Originally known as the Member Agencies Representative Council (MARC), The Toronto Developmental Services Alliance (TDSA) is a network of 27, not-for-profit organisations and agencies that provide a wide range of residential and specialized community-based programs and supports for individuals with developmental disabilities. Collectively, we serve thousands of individuals and families living in the city of Toronto and employ approximately 4,000 – 5,000 people.
What we do
The TDSA represents the interests of its member organisations in order to advocate on behalf of the populations we collectively serve;
How we do it
TDSA members collectively share information and their limited resources to address common issues, develop, and share innovative best practices, and respond to the emerging needs and interests of people with developmental disabilities and their families.
