The cap badges, collar badges and shoulder titles worn by Provost officers and Other Ranks until the early 1950s were identical to those worn during the Second World War. In 1953, with the succession of Queen Elizabeth II to the throne, the design of the Royal Crown on cap and collar badges was changed from the Tudor (King's) Crown to the Saint Edward (Queen's) Crown. It would be several years before the new patterns were adopted, new and old patterns of insignia were worn concurrently.
With the adoption of Mess Dress, Patrol Dress, Summer Service and Combat Dress, new insignia for these uniforms appeared. These patterns of badges were worn well past Unification and were still commonly seen in wear in the early 1970s.
Special patterns of gilt, bronze, wire embroidered and plated cap badges were worn by officers. As well, officers commonly wore the Other Rank's pattern cap badges in the field and there is at least one known example of an Other Rank's collar badge worn as a cap badge by an officer on a green beret.

A new pattern of cloth shoulder title appeared in service about 1950. Similar in size and colour to the wartime titles, the post war pattern is distinctive in that the embroidered letters are taller and lack serifs. The top title in the illustration below is the postwar pattern, with a 1940's period title below for comparison.
Upon the adoption of the Combat uniform in the mid 1960s, a combat cap badge was approved and C Pro C combat titles were issued. Shoulder titles were worn on cloth slip ons on the epaulettes of the combat shirt and jacket. There were several minor variants of these titles, and one pattern was produced in error with the Corps designation misspelled.
Brass C PRO C shoulder titles were first introduced in the early 1950s for wear by all ranks. Subsequently, silver and gilt titles were authorized for officers. Metal titles were worn on the serge Service Dress, Tropical Worsted, Blue Patrols and Mess Dress. They were not worn on Battledress or the Combat or Bush Dress field uniforms.

In 1958, new patterns of trades badges were approved for all Army trades. The insignia chosen for the Service Police Trade was crossed flintlock pistols, a design originating with the American MPs, and accepted as the standard NATO symbol for Military Police. Although 4 "trade groups" or levels were authorized, only the first 3 were produced. Trade group 4 had so few qualified members that the badge was not manufactured. Members altered a group 2 badge by sewing a crown above it. These badges were worn only on Battledress and the Tropical Worsted (TW) uniforms.
The Disciplinarian trade had it's own pattern of trades badge depicting a rampant lion. Disciplinarians were carefully chosen Service Police Senior NCOs or Warrant Officers who were the training staff in dentention barracks.
A number of patterns of identification badges were produced, these were privately acquired, apparently primarily by plainclothes investigators in Quebec.
About 1949, Corps buttons were authorized and produced in 3 sizes. Kings Crown buttons were worn into the mid 1950s, when they were replaced by the Queens Crown version. Buttons were produced with brass, gilt or anodized finishes.
