"A spectre is haunting Europe and the United States--the spectre of immigration." So begins Robert Brym's introduction to this second volume of proceedings of the annual S.D. Clark Symposium. Contributors Richard Alba, Jeffrey G. Reitz, Naomi Lightman, Monica Boyd, Patricia Landolt, and Salina Abji consider the social and political effects and implications of immigration, both from a comparative perspective and with a specific focus on the Canadian experience in the early years of the twenty-first century. The result is a thought-provoking examination of one of the most important issues of our time. Immigration and the Future of Canadian Society gathers together the revised proceedings of the second S.D. Clark Symposium on the Future of Canadian Society. The Symposium, held each year by the Department of Sociology of the University of Toronto, honours the memory of S.D. Clark, the Department's first chair and one of Canada's leading sociologists of the twentieth century.
