With the adoption of the CF Green uniform came a unified system of rank insignia. The Army rank of Lance Corporal and it's RCN and RCAF equivalents were eliminated. A new rank of Master Corporal was introduced, while Staff Sergeants became Warrant Officers. Although the Sea Branch adopted the new insignia, traditional rank titles were retained. A Petty Officer might wear 3 chevrons and a maple leaf, but he was a Petty Officer 2, not a Sergeant.
Depending on the order of dress, rank insignia was worn on the jacket sleeves, shirt collars, epaulette slides and dark green brassards. The new rank system took several years to completely replace the old one, and it was common to see a mixture of new and old rank insignia in wear, especially in Reserve units.

The insignias for Private Pay Level 4A (a single chevron surmounted by a maple leaf) and Corporal (two chevrons, the top chevron bisected by a maple leaf) were authorized in 1969. An early or interim version of Master Corporal rank insignia consisting of two chevrons overlaid by a crown was adopted at about the same time. It appears to have been worn only on the Battledress and Combat uniforms. Contemporary literature describes the rank as either Senior Corporal or Master Corporal. By 1973, these insignias were obsolete and had disappeared from general wear.

In the mid 1980's, with the reintroduction of separate uniforms for the Land, Sea, and Air elements, rank insignia was again modified to reflect the changes. On the new DEU uniforms the Army retained the dark green backing, while the Air and Sea Elements adopted sky blue and black, respectively. Metal rank insignia was not worn on Air Force or Navy shirt collars and the rank insignia for the Combat and Work Dress uniforms remained unchanged. In the 1990s the term "Non Commissioned Member" (NCM) was adopted to replace the term "Other Ranks". "Non Commissioned Member" includes Warrant Officers, Non Commissioned Officers and Privates.

Metal rank insignia was adopted about 1970, but did not come into common wear until late 1971. Metal rank insignia was worn on both collars of the CF Green shirt and the CF greatcoat. Metal rank insignia was secured by two clutch pin fasteners, a special pattern with extra long pins was worn on the greatcoat collars. The first patterns of metal rank insignia for female members had a broach pin type fastener. This pattern was replaced by the standard clutch fasteners by the mid 1970s.

A pattern of metal rank badges with the insignia impressed on a disc exists. These were produced in very small numbers, likely as a trial prototype. Nothing more is currently known about these badges.

Cloth rank insignia worn on the CF Green jacket by Non Commissioned Officers was embroidered in "CF Gold" thread on a dark green backing. The insignia worn by Warrant Officers was embroidered in full colour. Initially, the rank insignia for female members was smaller and was embroidered in yellow thread, however the size distinction was discontinued in 1976.

Disposable rank insignia was adopted for wear on the NBCW Suit. The insignia consists of a thin cardboard patch about the size of a playing card. Rank insignia is printed in OG 107 and dull gold. A paper layer on the back of the insignia covers an adhesive backing.

Initially, the new CF rank insignia for the Combat uniform was identical to the existing army patterns. Because old pattern Army rank insignia was still in common wear in the 1970s the Warrant Officer's crown (identical to that of an Army Major) was doubled in size about 1975. This avoided confusion when the Warrant rank was worn on an epaulette slide, and the rank insignia was more visible when worn on the sleeve of the combat jacket. Around 1985, all NCO rank insignia was moved from the sleeves to epaulette slides. This was a short lived measure and was phased out after a few years. A relatively limited quantity of epaulette slides were produced with the rank insignia and national or unit designation embroidered directly onto the material.
Insignia worn on the Work Dress uniform was identical in pattern to that of the Combat insignia, but was embroidered in dull gold on a dark green backing.
