Deck Foundations Before You Dig

call before you dig

Call Before You Dig!

You should always call before you dig your deck foundations, if there is any chance something could be buried. Typically with deck buildingĀ projects being in the rear of a home, there usually won’t be any issues with buried utilities, but you never know for sure.

Safety Starts with You!

Before you dig, think about what services might be buried in the ground, becauseā€¦

What you canā€™t see can hurt you!

Itā€™s getting pretty crowded underground. There could be gas pipelines, electrical services, telephone and cable TV as well as water and sewer connections. In addition to these types of buried services to your home, there could be distribution networks for utilities that serve your neighborhood and community. In some cases, such as pipelines and fiber optic cables, they may even be part of a national feeder route.

Damaging underground services can have serious consequences:

Personal injury Loss of essential services, creating a safety risk for others. Expensive restoration costs and potential legal actions.

Thank you for taking the first step in damage prevention!

Ontario One Call provides a free service to excavators to make locate requests in the Province of Ontario. At Ontario One Call, our goal is to reduce damages to underground facilities and promote safe excavation practices through the operation of a state-of-the-art One Call Centre. For your convenience, the Centre is open 24 hours a day to receive your requests. Requests can be submitted through ourĀ online form, phone or fax. Emergency and short-notice (less than five days) requests may only be placed via phone.


The Right-of-Way

TransCanada approvals are required for heavy equipment crossing, construction, and excavation activities on or near our right-of-way (RoW) in accordance with your province or state. The RoW is a strip of land usually between 15 metres (50 feet) to 60 metres (200 feet) wide, and containing one or more pipelines. The RoW enables TransCanada to gain access to its facilities for inspection, maintenance, and testing purposes.

Before You Dig

Whatever the project, keep everyone safe by calling your local One Call CentreĀ at least three days in advanceĀ to learn the exact location of pipelines and other underground utility installations on your property.Ā  You will avoid costly repairs and interruption of vital services that can occur as a result of a line strike.

Before You Cross

TransCanada approvals are required for crossing over our RoW, to reduce the risk of pipeline damage and protect the public and the environment.
Companies, utilities, and landowners require approval from TransCanada to cross our facilities or conduct work within our pipeline RoW.Ā  If there is any planned work on your property, contact a TransCanada representative for a Crossing AgreementĀ at least two weeksĀ before crossing.
In Canada, please callĀ your local One Call Centre for all crossing enquiries; alternatively, you may send your request via e-mail toĀ
In the US, please contactĀ 811 for all crossing enquiries or contact TransCanada via e-mail atĀ

Before You Build

In Canada, for all development enquires within 200 metres of the pipeline or 750 metres of compressor stations, please contact TransCanada’s agent Lehman & Associates atĀ 1.866.602.0663.Ā  This includes, but is not limited to, permanent buildings and accessory structures such as pools, sheds, parking lots, decks, greenhouses, garages, and fences.
In the US, callĀ 811 three business daysĀ prior to any ground disturbances or excavation.Ā  A TransCanada Representative will meet with you to discuss your plans and attend any ground disturbance activities near or within our pipeline right-of-way.

Location of our pipelines

We use a variety of markers and signs along the RoW to clearly mark the general location of our pipelines.Ā  Markers are typically placed at any intersection or in heavily congested areas. However, pipeline markers should not be relied on for the exact location, path, or depth.
Our pipelines are buried underground at varying depths and the exact depth of cover can only be accurately determined by a TransCanada representative.Ā  For this reason, certain activities such as erecting structures and planting trees within the RoW are restricted until authorized by TransCanada.
Please call your local One Call Centre and, TransCanada will send a representative to your proposed excavation site to mark buried utilities at no cost to you.
