This badge is unique in that it was only used at the "Preferred Class Penitentiary (Ontario)" on Bath Rd. in Kingston as indicated by the "PCP" monogram at centre. Some confusion exists due to its small size. Despite it's being of the size commonly used for collar badges, photographic evidence confirms that it was, in fact, used as a cap badge. It was issued in cast gilt/brass and in stamped white metal versions, presumably to distinguish rank. As indicated, the gilt/brass examples are cast rather than stamped and have the manufacturer's identification, reading "J.R. GAUNT MONTREAL." stamped in an arc over "MADE IN ENGLAND" directly into the reverse of the lower ray.
This facility opened in 1930 and was intended to house "more reformable and physically fit" inmates. This unique designation only lasted for approximately 3 years. In March 1932 the facility was officially renamed "Collin's Bay Penitentiary" and was reclassified as a general population facility.
