A ward is a geographic division of a municipality for electoral purposes, with each ward electing one or more councillors to represent that area on council. Ward systems ensure geographic representation—all areas of the municipality have dedicated representation rather than councillors all being elected city-wide (at-large). Ward boundaries are drawn to create roughly equal populations and may consider community identity, geographic features, and existing boundaries. Ward boundary reviews occur periodically to address population changes. Some municipalities use hybrid systems combining ward councillors with at-large councillors. Ward systems are common in Canadian municipalities, though some smaller municipalities elect all councillors at-large. Councillors typically focus on ward concerns while participating in city-wide decisions.
