living skills (cooking, hygiene, transportation, managing medication); communication; community participation; behaviour and mental health; and health needs.
DSO strongly recommends beginning your application at age 16 — two years before the 18th birthday. The eligibility confirmation process involves an ADS assessment and can take 6-12 months. Starting at 16 means eligibility may be confirmed by 17, allowing the Passport-funding pipeline to begin as close to 18 as possible.

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.

ADS results determine whether you are eligible for DSO services, and the support-needs tier that informs Passport funding amounts and service priority.
DSO does not deliver services directly. It confirms eligibility and coordinates access to service agencies. Main service categories: Passport funding ($5,000-$50,000/year based on ADS assessment); Supported Independent Living (own apartment with funded support visits); Congregate living / group homes (24/7 support staff; wait times can reach 5-15+ years in many regions); Day programs and community participation; Supported employment via DSO or Employment Ontario.

After eligibility is confirmed, the wait for the first funded service is typically 1-3+ years and varies by region. In Northern Ontario, waits for residential support can reach 5-15 years.
