Many Canadian cities are faced with the challenge of contaminated lands that remain vacant due to high remediation costs. Redevelopment of these lots to green space enhances the character of our cities and improves human and environmental health. Phytoremediation, the process of treating contaminated soil and water with plants, was explored as a plausible design application towards the re-use of contaminated vacant lands. Based on an integrative literature review synthesis and a phytoremediation example, design guidelines were formulated and then applied to three Canadian municipal sites. An expert panel, including phytoremediation specialists and municipal staff involved with open space planning and development, provided an evaluation of the guidelines. The results demonstrated that the design guidelines are an appropriate foundation for the application of phytoremediation as an interim strategy for transforming contaminated lands into usable green space within Canadian municipalities.
