Industrial Site Clean-up
Toronto, Ontario

Project Objective

The Metro Toronto and Region Conservation Authority sought to remediate a 12.5 hectare site in order to rezone as parkland.

Project Background

The FitonĀ  process was approved for use as a cleanup technology in Ontario. The process was reviewed by the Ministry of the Environment prior to the issuance of a Certificate of Approval. A Ministry of the Environment letter stated that, “the Fiton process can withstand fluctuations in pH and temperature and is particularly effective in treating petroleum contaminants from high concentrations down to the low parts per million (ppm) range.” E.B. Rodrigues, Ph.D. Coordinator, Environmental Cleanup Fund.

The Fiton process was used to remediate approximately 7000 cubic meters of contaminated soil in a 12.5 hectare parcel of land adjacent to the Don River in Toronto, Ontario, Canada. The site was contaminated with a variety of industrial chemicals including PAH’s, PCP, and petroleum compounds including benzene, toluene, ethyl benzene, and zylenes.

Remediation Objective

To meet Environment Canada guidelines for site remediation.


As a result of the cleanup, the site owned by the Metro Toronto Region Conservation Authority was rezoned from industrial to parkland use to increase the amount of useable green space in the city of Toronto while preventing further contamination of the Don River which flows into Lake Ontario.
