HMCS Cape Breton (ARE 100)

Flamborough Head was transferred to the Royal Canadian Navy in 1952. She was officially renamed and recommissioned Cape Breton on 31 January 1953. Cape Breton was assigned to the Atlantic Fleet and homeported at Halifax, Nova Scotia until 25 August 1958 as a repair and training ship.[2] She had been acquired in an effort to expand the range of the fleet and to sustain operations against Soviet submarines deploying west.[9] In 1958 she sailed to Esquimalt, British Columbia where she was converted to an escort maintenance ship, she was recommissioned on 16 November 1959.[2] The conversion involved installing engineering and electrical workshops and the fitting of a helicopter landing platform.[10] Sea trials were performed in Magdalena Bay, Mexico in February 1960, returning to Canada in March after visiting San Diego.[11]

On 10 February 1964, Cape Breton was paid off into the reserve.[2] This was due to efforts to cut costs.[12] From there on, the vessel served as a towed support facility and accommodation vessel at Esquimalt under the designation Maintenance Group (Pacific). In 1993, she was replaced by a shore building. She was sold to the Artificial Reef Society of British Columbia (ARSBC) for use as an artificial reef.[2]

Except for a short section of the stern and her engines, the ship was sunk in the waters of British Columbia on 20 October 2001 by the ARSBC after extensive cleaning to meet Environment Canada requirements. The ship now lies near Snake Island in Nanaimo harbour for use as a scuba diving site.[2][7] Cape Breton sank upright to a depth of 145 feet (44 m). Her crow's nest reaches up to 40 feet (12 m) below the surface, the main deck lies at 100 feet (30 m).[13]

The stern was donated to the city of North Vancouver, British Columbia by the Artificial Reef Society. They placed it on display on the waterfront in 2001 with the plan to eventually develop the area into a maritime museum. However, those plans fell through in 2007 from lack of support. On 9 September 2013, the city council voted to dispose of the stern as the cradle upon which it was resting began to near the end of its life, and it was dismantled.[3][14]

The Christening Bells Project at Canadian Forces Base Esquimalt (CFB Esquimalt) Naval and Military Museum includes information from the ship's bell of HMCS Cape Breton, which was used for baptism of babies on board ship from 1959–1971. The bell is currently held by the CFB Esquimalt Naval & Military Museum, Esquimalt, British Columbia.[15]

Fleet Maintenance Facility Cape Breton was formed in 1996 at CFB Esquimalt from the amalgamation of three shore-based units: Ship Repair Unit (Pacific), Naval Engineering Unit (Pacific), and Fleet Maintenance Group (Pacific). Fleet Maintenance Facility Cape Breton took its name from HMCS Cape Breton.
