HMCS Cape Breton was a Royal Canadian Navy Cape-class maintenance ship. Originally built for the Royal Navy as HMS Flamborough Head in 1944, she was transferred in 1952. Upon her commissioning she was the second ship to bear the name Cape Breton. She served operationally from 1953–1964, when she was laid up. She was used as a floating machine shop until the late-1990s, before being sold for use as an artificial reef off the coast of British Columbia.

The Beachy Head-class repair ships were a class of 21 depot, maintenance and repair ships constructed for the Royal Navy during the Second World War. All of the ships in the class were constructed in Canada of which only five served in British waters during the war. Based on a modified mercantile design, five of the class were completed as merchant vessels after the war's end. Following the war, the majority were converted for mercantile use, with a further two ships ending up in service with the Royal Canadian Navy and another with the Royal Air Force.
