In 1999, an international competition was held to select an urban park design for a former military base in Toronto. This 320- acre federal park will provide natural and formal garden environments, offering both passive and active recreation while promoting such themes as environmental sustainability, new ecologies, and the rich heritage of the site. Contributors to this volume analyze the entries of the competition finalists and consider a range of issues raised by the competition, including landscape architecture, geography, landscape ecology, and contemporary urbanism.
