Kanata South Ward or Ward 23 (French: Quartier Kanata-Sud) is a municipal ward in Ottawa, Ontario. Located in the city's west end, the ward created in 2006 includes the communities of Katimavik-Hazeldean, Glen Cairn, Bridlewood, and Trailwest. During a ward re-organization in 2006, the former Kanata Ward was split into two wards, Kanata North for areas north of Highway 417 and Kanata South for areas to the south.
