Ontario Small Urban Municipalities (OSUM) supports dozens of vibrant counties, small cities and towns that connect urban and rural Ontario. While no two communities are alike, small urban municipalities face shared challenges and opportunities that can be both urban and rural in nature. 

OSUM’s work is driven by an Executive Committee with members hailing from small single-tier cities, suburban towns, rural municipalities and counties. The Executive Committee all sit on the Association of Municipalities of Ontario (AMO) Board’s small urban caucus. OSUM’s advocacy work is supported by staff at AMO. 

Held each spring, the annual OSUM Conference held each spring is a significant opportunity for municipal leaders to come together, learn from experts, and work together to address the unique challenges facing Ontario’s small urban communities.
