The mandate of the committee was fulfilled in 2011. Documentation from the committee is maintained here to comply with direction provided by City Council on July 8, 9, 10 and 11, 2014.

During the dismantling of the east section of the Gardiner Expressway between 1999 and 2001, two sites in the vicinity of Leslie Street and Lake Shore Boulevard East were found to be contaminated with lead, hydrocarbons and other materials. The contamination is due to the historic industrial land uses in the area, the past use of leaded to gasoline and contaminants in materials used for landfill. The contaminated sites were capped and contained. Finally, the area was landscaped for bike trails and other recreational land uses.

The Gardiner East Contaminated Soil Monitoring and Review Committee was formed in April 2004 to review and monitor the performance of containment measures over time, and report their findings to the community. Monitoring of the sites was to ensure that contaminants remain in place and no risk is posed to the environment or the community.
