Lieutenant is a rank of the Canadian Army and Royal Canadian Air Force. The equivalent rank in the Royal Canadian Navy is sub-lieutenant. A naval lieutenant is one rank superior to the army rank of lieutenant and the naval rank of sub-lieutenant.
Lieutenants and sub-lieutenants are equivalent to ranks with a NATO code of OF-1.
The rank insignia of a lieutenant in the Canadian Army is two pips. In the Royal Canadian Air Force, the insignia is one 1⁄2-inch (13 mm) stripe with a 1⁄4-inch (6.4 mm) stripe above it. The rank insignia of a sub-lieutenant is a 1⁄4-inch (6.4 mm) stripe with one 1⁄2-inch (13 mm) stripe with the executive curl above it. On CADPAT and flying uniforms, the insignia is white on army slip-ons and dark blue on air force slip-ons.
The British pronunciation of the French word "lieutenant" (as "lef-tenant") is the official pronunciation as used by the Canadian Armed Forces, but the American pronunciation of "loo-tenant" (which is closer to the original French pronunciation) is sometimes heard in outside of the military.
Many Air forces of use a rank system similar to Armies, however, the RAF and the air forces of many Commonwealth countries, or those formerly under a British influence, use a different set of ranks loosely based on naval equivalents; Lieutenant, Commander, Captain and Commodore are prefixed for air force use with Flight, Wing, Group and Air, respectively (the first three being the units that they used to command).Comparative air force officer ranks of the Commonwealth
