The Officers' Mess is used by both the Governor General's Foot Guards and The Cameron Highlanders of Ottawa (Duke of Edinburgh's Own). Originally constructed in the 19th Century for the officers of the Foot Guards, the mess was the scene of Sir Sam Hughes' (the Minister of Militia and Defence at the time) declaration of war by Canada in 1914. In addition to an extensive art and regimental silver collection, the mess also houses the current Queen's and Regimental Colours of both regiments.
