The Canadian Army also operates a summer public duties detachment known as the Ceremonial Guard, which assumes public duties in Ottawa from late-June to late-August. The Ceremonial Guard is made up of regulars or reservists of the Canadian Army, although its membership is also augmented by members regulars and reservists of the Royal Canadian Air Force, and the Royal Canadian Navy. Like the foot guards, the Ceremonial Guards also mount the guard of honour for military funerals, and visiting dignitaries while in season. Members of the Ceremonial Guard wear the uniforms of the Canadian foot guards, as they have historically staffed the summer public duties detachment, before membership in the Ceremonial Guard was opened to the entire Canadian Armed Forces in the 21st century. The Ceremonial Guard is considered an "ad hoc" detachment, as its members are drawn from various units of the armed forces, and does not constitute a permanent unit in the Canadian Forces' order of battle.
