As of our most recent census data, racialized people comprise 22.3% of the Canadian population (Statistics Canada, 2016). Canadian universities have espoused commitments to diversity and inclusion but there has long been a gap between the rhetoric and practice. Research has demonstrated that under-representation is a problem at all levels of academia but particularly within the senior ranks. Drawing on an original dataset representing 324 senior university leaders, this study will empirically map the demographic composition of academic leaders across Canada, including presidents, vice-presidents, assistant vice-presidents, associate vice-presidents, provosts, and vice-provosts. Our findings suggest that racialized people in leadership are under-represented compared with their presence in the university population--consistent with the pyramid of exclusion where the representation of racialized people decreases as we move up the ranks. Taking a systems perspective informed by our critical ecology model we examine the overlapping societal-, organizational-, and individual-level mechanisms that impede the advancement of racialized people into leadership positions at universities in Canada.
