總計建造12艘，哈利法克斯級巡防艦/城市級巡防艦，1975年加拿大巡邏巡防艦計劃（CPF），Halifax-class frigate

哈利法克斯級巡防艦 (Halifax-class Frigate) 為加拿大皇家海軍於1990年代入役的巡防艦，總計建造12艘，由於哈利法克斯級的艦名出處均為加拿大的城市，故又稱城市級巡防艦。
The Halifax-class frigate, also referred to as the City class, is a class of multi-role patrol frigates that have served the Royal Canadian Navy since 1992. The class is the outcome of the Canadian Patrol Frigate Project, which dates to the mid-1970s. HMCS Halifax was the first of an eventual twelve Canadian-designed and Canadian-built vessels which combine traditional anti-submarine capabilities with systems to deal with surface and air threats as well. All ships of the class are named after a major city in each province (St. John's, Halifax, Charlottetown, Fredericton, Québec City, Toronto, Winnipeg, Regina, Calgary and Vancouver) plus the cities of Ottawa and Montreal.
