After the Korean War, on 13 September 1953, the PPCLI Association was incorporated. Branches of the Association exit across Canada and in Great Britain, each with their own executive overseen by the National Executive. The Okanagan/Thompson Branch, centred in Vernon, BC, was founded and organized in 1984 by LCol Vince Lilley. It serves members located in the Okanagan Valley and the Thompson River watershed in British Columbia.
During the Korean War, Princess Patricia’s Canadian Light Infantry was divided into three Battalions, each with its own Commanding Officer (CO) who operated autonomously within the Canadian military hierarchy. It became necessary to develop an organizational structure to administer the non-public property of the regiment, and to administer functions of the entire regiment, such as the Regimental Depot (later, Regimental Headquarters), the Regimental Museum, ceremonial events, the yearbook The Patrician, appointment of Colonels-in-Chief and Colonels of the Regiment, and maintaining the history and traditions of the Regiment. In accordance with terms of reference set forth by Western Command, the Regimental Executive Committee (known as the REC) first met on 30 September, 1952. It then drafted its own constitution. It was composed of the three COs of the battalions and a non-voting Secretary-Treasurer. It was later expanded to include the Regimental Major, the Regimental Sergeant-Majors of the three battalions, and a representative of the PPCLI Association. It was later expanded again to include representatives of extra-regimentally employed (ERE) members of the Regiment.
A group of Princess Patricia's Canadian Light Infantry (PPCLI) veterans living in Victoria, BC was represented at the inaugural meeting of the PPCLI Association in October 1947. The Victoria Branch was one of the components of the Association when it was legally incorporated in 1953. It was renamed Vancouver Island Branch in 2004.
