This thesis explores the potential contribution that could be made to core area revitalization through the integration of outdoor recreation planning, ecological planning, and urban planning. The revitalization of urban centres, and especially those of mid-size cities, has typically been explored through policy planning, economic vitality, and urban design. An area which often has been neglected is that of urban outdoor recreation, specifically recreation that is carried out in an ecologically compatible fashion. The thesis examines theoretical and practical approaches in outdoor recreation planning, ecological planning, and urban planning, addressing any gaps and insufficiencies that seem to hinder the integration of the three disciplines in practical terms. The core area in the city of Waterloo serves as a case study to examine the feasibility of integrating ecological planning, outdoor recreation planning, and urban planning. This research indicates that ecological planning is a versatile and responsive planning approach whereas outdoor recreation planning and urban planning seem disconnected from each other.
