Map of lead service lines

Last updated June 19, 2023

Would you like to know if your home’s water service line is made of lead? Check out our interactive map and see the results of service line screening in Montréal.

Description

Results shown on the map are based on all screening operations of all known operations (screening, construction) being carried out by the city. 

For buildings that have not yet been screened, information is based on the year of construction (before 1970) and the number of dwellings (eight or fewer), two types of information that indicate that these buildings may have lead service lines. 

A great deal of information may be available for each water service line, depending on the progress of our operations.
