HMCS Ontario was a Minotaur-class light cruiser built for the Royal Navy as HMS Minotaur (53), constructed by Harland & Wolff in Belfast. Laid down on 20 November 1941 and launched on 29 July 1943, she was transferred to the Royal Canadian Navy in July 1944 and commissioned as Ontario on 25 May 1945. Her construction featured typical cruiser design elements, with a displacement that allowed her to serve as a versatile platform for fleet operations. Following her commissioning, Ontario underwent workups on the River Clyde in Scotland before sailing to join the 4th Cruiser Squadron in the Pacific Theatre. However, she arrived too late to participate in active combat, instead engaging in operations at Hong Kong, Manila, and Japan. After the war, she returned to Esquimalt, British Columbia, arriving on 27 November 1945, where she entered refit and preparation for peacetime duties. Throughout the late 1940s and 1950s, Ontario participated in significant deployments and training exercises, including the largest postwar deployment of the Royal Canadian Navy to Pearl Harbor in October 1948, alongside destroyers Cayuga, Athabaskan, Crescent, and the frigate Antigonish. In 1949, she took part in the extensive training cruise with the aircraft carrier HMCS Magnificent and other vessels in the Caribbean, under the designation CTF 215. She also operated in Australian waters in 1951, participating in joint exercises with the Royal Australian Navy, and hosted members of the British Royal Family during the 1951 Royal Visit. Her service included a notable training cruise around South America in 1952, during which she suffered damage upon entering Buenos Aires harbor after being struck amidships by the merchant vessel SS Arauco, damaging her starboard propellers. Repairs were made in Rio de Janeiro before returning to Canada. She also participated in the Fleet Review for Queen Elizabeth II’s coronation in 1953 and conducted multiple overseas training cruises to Australia, New Zealand, Tonga, and Europe over the subsequent years. Decommissioned on 15 October 1958, Ontario was sold for scrap in Japan, arriving in Osaka for dismantling in November 1960. Her legacy persists through artifacts such as her ship’s bell, now held by the HMCS Ontario Cadet Training Centre and the Maritime Museum of British Columbia. The vessel’s name and history continue to be honored through the Ontario Sea Cadet Training Centre in Kingston, emphasizing her maritime significance as a symbol of Canadian naval heritage.
