Trusted Professionals for Safe, Reliable, and Code-Compliant Service
In Toronto, many older homes are still equipped with outdated lead water service pipes, posing serious health risks to residents. Lead pipes, once commonly used for their durability, are now recognized as hazardous—especially for children and pregnant women. Replacing lead pipes with modern materials like copper or polyethylene is crucial to ensuring your household has access to clean, safe drinking water.
At Mister Plumber, our licensed professionals specialize in lead pipe replacement in Toronto. With decades of experience and state-of-the-art equipment, we deliver fast, reliable upgrades that meet all city and provincial regulations.
Why Replace Lead Pipes in Toronto?
Upgrading from lead service lines isn’t just a smart renovation—it’s a vital health and safety upgrade. Here’s why Toronto homeowners are choosing to replace their lead pipes:
- Safe Drinking Water – Eliminate the risk of lead contamination and protect your family’s health.
- Better Water Pressure – Modern pipes (typically ¾-inch or larger) allow for improved flow and consistent water pressure.
- Long-Term Reliability – Copper and polyethylene pipes are highly durable and resistant to corrosion, leaks, and bursts.
- Increased Property Value – Lead pipe replacement boosts your home’s marketability and resale value.
Lead Pipe Replacement Methods
We offer several efficient replacement methods to suit the unique layout and needs of your Toronto property:
- Traditional Trench Excavation
Best for difficult soil conditions, this method involves digging a trench to install the new water line at a depth of at least four feet to prevent freezing. - Trenchless Pipe Replacement (Torpedo Drilling)
A minimally invasive option that uses a pneumatic torpedo to bore a new path for the pipe underground, preserving your landscaping. - Hybrid Method
For complex jobs, we combine trenchless and traditional excavation methods to achieve the best results with minimal disruption.

Understanding the Lead Pipe Replacement Process in Toronto
Your water service line includes two segments:
- Private Portion: From your property line to your home—your responsibility as a homeowner.
- City Portion: From the property line to the municipal water main—maintained by the City of Toronto.
Toronto residents may qualify for the City of Toronto’s lead pipe replacement program. If you replace your private portion, the city may replace its portion at no cost. Our team will guide you through the entire process, including applications, utility locates, and scheduling.
Customized Upgrades to Meet Your Water Demand
While ¾-inch water pipes meet the minimum standard, larger diameters (such as 1” or 1.25”) are ideal for homes with higher water needs—especially those adding a basement apartment or planning future expansion. We’ll help you choose the right pipe size to meet your household’s present and future demands.

Frequently Asked Questions – Lead Pipe Replacement in Toronto
Q: How can I tell if my water service pipe is made of lead? I live in an older Toronto home.
A: Many homes in Toronto built before the 1950s may still have lead water service pipes. You can check in a few ways:
- Contact Toronto Water (dial 311) to request available records for your property.
- Book an inspection with a licensed plumber, such as Mister Plumber and Sewer Expert, for a professional assessment.
- Carefully scratch the pipe near the main shut-off valve—if it reveals a soft, shiny silver surface, it is likely lead.
If you’re unsure, it’s best to have a qualified plumber confirm the material safely.
Q: My lead pipe runs under my neighbour’s property, and they don’t want excavation. What are my options?
A: This is a common situation in older Toronto neighborhoods. A practical solution is to install a new water service line entirely within your property:
- A new copper pipe is installed and capped at your property line.
- You then apply for the City of Toronto’s portion of the replacement.
- Your contractor must clearly indicate that “relocation is required” on the invoice or documentation.
This allows Toronto Water to connect the new city-side pipe to your newly installed private line without disturbing your neighbour’s landscaping.
Q: My existing water line enters in the middle of the basement. Can a trenchless (torpedo) method still be used?
A: In most cases, no. For trenchless (torpedo) installation in Toronto:
- The water meter typically needs to be relocated to the front wall of the basement.
- The torpedo method is then used from the front foundation wall outward toward the street.
This approach helps avoid damage to underground drain pipes, which are usually located beneath the basement floor.
Q: What is the maximum distance for trenchless (torpedo) lead pipe replacement?
A: In Toronto, trenchless installations are typically effective for distances up to about 30 feet. However, this can vary depending on soil conditions and site access.
For longer front yards, contractors may:
- Create additional small access pits (for example, 3 ft × 3 ft), and
- Complete the installation in sections.
A site inspection will determine the most efficient and least disruptive approach.
Q: What preparation is required before replacing a lead pipe, and how long does the process take?
A: Proper preparation is essential for safe and compliant work in Toronto:
- Utility locates must be completed before any digging begins. This is typically arranged by your contractor and may take 5–10 business days.
- Once locates are cleared, the project can be scheduled at a convenient time. Many Toronto plumbing companies, including Mister Plumber and Sewer Expert, offer flexible scheduling, including weekends.
In most cases, the actual lead pipe replacement is completed within one day, from morning to afternoon.
