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.
