Lead in drinking water affects homes built before the mid-1950s when residential water service pipes were commonly made of lead. Lead pipes were not used in apartment buildings or other multi-residential buildings with more than six units.
Water service pipes are owned by the homeowner and by the City (see this diagram).
Toronto Public Health strongly encourages residents in older homes with lead pipes to replace the entire pipe as the best way to reduce their exposure to lead in drinking water and to protect their health.
Lead testing is no longer a requirement to have the City replace its portion of a lead water service on a priority basis through the Priority Lead Water Service Replacement Program.
If you live in an older home and are still interested in getting your water tested for lead, please contact 311 to pre-register for your lead testing kit. Kits can then be picked up and dropped off at any of the below Toronto Public Health locations between 8:30 a.m. and 4:30 p.m.
The Toronto Water Laboratory will advise residents of their lead water test results over the phone and/or by mail.
