These vessels patrolled near Halifax and searched for mines laid by German submarines.

The Royal Canadian Navy hastily ordered 48 TR class trawlers (top) during the course of the war. To supplement these ships, the navy also purchased a number of American-built herring trawlers (bottom). Both types carried a bow-mounted 12-pounder gun as their main armament (bottom, at right on deck), and also carried a number of depth charges. Finding experienced sailors would prove more difficult than finding ships.
