Lead service lines in Montréal: check an address

In Montréal, buildings built before 1970 with fewer than eight dwellings may have a lead service line, the pipe that brings water from the street. Lead can dissolve into tap water. The City tests addresses and replaces the public part; the owner must replace the private part.

What to ask the seller

A screening test is not an accredited lab analysis, and the line may have been replaced since. More about lead service lines · To check an address, use the address search.
