Identify the pipe before pricing the risk
The direct answer is that a Toronto buyer should check the age and available water-service records, have a licensed plumber identify the private pipe, use the City's testing program when appropriate, and obtain a coordinated replacement plan before treating the issue as resolved. The City says lead service pipes may be present in houses built before the mid-1950s, but age alone does not prove the material or its current condition.
Start at the pipe entering the basement near the water meter. Toronto says a grey pipe that scratches easily and does not sound hollow when tapped may be lead, but recommends a licensed plumber for confirmation. Ask the seller for replacement invoices, permits, testing reports, notices and service cards. Contact 311 to request a City-record check; the City cautions that this can take up to 30 business days. Sam Kamra encourages buyers to begin early enough for records to inform the offer.
Separate the public and private portions
Toronto's service pipe has two ownership portions: the City owns the section from the street watermain to the property line, while the homeowner is responsible from the property line into the house. Evidence that one portion was replaced does not establish that the other is lead-free. Ask every invoice and City record to state which side, material and date it covers.
The City's Priority Lead Water Service Replacement Program allows eligible residents who commit to replacing their private portion to apply for priority replacement of the City portion. Program steps, contractor options and road-work restrictions can change, so confirm current eligibility and timing directly with the City before relying on the program in a closing schedule. The private-side cost remains the homeowner's responsibility.
Use testing as evidence, not a substitute for replacement
Toronto states that testing is the only way to know whether water contains lead and offers free residential lead testing through an accredited Toronto Water laboratory. Follow the City's kit, sampling and return instructions exactly. Record the sample date, tap, stagnation or flushing conditions and laboratory result; an informal hardware-store reading or visual pipe check is not equivalent.
A result represents the sampled water under those conditions, not a permanent guarantee about every outlet or future reading. Lead can also come from older solder, brass fixtures and interior plumbing. Ask a qualified professional and Toronto Public Health to interpret concerns, especially where pregnant people, infants or children under six may be exposed. Sam Kamra's practical property resources can help organize questions, and additional buyer preparation can support the broader decision file.
Plan safe interim steps and complete replacement
Replacement of the entire lead service is the lasting risk-reduction step. Toronto recommends coordinating the City-owned and private portions because cutting and replacing only one side can temporarily increase lead particles in drinking water. Obtain written scopes from licensed plumbers, including excavation route, restoration, permits, service size, timing, exclusions and post-work flushing or testing. Ask the lawyer how estimates, access, representations or agreed work should be addressed in the purchase contract.
Until replacement is complete, follow current public-health guidance. Toronto advises running the cold tap for at least five minutes after water has sat for a few hours and using cold water for drinking, cooking and preparing formula. Health Canada says a certified point-of-use filter can remove lead when installed, maintained and replaced as directed. Boiling addresses microorganisms, not dissolved metals, so it is not a lead-removal method. Confirm the current filter standard and any City support before purchasing.
Verify the handover after work
After replacement, retain the City application, contractors' invoices, pipe-material descriptions, restoration records and laboratory results. Confirm that both ownership portions are documented rather than relying on a new copper section visible inside. At the final visit, check accessible plumbing, pressure, leaks and restoration; route concerns through the professionals and lawyers.
Use the renovated Toronto home permit-records checklist when other plumbing or structural work needs verification. Public records are valuable when interpreted carefully; CB Herald's discussion of Sam Kamra and public LTB data illustrates that principle, while Barchart's report on the RealEstateBuyer.ca launch covers Sam Kamra's broader property-services work. The conclusion is simple: identify both sides, test properly and coordinate complete replacement. Bring the evidence to the plumber, City, lawyer and inspector before committing.
Questions and answers
Buying a Toronto Home with Lead Water Pipes FAQ
Which Toronto homes may have lead water service pipes?
The City says lead service pipes may be found in houses built before the mid-1950s. Age is a screening clue; records and a licensed plumber can help identify the actual material.

Does Toronto offer free lead testing for residential water?
Yes. Toronto residents can submit a sample for free lead testing through an accredited Toronto Water laboratory, following the City's current kit and sampling instructions.
