Abstract: What difference, if any, does it make that women have reached the highest levels of political responsibility in Canada’s provinces and territories? In response to considerable public as well as academic interest in the question, this roundtable previews results from the first systematic assessment of the track records of women premiers – defined as leaders of constitutionally recognized, sub-national jurisdictions in the Canadian federal system. Guided by a larger international literature about gender and politics, the participants will analyze the impact of female political leaders across three provinces (Alberta, BC, PEI) and one territory (NWT). They will address executive influence by focusing on the following core question: How has women's leadership shaped the climate of political debate, the content of public policy, and the numbers of women in party, cabinet and civil service positions? In addition to evaluating this larger theme of the project, each contributor will consider women premiers in the specific context of their times and jurisdictions.
