Lieutenant-colonel (Canada)

In the Canadian Forces, lieutenant-colonel (LCol, French: lieutenant-colonel or lcol) is a rank for officers who are in the Canadian Army or the Royal Canadian Air Force, equal to commander for officers who are in the Royal Canadian Navy. A lieutenant-colonel is the second-highest rank of senior officer. A lieutenant-colonel is senior to a major or lieutenant-commander, and junior to a colonel or naval captain.

The rank insignia for a lieutenant-colonel on air force uniforms is three 1-cm stripes of braid, worn on the cuffs of the service-dress jacket, and on slip-ons on other uniforms. On army uniforms, the rank insignia is one pip and a crown.

Lieutenant-colonels are addressed by rank and name and thereafter by subordinates as "Sir" or "Ma'am".

In the Canadian Army, lieutenant-colonels are often employed as commanding officers of battalion-sized groups, such as infantry battalions, armoured regiments, artillery field regiments, engineer field regiments, signal regiments, field ambulances and service battalions.

In the Royal Canadian Air Force, lieutenant-colonels are often seen as the commanding officer of flying or ground squadrons.

Note: Before unification of the Canadian Forces in 1968, rank structure and insignia followed the British pattern.
