The 87th Battalion, CEF was a Household Foot Guards infantry unit in the Canadian Expeditionary Force during the First World War.

The Canadian Grenadier Guards (CGG) is a reserve infantry regiment in the 34 Canadian Brigade Group, 2nd Canadian Division, of the Canadian Army. The regiment is the oldest and second-most-senior infantry regiment in the Primary Reserve of the Canadian Army. Located in Montreal, its main role is the provision of combat-ready light infantry troops in support of Canadian regular infantry. It is a Household Foot Guard regiment and also provides soldiers for public ceremonial duties, performing similar ceremonial duties as the Guards regiments of the British Army. This primarily entails mounting the guard at Government House, the King's and Governor General's residence, and performing the "Changing the Guard" ceremony on Parliament Hill in Ottawa, a task it shares with Canada's senior Household Foot Guard regiment, the Governor General's Foot Guards of Ottawa. The Canadian Grenadier Guards is an allied regiment to the British Grenadier Guards.
