Quick Answer: Transition to Adulthood: A Guide for Autistic Youth and Families
Editorial teamWhen your autistic child turns 18, they "age out" of children's services. This guide explains the transition to adult services in Ontario.
Transition to Adulthood: A Guide for Autistic Youth and Families
The transition to adulthood is one of the most challenging times for autistic individuals and their families in Ontario. At age 18, everything changes.
The "Age Out" Cliff
What Happens at 18?
When your child turns 18, they:
- ❌ Lose OAP eligibility (children's program ends)
- ❌ Lose pediatric services
- ❌ Lose school-based supports (unless in secondary school)
- ✅ Can apply for adult developmental services (eligible only if a psychological assessment shows significant limits in both cognitive and adaptive functioning)
The Problem
Adult services in Ontario:
- Have their own waitlists
- Have different eligibility criteria
- Offer different types of support
Planning Timeline: When to Start
Recommended Timeline
| Age | Action |
|---|---|
| 14 or earlier | Begin transition planning |
| 16 | Apply to DSO (Developmental Services Ontario) |
| 16-17 | Explore adult service options |
| 17 | Apply for ODSP (Ontario Disability Support Program) |
| 18 | Transition to adult services |
Pro tip: Start early. Adult services can take time to start, and spots open only when resources become available.

Employment Supports
Ontario Disability Employment Network (ODEN)

- Use its member directory to find an employment service provider near you
Community Agencies
Many offer employment services:
- Job readiness training
- Resume building
- Interview practice
- Job matching
Legal Considerations
Capacity and Decision-Making
At 18, your child is legally an adult. Consider:
If capable:
- They make their own decisions
- You can only help with their permission
If not capable:
- Apply for guardianship (requires legal process)
- A power of attorney for property or personal care is only possible if they are mentally capable of making one (age 18+ for property, 16+ for personal care)
- For health care decisions, Ontario's Health Care Consent Act lets certain relatives, including parents, decide without going to court
Estate Planning
Consider:
- Henson Trust (protects ODSP eligibility)
- Will (a will cannot name a guardian for an adult child; in Ontario only a court can appoint a guardian of the person)
- Registered Disability Savings Plan (RDSP)
Advocacy During Transition
Key Strategies
- Start early - at least 2 years before 18th birthday
- Document everything - keep records of all conversations
- Build relationships with adult service providers
- Join advocacy groups - strength in numbers
- Share your story - policymakers need to hear these realities
Common Challenges
⚠️ "Services don't exist in my area"
- Document the gap
- Contact your MPP
- Connect with regional advocacy groups
⚠️ "Waitlists are too long"
- Get on multiple waitlists
- Advocate for increased funding
- Explore private options if possible
⚠️ "Eligibility criteria are unclear"
- Ask for written explanation
- Request formal assessment if needed
- Ask for a review if you are found ineligible (DSO allows 25 business days from the date of the ineligibility letter to request one)
