Canadians have a right to live in cities that meet their basic needs in a dignified way, but in recent decades increased inequality and polarization have been reshaping the social landscape of Canada's urban areas. This book examines the dimensions and impacts of increased economic inequality and urban socio-spatial polarization since the 1980s. Based on the work of the Neighbourhood Change Research Partnership, an innovative national comparative study of seven major cities, the authors reveal the dynamics of neighbourhood change across the Canadian urban system. While the heart of the book lies in the project's findings from each city, other chapters provide important context. Taken together, they offer important understandings of the depth and the breadth of the problem at hand and signal the urgency for concerted policy responses in the decades to come.
