An OMAA Recollection

On a Saturday morning in May of 1958, nine municipal administrators came together at the Royal York Hotel in Toronto to discuss forming a small association of chief administrative officers that would meet periodically and assist in the promotion of better local government. Thanks to founding members Brantford, Cornwall, Galt, Guelph, Kingston, Kitchener, St Catharines, Sarnia and Sault Ste. Marie, the "Municipal Chief Administrative Officials Association of Ontario" was formed--subsequently renamed the "Ontario Municipal Administrators' Association (OMAA)

OMAA Today

For over 55 years, OMAA members have been strengthening the quality of municipal government through professional management.

The Voice of Ontario Municipal Management and Administration

Today our association's membership base is approximately 200 of Ontario's Chief Administrative Officers (CAO), having collective responsibility for the administrative matters for municipalities representing 75% of the entire population of Ontario.

Members of OMAA hold the position within their municipality that exercises general control and management of affairs of the municipality, as set out within the Ontario Municipal Act. As such, the CAO members of OMAA are key decision makers and leaders in the direction of their municipalities, providing professional support for their elected officials and ensuring the implementation of Council policies.
