Service Line Warranties of Canada (SLWC) is a corporate partner of the Local Authority Services (LAS). LAS is a preferred provider of competitively priced and sustainable co-operative business services for Ontario municipalities and utilities, helping its customers “save money, make money, and solve capacity.” LAS was created in 1992 by the Association of Municipalities of Ontario (AMO).

As of 2021, SLWC partners with 70 municipalities and utilities in Ontario alone, providing water and sewer line repair coverage, in-home plumbing repair, and more to Canadian homeowners.

“The City highly recommends this service to other municipalities because it offers residents a low-cost solution to the problem of dealing with broken, leaking, clogged or even frozen water and sewer lines. We have received many compliments from residents for having made this service available to them. Even those who choose not to enrol in this optional program are better educated about their service line responsibilities, which is very important to the City.” – John Savoia, Financial Planning and Policy, City of Hamilton

Frequently Asked Questions


What would the warranty program cost the municipality or utility, and homeowners?
There is no cost to the city for this program, and homeowner participation is completely voluntary. For a small monthly fee, homeowners can purchase warranty protection that covers repairs to the buried lateral lines on their property. The SLWC Service Line Warranty and In-Home Plumbing Repair Programs provide generous repair coverage for the homeowner and royalty opportunities for the municipality or utility.

How does the program work?
SLWC handles all aspects of the program, including educational outreach, billing, customer service and contractor management and completion of all repairs to local code. SLWC even handles the mailing to homeowners in the community.

What happens when a homeowner experiences a service line break or leak on their property?
With one call to the Service Line Warranties of Canada toll-free number, a licensed contractor from the area will be dispatched to make the repair – usually completed within 24 hours. There is no paperwork to complete, no hidden service fees or deductibles, and no annual or lifetime limits on the number of repair occurrences. Contractors are thoroughly vetted through a third-party compliance management vendor that performs extensive background checks.

Why is the warranty program important?
Many people believe that water and sewer lines will last hundreds of years without failing, but the truth is, there are many reasons other than life expectancy of the pipes that contribute to infrastructure failure – such as tree root intrusion, rust and weather. The SLWC Service Line Warranty Program provides peace of mind to municipal homeowners and leadership.
