Would you like to find out if a lot is contaminated? See the city’s list of sites.
List of contaminated lots
This list (in French) shows information about contaminated sites. It was compiled by the city, which is legally obliged to keep it updated. Residents, real estate professionals and buyers can easily check to see if a site is contaminated beyond regulatory values. Staff members who evaluate construction or allotment permit applications can also check the list.
If soil analysis shows that a lot is contaminated and an activity that could be considered polluting takes place there, a notice is added to the property assessment roll. However, all contaminated lots are not subject to such notice, as the Environment Quality Act only came into force in 2003.
The list of contaminated lots is not exhaustive. A lot that does not appear on it is not necessarily clean.
