Mess dress uniform is the most formal type of evening-wear uniform used by military personnel, police personnel, and other uniformed services members. It frequently consists of a mess jacket, trousers, white dress shirt and a black bow tie, along with orders and medals insignia. Design may depend on regiment or service branch, e.g. army, navy, air force, marines, etc. In modern Western dress codes, mess dress uniform is the supplementary alternative equivalent to the civilian black tie for evening wear. Mess dress uniforms are typically less formal than full dress uniform, but more formal than service dress uniform.

Colonel is a Canadian Forces rank used by commissioned officers who wear the army, air force or special operations uniform. Captain(N) is the equivalent rank for officers who wear the navy uniform. A colonel is senior to the army and air force rank of lieutenant-colonel or the naval rank of commander, and junior to the army and air force rank of brigadier-general or the naval rank of commodore.
Full dress uniform, also known as a ceremonial dress uniform or parade dress uniform, is the most formal type of uniforms used by military, police, fire and other public uniformed services for official parades, ceremonies, and receptions, including private ones such as marriages and funerals. Full dress uniforms typically include full-size orders and medals insignia. Styles tend to originate from 19th century uniforms, although the 20th century saw the adoption of mess dress-styled full-dress uniforms. Designs may depend on regiment or service branch. In Western dress codes, full dress uniform is a permitted supplementary alternative equivalent to the civilian white tie for evening wear or morning dress for day wear – sometimes collectively called full dress – although military uniforms are the same for day and evening wear. As such, full dress uniform is the most formal uniform, followed by the mess dress uniform.
Before Unification as the Canadian Armed Forces in 1968, the Canadian military had three distinct services: the Royal Canadian Navy, the Royal Canadian Air Force, and the Canadian Army. All three services had a Regular (full-time) component and a reserve (part-time) component. The rank structure for these services were based on the services of the British military, the Royal Navy, the Royal Air Force, and the British Army. The change to a "Canadian" rank structure meant that many of the traditional (British) rank titles and insignia were removed or changed.
