Developmental Services Ontario

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 nine 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
