Integrated ecological and regional planning in a rapid-growth setting.

Toronto is among the fastest-growing urban regions in North America. Regional efforts to preserve rural landscapes and remnant habitat have had variable success. In the 1990s, significant conflict emerged over proposals to build large housing developments on portions of the Oak Ridges Moraine, a 160-km stretch of environmentally sensitive land along the city's northern edge. After years of planning conflict, Ontario's provincial government created the Oak Ridges Moraine Conservation Plan, an Act of the Ontario Legislature. The Plan represents a dramatic change in Ontario's approach to conservation planning. We examine the development and implementation of the Conservation Plan as an example of environmental planning policy in a complex urban setting. Data from interviews with policy actors, planning agency documents, and geospatial sources are used to construct an analysis and discussion of the Plan and its implementation. From a policy research perspective, the evolution and implementation of the Plan require analysis and monitoring to better understand how such approaches can best be implemented. The Conservation Plan marks a change in policy in Ontario, and the implementation process highlights challenges in putting conservation plans into practice.
