This presidential address on Canada and the study of territorial politics makes four main arguments. The first is that territory is a central component of politics, especially of Canadian politics, and that it should remain a focal point of specialists of Canadian and comparative politics. The second is that territory matters in contemporary politics because it serves as grounding for political communities, their claims, and their politics. The third is that not “identifying” parts of Canadian politics as “territorial politics” risks overlooking the importance of territory in the theorizing of federalism, nationalism and regionalism. The fourth is that, through the case of Canada, political scientists have made significant contributions to the study of comparative territorial politics.
