The Royal Canadian Navy began planning the St. Laurent-class destroyer in the late 1940s and originally intended to procure fourteen vessels. Delays in design and construction saw the number of vessels for the St. Laurent class halved to seven. The seven remaining vessels were redesigned as the Restigouche class, taking into account design improvements found during construction of the St. Laurents. The seven ships of the class were commissioned between 1958 and 1959.
