The Regimental Senate of Princess Patricia's Canadian Light Infantry (PPCLI) was established as part of the 1977 revision of the regimental constitution. It consisted of PPCLI officers, active and retired, of the rank of Lieutenant-Colonel and higher; representatives of the PPCLI Association; and distinguished persons nominated by the Regimental Guard or the Regimental Senate. It was expected to meet at least annually, but was not required to record minutes. Its role was to provide advice to the Colonel of the Regiment. There is no evidence that the Senate ever actually met, and it became essentially an honorary body. It ceased to be active after 1986.
