Formally, there is a direct chain of command from the Queen of Canada to the governor general, through the Chief of the Defence Staff to all of the officers who hold the Queen's Commission, and through them, to all members of the Canadian Forces [REF].
Three military units comprise the Household Division, symbolically charged specifically with protecting the monarch and governor general: the Governor General's Horse Guards, the Governor General's Foot Guards, and the Canadian Grenadier Guards.
