Shoulder title Royal Canadian Signals (RC Sigs) brass

Major Wallace Bruce Matthews Carruthers established a militia (Non-Permanent Active Militia) component of signallers under the designation "Signalling Corps" on 24 October 1903, making it the first independent signal corps in the British Empire. It was redesignated "The Canadian Signal Corps" on 4 June 1913. On 1 April 1919 as part of the restructuring based on experiences during the Great War, a regular (Permanent Active Militia) component was established as the "Canadian Signalling Instructional Staff". This was redesignated "The Canadian Permanent Signal Corps" on 15 December 1920. Shortly thereafter, on 15 June 1921, King George V, the Canadian monarch, bestowed on the permanent force portion of the organization the title "The Royal Canadian Corps of Signals". Meanwhile, on 1 August 1921, the militia component was re-titled "Canadian Corps of Signals"; redesignated "Royal Canadian Corps of Signals" on 29 April 1936 (as part of the larger military restructuring that year); and finally aligned in nomenclature with the regular component as "The Royal Canadian Corps of Signals" on 22 March 1948, after the conclusion of the Second World War.
