How to Make the Shift to Adult Services Easier in Autism
Executive Summary
Key Findings: The transition at age 18 is often described as "falling off a cliff" because school-based supports under the Ontario Autism Program (OAP) typically end. Success for young adults in Mississauga depends on early transition planning - ideally starting between ages 14 and 16 - to secure adult-funded services. By bridging the gap between Monarch House’s clinical supports and provincial resources like Developmental Services Ontario (DSO) and the Ontario Disability Support Program (ODSP), families can build a sustainable "adult roadmap" that includes financial stability, inclusive employment, and independent housing.
- Clinical Continuity: Transitioning to adult-focused ABA, speech, and occupational therapy at Monarch House.
- Financial Scaffolding: Applying for ODSP to secure health benefits and income support upon turning 18.
- Adult Service Gateway: Registering with DSO (Developmental Services Ontario) to access adult programs.
- Employment & Education: Leveraging specialized programs like Project Search for workplace integration.
- Advocacy Networks: Connecting with Autism Ontario and the Autism Alliance of Canada for systemic support.
Why is the transition to "Adult Services" different in Ontario?
In Ontario, the support system shifts from the "Children's" branch to the "Adult" branch of the Ministry at age 18. This requires a completely new eligibility assessment through Developmental Services Ontario (DSO).
- The DSO Hurdle: The DSO is the single point of access for all adult ministry-funded supports. Families should start this process as soon as the child turns 16 to avoid long waitlists.
- Financial Shift: While children's benefits are often based on family income, ODSP is based on the individual's disability and financial status once they reach adulthood.
- Mental Health Context: Organizations like the CMHA become vital as young adults face the stress of leaving familiar school routines and entering the workforce or post-secondary life.

How does Monarch House support the "Aging Out" process?
Monarch House does not stop at age 18. We provide an "interdisciplinary bridge" to help teens transition into adulthood with confidence.
- Planning for the Future: Our psychotherapists help families manage the emotional transition of a child growing into an adult.
- Life Skills Maintenance: Continuing occupational therapy ensures that skills like cooking, laundry, and hygiene are not lost once the school routine ends.
- Integrated Care: We collaborate with the DSO and other local Mississauga health authorities to ensure our clinical goals align with the adult services the individual is receiving.

When exactly should we start the application for DSO and ODSP?
You should contact Developmental Services Ontario (DSO) when your child is 16 years old. You can apply for the Ontario Disability Support Program (ODSP) as early as six months before your child's 18th birthday.
Does my child need a new diagnostic assessment to get adult services?
Yes, the DSO requires a psychological assessment that confirms a developmental disability. It must be completed by a registered psychologist and meet specific criteria. Monarch House can assist in navigating these requirements.
What happens if my child wants to go to University or College?
Many Mississauga-area institutions (like Sheridan or UTM) have specialized "Accessibility Services" offices. We can help your teen develop self-advocacy skills so they can request the accommodations they need to succeed in higher education.
Are there "Day Programs" for adults who aren't ready for full-time work?
Yes. Through the DSO, you can access community-based day programs that focus on social interaction, community engagement, and life skills. Monarch House also provides private adult services tailored to fill these daily gaps.
