HMCS SUMMERSIDE (MM711) is the second vessel to bear the name. It is named in honour of the former Flower class corvette HMCS SUMMERSIDE (K141).
HMCS SUMMERSIDE (K141) was a Flower class corvette that served the Royal Canadian Navy during World War II.
SUMMERSIDE was laid down at Morton Engineering & Dry Dock Co., Quebec on 4 October 1940 and launched on 7 May 1941. She was commissioned into the RCN on 11 September 1941.
On 29 October 1942 SUMMERSIDE along with HMCS ROSTHERN (K169) rescued survivors from the crew of the American tanker PAN NEW YORK which was torpedoed and damaged by U-624 in the North Atlantic 550 miles (890 km) west of Malin Head at 54-58N, 23-56W. Both warships sank the damaged tanker with gunfire and depth charges.
SUMMERSIDE assisted in escort operations during November 1942 as part of Operation Torch, the amphibious invasion of French North Africa in the North African Campaign.
Her forecastle was extended at Saint John on 25 October 1943.
The following spring, SUMMERSIDE was one of 57 RCN warships that participated in Operation Neptune, the code name for the Normandy Landings as part of D-Day (Operation Overlord).
On 18 January 1945, SUMMERSIDE completed repairs at Halifax.
She was declared surplus and decommissioned from the RCN on 6 July 1945. She was scrapped in June 1946 in Canada.
