Ask for your water service line to be screened for lead

Last updated July 11, 2023

Would you like to know if your building has a lead water service line? Find out how to ask the city to perform screening.

A massive screening campaign for lead water service lines is underway across the city with a view to planning replacements. 

This annual program takes place from June to October. Affected residents receive a notice letting them know that the city will be coming to their home to test the water.

If you live in a building that is likely to have a lead water service line, you can ask for a home screening without waiting for the city’s notice.


To have your water screened for lead by the city, your building must meet both of the following criteria:

  • Have eight dwellings or fewer
  • Have been built before 1970


In order for your request to be reviewed, you must complete the form below and submit it by e-mail or postal mail. 

When the city receives your form, you will be contacted to plan a test at your home.
