A ship travelling on the water.

HMCS Grou K518.

There has been only one vessel named Grou in the Royal Canadian Navy.

HMCS Grou (K518)

Far more habitable ships than the smaller corvettes, the frigates of the River class were also faster and had twice the endurance of the corvette. The Royal Navy frigates were named for rivers and hence known as the River class; the Royal Canadian Navy ships were named for towns and cities.

Grou was named for a French martyr of 1690, in lieu of the name Pointe-aux-Trembles, Quebec, the latter being considered overly long. Commissioned at Montreal, Quebec, on 4 December 1943, the River class frigate Grou arrived at Halifax, Nova Scotia later that month, worked up in St. Margaret’s Bay, and in March 1944 was assigned to Escort Group 6, Londonderry, Northern Ireland.

In April, she went to Russia’s Kola Inlet and returned as escort to convoy RA.59. Based at various times at Londonderry, Portsmouth, and Plymouth, in United Kingdom, she was present on D-Day providing anti-submarine patrol. Grou left for Canada with convoy ON.285 on 17 February 1945, and on 4 March began a six-month refit at Dartmouth, Nova Scotia.

Grou left for the west coast in October, and was paid off into reserve at Esquimalt, British Columbia, on 25 February 1946. She was broken up at Victoria, British Columbia, in 1948.
