MCCSS Compliance

The Ministry of Children, Community and Social Services (MCCSS) conducts compliance inspections of all ministry-funded Developmental Services Ontario agencies under the Services and Supports to Promote the Social Inclusion of Persons with Developmental Disabilities Act, 2008 (SIPDDA). DSO SCS was found to be in compliance with Ontario Regulation 299/10 of SIPDDA (Quality Assurance Measures) and/or policy directives applicable to MCCSS-funded services and supports for adults with developmental disabilities.
