Population data refers to the number of active employees in organizations under the exclusive appointment authority of the Public Service Commission (PSC) (employees of organizations named in the Financial Administration Act — Schedule I, most of Schedule IV and some agencies in Schedule V). This differs from numbers reported by the Treasury Board Secretariat (TBS) that reflect employment in organizations under the Public Service Staff Relations Act. In addition, a number of separate agencies are subject to Part 7 of the Public Service Employment Act (PSEA), which administers the political activities of public servants. The population count represents the number of active employees at a specific point in time.
Population data are derived from the TBS Incumbent File. This file is extracted from the Public Services and Procurement Canada (PSPC) pay system.
