The Ontario Municipal Social Services Association (OMSSA) is a non-profit association whose members are Ontario's Consolidated Municipal Service Managers (CMSMs) and District Social Services Administration Boards (DSSABs).
Social services management was downloaded to municipalities by the Province in 1998.
This led to the creation of Ontario’s 47 Service System Managers, who are Consolidated Municipal Service Managers (CMSMs), or upper-tier (regional) and single-tier municipal governments across Ontario, and District Social Services Administration Boards (DSSABs) in areas where there are no regional municipalities in Ontario’s north.
Ontario is the only jurisdiction in Canada where municipal levels of government hold responsibility for social services.
By supporting, connecting, and advocating for our members across Ontario, we help them to achieve their collective mission of delivering the best human services outcomes for Ontario's communities.
OMSSA's Members are Ontario's 47 Service System Managers, including:
37 Consolidated Municipal Service Managers (CMSMs), or upper and single-tier municipalities across Ontario
10 District Social Services Administration Boards (DSSABs) in areas where no upper-tier municipality exists in Ontarios north
In Ontario, core social services like income support, child care and early years services and social housing are planned, managed and co-funded by municipal Service System Managers.
In the case of social housing, Ontario’s municipal governments fund the majority of costs as a result of the province transferring these responsibilities to municipal governments in 1998.
Within this unique landscape, Ontario’s 47 Service System Managers oversee systems planning and manage the delivery of local human services in a way that is integrated, people-focused and outcomes-driven.
Employment and income supports
Homelessness services and prevention
Child care, children’s and early years services
People remain at the centre, with a focus on the whole spectrum of a person’s needs
People can access a variety of services in one place, in the communities where they live
Services meet the different needs of Ontario’s unique communities (urban, rural or suburban, large or small, north or south) by leveraging Service System Managers’ in-depth knowledge of their communities
Services are planned, coordinated and delivered in a streamlined and integrated way, in coordination with local community supports
Services continuously improve through innovation, partnership and collaboration with local leaders in the health, education, justice, Indigenous, community development sectors and more
As accountable orders of government, municipalities work to ensure that taxpayer-funded services are managed with a focus on transparency, quality assurance and strong outcomes
