Step-by-step guidance
When an autistic child turns 18, they age out of children's services and enter a completely different system. This transition is often called the "services cliff" because many supports end abruptly while adult services have long waitlists and complex eligibility requirements.
Start planning at age 14, not 18. Here is the recommended timeline.
Monthly income support for eligible adults with disabilities
The Ontario Disability Support Program (ODSP) provides monthly income support to eligible Ontario residents with disabilities. It also provides employment supports to help people find and keep jobs.
As of 2024: Single person receives approximately $1,408/month (basic needs + shelter). Rates increase annually with inflation.
Get the ODSP application form from your local Ontario Works office or online. Complete the personal information sections.
A licensed healthcare professional (doctor, psychologist, psychiatrist) must complete the Disability Determination section.
Include proof of identity, immigration status, residence, and assets. Submit in person at your local Ontario Works or ODSP office.
You will be contacted for an in-person interview to review your application and verify information.
Processing typically takes 30-90 days. You will receive written notice of the decision. If denied, you can appeal.

Understanding housing waitlists and alternatives for autistic adults
In most of Ontario, the waitlist for supported housing for adults with developmental disabilities is 10 to 20 years. This is why early registration with DSO (at age 16) is essential.
Even with DSO eligibility confirmed years in advance, most families will need to plan for the adult child to live at home well into their 20s or longer.
Housing with 24/7 support staff, typically group homes. Through DSO.
Apartment or condo with periodic support visits.
Most common arrangement due to housing shortage.
Shared housing with others (with or without disabilities).
Moving from pediatric to adult healthcare providers
In Ontario, pediatric care typically ends between ages 17-19. Finding adult healthcare providers who understand autism can be difficult. Many adult providers have long waitlists or limited experience with autistic adults.
Start Early:
Begin planning the healthcare transition at age 16-17. Ask your pediatrician for adult provider referrals well before the transition date.
Medical Care:
Mental Health:
At age 18, individuals are presumed capable of making their own healthcare decisions. However, some autistic adults may need support with healthcare decision-making.
Options:
Powers of attorney, guardianship, and decision-making after 18
Every Ontario adult should have powers of attorney, but this is especially important for autistic adults who may need support with complex decisions.
Power of Attorney for Property
Authorizes someone to handle financial decisions, banking, and property. Can be effective immediately or upon incapacity.
Power of Attorney for Personal Care
Authorizes someone to make healthcare, housing, and personal care decisions if the individual becomes incapable.
If an adult cannot make decisions independently and powers of attorney are not an option, guardianship may be necessary. This is a serious legal step.
Guardianship Process:
Important: Guardianship should be a last resort. Consider less restrictive options like powers of attorney or supported decision-making first.
