As the police service grew in officer strength, so did the complement of civilian staff dedicated to supporting the many facets of police service delivery. By February 1959 there were six members of the Kingston Police Department Clerical Staff: Mrs. Mary Bradshaw; Miss Mary Jackson; Mr. Adrian O’Sullivan; Mr. Edward Porter; Mrs. Patricia Conner; and Mr. Nicholas Timmerman. As employees of the Police Commission, in 1959 they sought and obtained affiliation with the Kingston City Police Association instead of the City Hall Staff Association for collective bargaining.
As demands on police operations became more complex, civilian staffing expanded to assume crucial roles in administrative support, records control, court liaison, property and evidence control, information technology, human resources management, financial administration, and crime analysis, as well as a myriad of tasks formerly performed by sworn members, such as dispatching, front desk reception and non‑emergency reporting, court security and prisoner transportation, and prisoner monitoring. By 2016 the Kingston Police operated with a civilian complement of 60 full-time employees and several part-time employees.
