Since 2016, Alice Saddy Association, Ingersoll Support Services and Community Living St. Marys and Area have been working together to maximize their strengths and share their knowledge to more effectively support individuals in their communities. In 2019, South-East Grey Support Services and Quad County Support Services joined this group of like-minded organizations.
In May 2020, Southwest Collaborative Communities (SCC) was incorporated as a formal collaborative of these five developmental services agencies in Southwestern Ontario.
