United Counties of Leeds and Grenville

United Counties of Leeds and Grenville is an administrative region in eastern Ontario that extends along the Saint Lawrence River between Kingston and Cornwall. The territory encompasses multiple municipalities and rural communities within its jurisdiction.

This administrative territory was created in 1850 when Leeds County and Grenville County merged into a single governance structure. The consolidation established the foundation for how local administration functions in the region today.

The Brockville Courthouse, constructed in 1842, stands as one of Canada's oldest judicial buildings and contains the Themis statue, representing regional legal heritage.

The region provides municipal services and administrative functions distributed across several communities. Visitors seeking regional information can find offices and resources in larger towns like Brockville.

The counties maintain separate administrative relationships with three municipalities: Brockville, Gananoque, and Prescott, while including them for census purposes.
