Most bases and stations have three messes (officers', warrant officers' and sergeants', and junior ranks'). Many of these establishments have lodger units (such as air squadrons, army regiments, etc.) who also have their own messes. All of Her Majesty's Canadian ships have three messes aboard; this extends to Naval Reserve Divisions and other Naval shore establishments which bear the title HMCS (see stone frigate). Due to limited budgets and declining revenues, many messes have been forced to close or amalgamate: for example, at CFS St. John's, the junior ranks' mess of the Newfoundland Militia District closed, its members moving to the station's junior ranks'; the station's officers' mess and warrant officers' and sergeants' mess later amalgamated.
