Lead Pipe Replacement in North York

Why lead matters

Water that stands against lead pipe, solder or brass can pick up lead. Health Canada has said no amount of lead exposure is considered safe, and young young children and pregnant people face the most risk. Toronto adds treatment to reduce corrosion, but replacing lead pipe removes the source.

Which homes may have it

In Toronto, lead service pipes were commonly used before the mid-1950s. Parts of North York developed earlier, including some streets near Yonge and older pockets in Lansing, Armour Heights and Downsview, may still have them. Homes from later decades are much less likely to, though older repairs and solder are worth checking.

• Check the pipe entering the house near the main valve
• Look for a soft, dull grey pipe with a bulb-shaped joint
• Ask for the city’s record on your service, if available

Replacing it

The service pipe has two parts: the city stretch from the watermain to the lot line, and the private stretch from there into your house. Replacing just one leaves lead behind. The City of Toronto has run a program to replace its portion when the private side is done and has offered financing options at times. Rules change, so check the current terms before planning.

1. Confirm the pipe material and coordinate with the city.
2. Replace the private portion with new copper or approved plastic pipe.
3. Install a new main valve inside and reconnect the plumbing.
4. Flush the system thoroughly once both portions are done.
