Ontario One Call (ON1Call) was formed in 1996 to establish a call centre that receives excavation locate requests and notifies registered owners of underground facilities within the vicinity of the dig-site of the planned excavation. Ontario One Call became a Not-For-Profit corporation August 11, 2011, and the 'Limited' in its original name was discontinued accordingly.

Natural Gas Sewer Safety Inspections

Before any work starts to clear a blocked sewer beyond the walls of a building, it is very important that you or your plumber contact Ontario One Call.

It’s possible that some natural gas lines could intersect with sewer service lines. A serious safety issue may result if the tools used to clear the sewer service line damage a natural gas line, causing a gas leak.

Over the past ten years he has worked in the utility industry, serving in management roles in municipal relations, strategic planning and damage prevention.
