Lead in the water

Since 2013, Ville de Montréal has been sampling some twenty addresses on our territory on a yearly basis to test for the presence of lead, and to date no property exceeds Ministère standards.

This annual water sampling campaign meets the requirements of the Ministère de l’Environnement et du Développement durable under the Regulation respecting the quality of drinking water.

Which properties are concerned:

  • Buildings built before 1970 with up to eight dwellings
  • Buildings built between 1940 and 1950, commonly referred to as “post-war homes”

If your property meets one of the criteria above and you have not been contacted by the City since 2013 to be part of the sampling, you can contact us so that your property is added to the list for next year.

For a building with more than eight dwellings or a house built after 1970, it is very unlikely that the drinking water pipe connecting the house and the municipal water supply system is made of lead.

To know if you have a lead water service line, you can contact your landlord or a plumber; however, even if your water service line is not made of lead, an underground portion may be.

Aside from the service line, there may be other sources of lead in your plumbing; for example, welding, valves or accessories.

According to Québec government data, exposure to lead from drinking water is low and generally does not cause health problems in adults. Children under the age of six, including fetuses, are more sensitive to the effects of lead than adults.
