The revitalization of formerly dark, dirty and often uninviting urban spaces is occurring across many cities throughout North America. This is because the hundreds of kilometers of laneways located behind buildings to be viewed as significant semi-public spaces and are being redeveloped into active spaces that can play a role in improving the state of the natural environment. The City of Toronto has a vast laneway system that is not being utilized to its full potential. This report attempts to demonstrate this point and suggests that there is an opportunity for recreating these laneways into vibrant spaces that support the natural environment while maintaining their primary functions as light vehicular thoroughfares and access points for homes and businesses. Through the examination of nine laneway redevelopment programs and projects this report highlights the successful techniques being implemented within these laneways and emphasizes the significant lessons that can be learned. Finally, each lesson learned is review, and recommendations are given on how the City of Toronto can potentially address each point if attempting to implement its own laneway redevelopment program. Among a host of recommendations, this includes the need to promote laneway redevelopment through a change to the City's existing land use planning policies; the development of laneway design guidelines; and, the implementation of a dynamic funding system.
