This document discusses the gender pay gap and pay equity. It begins with definitions of key terms and then provides explanations for why the gender pay gap exists. It examines data on the size of the gap in Canada and internationally, comparing statistics across countries. Industries and occupations with larger gaps are explored, as well as barriers that prevent women from rising into leadership. The document then covers initiatives to address the gap through legislation, collective bargaining, and workplace policies and culture changes. Examples of recent pay equity cases from Ontario and Canada are also summarized.
