Master corporal

Master Corporal (MCpl) (French: caporal-chef or cplc), in the Canadian Armed Forces and the Royal Canadian Army Cadets is an appointment of the rank of Corporal in the Canadian Army and Royal Canadian Airforce. Its Naval equivalent is Master Seaman (MS) (French: matelot-chef or matc).

According to the Queen's Regulations and Orders:

(2) The rank of a master corporal remains that of corporal.
(3) Master corporals have seniority among themselves in their order of seniority as corporals.

Master Corporal, while formally an appointment, is treated as a de facto non-commissioned member rank, and is often described as such, even in official documents.

As mentioned above, the Master Corporal is senior to the Corporal (and its Naval counterpart, Leading Seaman). It is junior to the rank of Sergeant (Sgt) and its equivalent naval rank, Petty Officer 2nd Class (PO2). Master Corporals and Master Seamen together with Corporals and Leading Seamen make up the cadre of junior non-commissioned officers.
