HMCS Lady Evelyn was a patrol vessel of the Royal Canadian Navy during the First World War, with a notable history both in military and civilian service. Originally constructed as a passenger liner named Deerhound, she was built in 1901 by John Jones and Sons at their yard in Tranmere, Merseyside. The ship measured 189 feet (57.6 meters) in length between perpendiculars, with a beam of 26.1 feet (8.0 meters) and a draught of 9.5 feet (2.9 meters). She had a gross register tonnage of 482 GRT and was powered by a triple-expansion steam engine driving two shafts, allowing a maximum speed of approximately 9 knots (17 km/h). Initially operated by the North Pier Steam Ship Company Limited of Blackpool, Deerhound was sold in 1905 to the West Cornwall Steam Ship Company, serving routes between Penzance and the Isles of Scilly. In 1907, the Canadian government purchased her for about $65,000, renaming her Lady Evelyn to serve as a mail tender for transatlantic steamers. Her role was to meet ocean liners in the Gulf of St. Lawrence, facilitating mail transfers to trains at Rimouski, Quebec, thereby expediting communication. She replaced an older vessel, Rhoda, in this capacity. Notably, Lady Evelyn participated in the rescue of survivors from the RMS Empress of Ireland after its sinking in 1914. During World War I, she was commissioned into the Royal Canadian Navy in June 1917 and assigned to the East Coast. Despite her limited maximum speed of 9 knots, she was tasked with seaward patrols against German U-boats and escort duties, although she was not suited for heavy seas. Her operational activity included dropping depth charges on a suspected submarine in August 1918 after sighting a periscope. She was present off Halifax during the December 1917 explosion and continued patrols until her decommissioning in 1919. Post-war, Lady Evelyn transitioned back to civilian service, being sold in 1921 to the Gulf of St. Lawrence Sg & Tdg Company and subsequently operated along the West Coast with the Union Steamship Company of British Columbia until 1936. She was eventually sold for scrap and dismantled at Bedwell Bay in late 1936. Her service life reflects her versatility, from passenger and mail service to military patrol duties during wartime, marking her as a vessel of significant maritime history in Canada.
