HMCS Sudbury was a Flower-class corvette that served the Royal Canadian Navy during the Second World War.

[3][4][5] The "corvette" designation was created by the French as a class of small warships; the Royal Navy borrowed the term for a period but discontinued its use in 1877.

[11] When the U-boat threat spread to the North American coast and they began to target unescorted oil tankers, escorts were assigned to protect them against the menace.

In September 1942, she was placed under United States control and assigned to escort convoys between New York and Guantanamo until departing for refit in December.

[11] In January 1944, Sudbury was reassigned to the Pacific coast and arrived in February, where she immediately underwent a major overhaul.

[10][11][12] Sudbury entered civilian service and underwent several ownership changes by the early 1950s when she was acquired in 1954 by Island Tug and Barge of Victoria, British Columbia.

Sudbury towed the disabled vessel for 40 days through some of the roughest weather imaginable before arriving safely at Vancouver.

She was eventually badly damaged during repairs by a boiler explosion, the fireman on watch having lingered too long in a quayside pub, and thus the hull was dismantled for scrap in 1966 at Victoria, British Columbia by Capitol Iron & Metals and officially stricken in 1967.
