The Public Service Commission of Canada (PSC) is responsible for promoting and safeguarding a merit-based, representative and non-partisan federal public service. As part of its oversight role, it undertakes investigations as well as audit and research activities to assess the integrity of the public service staffing system and its performance against intended outcomes. This study is part of these oversight initiatives and assesses the success of employment equity group members (women, visible minorities, Indigenous Peoples, and persons with disabilities) in seeking and obtaining promotions, relative to their counterparts.
