About us

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 agencies located across the province; serving different counties and regions.

If you have a developmental disability, live in Ontario, and are 18 years old you must apply through DSO to see if you are eligible to receive adult ministry-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.

Talk to your area DSO to find out what services and supports are available and are right for you.
