Lead service lines
The service line is the pipe that brings water from the main to the building. In Montréal, buildings built before 1970 with fewer than eight dwellings may have a lead service line, and lead can dissolve into tap water.
The City runs screening tests and replaces the public part of the line; the owner must replace the private part. Our pages show the City’s test result where there is one; without a test, the risk is only estimated from the year built and the number of dwellings.
Before you buy, ask the seller whether the line was tested or replaced (invoice or City confirmation). A screening test is not an accredited lab analysis, and the line may have been replaced since.
