In the late 1940s there was a pressing NATO requirement for anti-submarine vessels, and funds were voted for seven destroyer escorts or frigates for the RCN. The British Whitby design was still on the drawing-boards and as the USN had nothing which met the exacting RCN Staff Requirement it was decided to design a new class of ship in Canada. Using the services of the Montreal naval architects, German & Milne, and under the direction of a senior constructor, Rowland Baker, seconded from the Director of Naval Construction, work started in 1949. Baker produced a design basically similar to the Whitby, but incorporating several ideas of his own. The machinery was identical with the British ships and St Laurent's was in fact imported from the UK, but electronics and electrical gear were of American and Canadian design. To flatter Canadian susceptibilities, Baker was careful to make the appearance as different as possible from the Whitby, but the ship which resulted was virtually a Type 12 specification (albeit with a different hull form) translated by a different design team.
