This case study is part of a collaborative series between the Canadian Institute for Climate Choices and the Smart Prosperity Institute exploring the value of urban natural infrastructure within the context of climate change and other economic, environmental and societal objectives. Other case studies in the series cover wetlands and urban forests.
