About OMSSA

Who We Are

The Ontario Municipal Social Services Association (OMSSA) is a non-profit, non-partisan organization whose members are Ontario’s Consolidated Municipal Service Managers (CMSMs) and District Social Services Administration Boards (DSSABs). 

What We Do

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

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 Ontario’s 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.
