P.V. type minesweeping trawlers.  Seven served as RCN minesweepers.  These ships were built before the First World War in the USA.  Initially constructed and used as fishing trawlers they were taken into service with the RCN during the First World War for patrol duty along the Atlantic coast.  They were each armed with a single QF 12-pounder gun.  Following the war they were returned to their original service.

HMCS TR 9.  Built at the Collingwood Shipyards Ltd., TR 9 was completed on 16 May 1918.  She was paid off on 15 Feb 1919, and sold in 1920.  She was renamed Somersby.

The Castle-class minesweeper was a highly sea worthy naval trawler adapted for patrol, anti-submarine warfare and minesweeping duties and built to UK Admiralty specifications.  Altogether 197 were built in the UK between 1916 and 1919, with 60 put in service with the RCN, and others built in India and later New Zealand.  Many saw service in the Second World War.  They were each armed with a single QF 12-pounder gun.  Early in the Second World War, ten Canadian-built trawlers that had been sold into commercial service after the First World War with a number of European countries, were captured by the Germans when they overran France, Belgium and Norway and taken into service with the Kriegsmarine.
