At 5 percent, Canada's population growth was the highest of all G7 countries when the most recent census was taken. But only a handful of large cities drove that growth, attracting human and monetary capital from across the country and leaving myriad social, economic, and environmental challenges behind. Quietly Shrinking Cities investigates a trend that has been largely overlooked: over 20 percent of Canadian cities lost population between 2011 and 2016, and twice that proportion grew more slowly than the national average. Despite a clearly uneven urban landscape, continuous, ubiquitous growth is considered normal, and policy and planning professionals have had little success in managing the practical challenges associated with population loss. Continuing rural-urban migration, declining birth rates, and an aging population only compound the worrying phenomenon of shrinking cities. Maxwell Hartt provides an empirical baseline of the geography and trends of urban contraction across the nation, and outlines the industrial and demographic processes that have led to a distinctly Canadian pattern of population decline. This meticulous work demonstrates that shrinking cities need to rethink their planning and economic development strategies in response to a new demographic reality, questioning whether population loss and prosperity are indeed mutually exclusive.
