How to Identify Lead Pipes in Your Toronto Home
Lead pipes were commonly used for water service lines (the pipe connecting your home to the city water main) until the mid-1950s. Lead was banned for plumbing in Canada in 1975, but existing pipes remain in place unless replaced. Here's how to check:
Step 1: Find Your Water Service Line
Look where water enters your basement, usually near the water meter. The water service line is the pipe coming through the wall from outside. This is the pipe most likely to be lead.
Step 2: Identify the Material
Lead
- • Dull gray color
- • Soft - scratch reveals shiny metal
- • Not magnetic
- • Joints may be rounded/wiped
Copper
- • Brown/orange color
- • Hard - won't scratch
- • Not magnetic
- • May have green patina
Galvanized Steel
- • Gray color
- • Hard - won't scratch
- • Magnetic
- • Threaded connections
Step 3: The Scratch Test
Using a key or screwdriver, gently scratch the pipe surface. Lead is soft - you'll easily expose shiny silver metal beneath the dull gray exterior. Copper and galvanized steel are hard and won't scratch.
Step 4: Check the City Map
The City of Toronto maintains records of known lead service lines. Check your address at toronto.ca/lead. Note that records may be incomplete - many homes show "unknown" and require physical inspection.
Pro Tip: Two Pipes to Check
The water service line has two sections: city-owned (water main to property line) and private (property line to your home). Even if your private side is copper, the city side could still be lead. Both sections should be replaced together for maximum safety.
Health Risks of Lead in Drinking Water
Lead is a potent neurotoxin with no safe exposure level. While Toronto Water adds phosphate to reduce lead leaching from pipes, this is a mitigation measure - not a solution. Here's what you need to know:
How Lead Enters Water
Lead doesn't contaminate the water supply itself - it leaches from lead pipes, lead solder, and brass fittings as water sits in contact with these materials. Factors that increase lead levels include:
- Stagnation time: Water sitting overnight or during vacations has higher lead levels
- Water chemistry: Acidic or soft water is more corrosive to lead
- Temperature: Hot water leaches more lead than cold
- Pipe age: Older pipes with degraded protective scale release more lead
- Partial replacement: Disturbing lead pipes temporarily increases lead levels
Health Effects by Group
Children (Highest Risk)
- • Irreversible brain development damage
- • Lower IQ scores
- • Learning disabilities
- • Behavioral problems (ADHD-like symptoms)
- • Delayed growth and development
- • Hearing problems
Adults
- • High blood pressure
- • Kidney damage
- • Reproductive problems
- • Nerve disorders
- • Memory and concentration issues
- • Muscle and joint pain
Important: Boiling Doesn't Help
Unlike bacteria, boiling water does not remove lead. In fact, boiling concentrates lead as water evaporates. Filters must be NSF-certified for lead removal (look for NSF/ANSI 53).
Water Testing Options in Toronto
Testing confirms whether lead is actually leaching into your water and at what levels. Here are your options:
| Testing Option | Cost | Turnaround | Details |
|---|---|---|---|
| Toronto Public Health (priority) | Free | 2-4 weeks | For homes with children under 6 or pregnant women |
| City of Toronto program | Free | 2-4 weeks | Available periodically - check 311 |
| Private lab testing | $30-$60 | 5-10 days | CALA-accredited labs recommended |
| Home test kits | $15-$40 | Immediate | Less accurate - use for screening only |
How to Sample for Accurate Results
- 1. Let water sit overnight - Don't run any taps for 6-8 hours before sampling
- 2. Collect first-draw sample - Fill container from cold water tap without running first
- 3. Use provided container - Lab containers are sterile and sized correctly
- 4. Sample cold water only - Never test hot water (higher lead levels)
- 5. Kitchen tap preferred - This is your primary drinking water source
Understanding Results
- Health Canada guideline: 5 parts per billion (ppb) maximum acceptable concentration
- Below 5 ppb: Meets guideline but no lead level is truly "safe"
- 5-15 ppb: Action level - consider replacement, use precautions
- Above 15 ppb: Significant concern - prioritize replacement, use bottled water for drinking/cooking
Toronto's Lead Pipe Replacement Program
The City of Toronto offers one of Canada's most comprehensive lead pipe replacement programs. Here's how it works:
Program Components
City-Side Replacement (FREE)
When you replace your private-side lead service line, the city will replace their portion (water main to property line) at no cost.
- • Must be coordinated with private-side work
- • City schedules work around your contractor
- • Typically same day or next day
- • All excavation and restoration included
Private-Side Rebate (Up to $1,250)
Homeowners receive a rebate to offset part of their replacement cost.
- • Maximum rebate: $1,250
- • Application required BEFORE work starts
- • Licensed plumber must do the work
- • Permit required ($150-$200)
- • Inspection required for rebate approval
How to Apply
- 1. Confirm lead service line - Physical inspection or city records
- 2. Apply online or by phone - Visit toronto.ca/lead or call 311
- 3. Receive approval - City confirms eligibility (2-4 weeks)
- 4. Hire licensed plumber - Get quotes, choose contractor
- 5. Coordinate with city - Schedule work together
- 6. Complete replacement - Both portions replaced
- 7. Inspection - City inspects and approves
- 8. Receive rebate - Cheque mailed within 6-8 weeks
Important: Apply BEFORE Starting Work
Rebates are NOT available retroactively. You must have city approval before your contractor begins work. Starting early disqualifies you from the program.

- Net Cost: $2,425
What to Expect During Replacement
Lead pipe replacement is straightforward for most properties. Here's the typical timeline:
Week Before: Site Preparation
Contractor locates buried utilities, marks excavation area. City notified of scheduled work date.
Day 1 Morning: Excavation
Trench dug from property line to home foundation. Lead pipe exposed and cut at connection points.
Day 1 Midday: City Work
City crew replaces their portion. Brief water shutoff (30-60 minutes) affects your home only.
Day 1 Afternoon: New Pipe Installation
Copper pipe installed from property line to home. Connections made at both ends. Water restored.
Day 1 Evening: Backfill & Cleanup
Trench backfilled, compacted. Grass seed or sod placed. Work area cleaned up.
Within 2 Weeks: Inspection
City inspector verifies work quality. Rebate application finalized.
Pro Tip: Flush After Replacement
After replacement, run cold water taps for 5 minutes to flush any debris. Continue flushing taps for 30 seconds before drinking for the first week as the new copper pipe develops its protective layer.
Interim Protection Until Replacement
If you have lead pipes but can't replace them immediately, these measures reduce (but don't eliminate) lead exposure:
Daily Precautions
- • Flush before drinking: Run cold water 2-5 minutes first thing in morning
- • Cold water only: Never cook/drink with hot tap water
- • Use a filter: NSF/ANSI 53 certified for lead removal
- • Clean aerators: Lead particles collect in screen
For Families with Children
- • Use bottled water for infant formula
- • Get children tested - blood lead level screening
- • Consider pitcher filter for drinking water
- • Prioritize replacement - this is temporary only
Remember: Flushing Is Not a Solution
Flushing taps reduces but doesn't eliminate lead exposure. The only permanent solution is replacing the lead pipe. These measures are for the interim period while you arrange replacement - not a long-term strategy.

Frequently Asked Questions
How do I know if I have lead pipes in Toronto?
Check where water enters your basement - lead pipes are dull gray and soft (scratch with a key to reveal shiny metal). Copper is brown/orange and hard. The City of Toronto maintains a lead pipe map at toronto.ca/lead. Homes built before 1955 are most likely to have lead service lines.
What is the Toronto lead pipe replacement rebate?
The City of Toronto offers rebates up to $1,250 for private-side lead pipe replacement when coordinated with city-side replacement. The city replaces their portion (from water main to property line) at no cost to homeowners. Application must be submitted before work begins.
How much does lead pipe replacement cost in Toronto?
Private-side lead pipe replacement costs $2,500-$5,000 in Toronto. After the city rebate (up to $1,250), your out-of-pocket cost is typically $1,250-$3,750. The city-side portion is replaced free when coordinated.
Is lead in water dangerous?
Yes, lead exposure from drinking water is harmful. Children face the greatest risk - lead affects brain development, causing learning difficulties and behavioral issues. Adults face cardiovascular, kidney, and reproductive effects. There is no safe level of lead exposure.
How can I get free lead water testing in Toronto?
Toronto Public Health offers free lead water testing for homes with children under 6 or pregnant women. Contact TPH at 416-338-7600. For other households, private lab testing costs $30-$60.
Should I replace just part of the lead pipe?
Partial replacement is not recommended. When only part is replaced, disturbed joints can actually increase lead levels temporarily. The city and homeowner should coordinate to replace the entire line at once.
