Members of the Pipeline Committee include the following underground pipeline companies: Valero Energy Inc., TQM Pipelines, Niagara Gas Transmission, Montreal Pipe Line Limited, Enbridge Pipelines Inc., Trans-Northern Pipelines Inc. and TC Energy.

The Committee’s mission is to convey a collective message regarding damage prevention that serves to ensure public safety as well as the integrity of the members’ pipeline systems.


As ambassadors for promoting damage prevention and safety, our interventions span over several activities and means to educate as many people as possible so that they may take the necessary precautions to work safely near pipeline facilities.

  • The presentation “Pipeline Safety: A Shared Responsibility” is aimed at employees working within various government entities (municipal and provincial), students who will become construction workers and companies that carry out work near pipelines. This presentation is carefully tailored to each group of participants and is offered either in person or by video conference.
  • Correspondence with contractors in civil engineering and excavation work as well as with the general public.
  • Provide free brochures: “Work Safely Near Pipeline Facilities/Map of Underground Infrastructures
  • Offer kiosks during exhibitions, trade shows, conventions, agricultural fairs, etc.
  • Provide tools for citizen communication that are adapted to municipalities.
  • Provide a permanent email address: [email protected]


As a member of Info-Excavation, we share the same concerns about safety and damage prevention. Every opportunity is taken to promote the use of our localization service. As such, anyone planning to carry out excavation or ground disturbance work within the prescribed area or using and operating vehicles or mobile equipment within the right-of-way are required to make a locate request.


In Quebec, member companies of the Pipeline Committee operate nearly 2,300 km of underground pipelines (gas and oil pipelines) which cross more than 250 municipalities. These pipelines carry high-pressure gas, which can reach 9,930 kPa (1,440 psi).

Their diameters vary, but the current largest pipeline has a diameter of 914 mm (36 inches). These pipelines are present in multiple areas (residential, industrial, commercial, forestry, agricultural, etc.), with the majority of these networks located on private land.


The prescribed area is a 30-metre area measured from the centre of the pipeline and extends on either side of the pipeline. It includes the pipeline’s right-of-way (the strip of land where pipelines pass). Certain activities done within this area require additional precautions. You must notify and obtain approval from the pipeline company prior to any ground disturbance activity.

Pipeline companies install line markers at road intersections, rivers, railways, etc. Line markers identify the general, but not exact location of underground lines. They serve to remind you that underground pipelines are located nearby. Furthermore, some line markers may have been damaged, moved, or even destroyed by third parties.

Only a representative from the pipeline company may locate a pipeline. Please note that work within the pipeline’s right-of-way requires the presence of the company’s representative throughout the activity.




Aimed at project managers/contractors in civil engineering and excavation work.

The breadth of pipeline systems means that many construction sites are likely to cross existing pipeline infrastructures. That is why our awareness campaigns are aimed at project managers and work providers from the following entities:

  • Hydro-Québec
  • Ministère des Transports du Québec et de la Mobilité durable (MTMD)
  • Municipal employees assigned to urban planning, public works and other related services
  • Vocational Centres
  • ACS Construction Site Foreman for Urban Infrastructures
  • DVS Heavy Equipment Operations
  • Association des entrepreneurs en drainage agricole du Québec (AEDAQ)
  • Association des propriétaires de machinerie lourde du Québec (APMLQ)
  • Contractors (construction and excavation)
  • Various stakeholders in the agricultural and forestry sectors
  • Various professional associations

General Public

RCMs and Quebec municipalities where pipelines cross their territory:

Consult the land register by RCM or by alphabetical order.


Municipalities are invited to publish our communication tools in their local media and to hand out our brochures to citizens whenever building permits are issued.
