The Royal Canadian Corps of Signals (RCCS, RC Sigs) is a corps of the Canadian Army. Major Wallace Bruce Matthews Carruthers established the corps in 1903, making it the first independent Signal Corps in the British Empire (before it would have been covered by the Telegraph Battalion of the Royal Corps of Signals). As a matter of honour, King George V, the Canadian monarch bestowed on the permanent force portion of the organization the right to use the prefix royal before its name. Thus the CSC became the Royal Canadian Corps of Signals while the militia component was redesignated the Canadian Corps of Signals on 1 Aug 1921.
