Water produced at the City’s drinking water treatment plants does not contain lead. Lead can be found in:

  • water service pipes in homes built before the mid-1950s
  • solder used to join pipes together before 1990
  • leaded-brass fixtures, such as faucets and valves

As these items corrode and breakdown, lead can enter drinking water.

Apartment and other buildings with more than six units do not have lead pipes, regardless of age. Lead is too soft to handle the pressure needed for these types of buildings.

Lead can affect how the brain and nervous system grows. According to Toronto Public Health, those most at risk include:

  • pregnant women
  • infants (in particular those who are fed formula made from tap water)
  • children under the age of six

Toronto Public Health strongly recommends replacing your side of the lead service pipe at the same time that the City is replacing its side. Cutting the pipe to replace just one portion can cause particles of lead to enter drinking water, which can lead to a temporary spike in lead levels.
