The ranks of inspector and higher are commissioned ranks and are appointed by the Governor-in-Council. Depending on the dress, badges are worn on the shoulder as slip-ons, on shoulder boards, or directly on the epaulettes. The lower ranks are non-commissioned officers and the insignia continues to be based on pre-1968 Canadian Army patterns. Since 1990, the non-commissioned officers' rank insignia has been embroidered on the epaulette slip-ons. Non-commissioned rank badges are worn on the right sleeve of the scarlet/blue tunic and blue jacket. The constables wear no rank insignia. There are also 122 special constables, as well as a varying number of reserve constables, auxiliary constables, and students who wear identifying insignia.
