The document discusses the lack of gender diversity in senior leadership roles in Canadian corporations despite 25 years of focus on advancing women. While women make up 48% of the workforce, only 36.5% of lower managers, less than 18% of top executives, less than 14% of boards, and 6% of CEOs are women. This lack of diversity represents a competitive disadvantage as research shows the most successful companies have diverse leadership that incorporates multiple perspectives. The authors argue that true change requires leadership that values diversity and holds teams accountable through transparent processes rather than just counting women or focusing on tactics. Leaders must uncover and address underlying biases to create lasting cultural change at all levels of an organization.
