[3] The title is derived from His Majesty's Ship (HMS), used in the United Kingdom, as the monarch of Canada is also equally and separately the monarch of the United Kingdom of Great Britain and Northern Ireland.
In the reign of a queen, the designation changes to Her Majesty's Canadian Ship; the French version of the title remains unchanged in this instance.
It was initially the only concession the British Admiralty made following the formation of the Canadian naval service.
[5] HMCS Haida became the first Canadian ship commissioned under a Queen during March 1952.
Shore maintenance and mooring facilities bear the name His Majesty's Canadian Dockyard (HMC Dockyard) (in French Arsenal canadien de Sa Majesté or Arsenal CSM).
