What is Developmental Services Ontario (DSO)?

Developmental Services Ontario (DSO) is the access point for adult developmental services funded by the Ministry of Children, Community and Social Services (MCCSS) in Ontario. There are 9 DSO locations across the province.

When you turn 18, your children’s developmental services such as Special Services at Home, Assistance for Children with Severe Disabilities, and services through the Ontario Autism Program end. This means that you must apply through DSO to see if you are eligible to receive adult MCCSS funded supports available in your community.

When you connect with your area DSO they will help you:

• understand and complete the application process.
• determine the kind of services and supports you need.
• get access to MCCSS funded services and supports that you need when a spot is available.
• find information in your community.

When should I apply?

When you turn 16, contact your area DSO to see if you are eligible for services. By starting the application process early, you may be able to avoid service delays when you turn 18. DSO will help you determine the supports that are available in your area and that meet your needs when you turn 18.

Update your information

It is important to keep your local DSO up to date about any changes in your situation. For example, call us if you are planning to move or change your phone number. This helps us to make sure that we have your current contact information and to confirm that you wish to remain in the service registry.
