Coastal GasLink is creating an extraordinary legacy of safety and respect for communities and the environment. With construction underway, we want to make sure you have access to the information you need about our construction program. Coastal GasLink will be built using the safest, least disruptive construction methods that have been developed over the past three-quarters of a century. The 670-kilometre project is divided into eight construction sections, being carried out by our highly qualified prime contractors.

Construction updates

Construction notifications

Various pipeline construction activities will be shared with stakeholders through notifications. These include:


Blasting IconBlasting:
Blasting is done in the clearing phase of construction to break rock for excavation. All blasting activities are done in accordance with provincial and federal regulations.
Burning IconBurning:
As the right-of-way is cleared, timber is saved to be processed by the forest industry. Vegetation that is not suitable for repurposing, such as branches and shrubs, are burned in approved areas and on days permitted by local forestry burning rules in compliance with the provincial regulations.

Traffic Interruptions IconTraffic interruptions:
Construction activities that interfere with traffic fall within our notification guidelines.
drone-flight.pngDrone flight:
Coastal GasLink uses drones to survey route topography for clearing activities. Drones provide an efficient and unobtrusive way to view the project corridor including conditions and terrain. All drone operations are done in accordance with provincial and federal regulations.

Water crossing notifications

Coastal GasLink is constructing a pipeline that includes crossings of rivers and other water bodies. A typical work is a temporary bridge installed for construction and then removed after construction.

Where work at a crossing might affect navigation, even temporarily, Coastal GasLink posts a notice such as the ones below, to inform you of the application and planned work, and of where additional information can be found.

Transport Canada’s window for public comment is 30 days from the date a crossing is added to Coastal GasLink’s notification list.

Please submit any comments you have on a crossing application directly to Transport Canada on their website, using the Crossing ID file number listed in the notification list.

The right-of-way

The Coastal GasLink pipeline project right-of-way is approximately 45 metres wide during construction, and will be cleared of trees and brush.

Once construction is complete, the right-of-way will be maintained at approximately 32 metres in width to allow for operation, and to keep the area above the pipe clear of trees and branches. The width of the permanent right-of-way may vary depending on local requirements.

It is anticipated that the proposed pipeline will be buried under the ground for all of its approximately 670-kilometre length, except at specific locations such as fenced valve sites and compression stations.

The surface of the right-of-way is disturbed during construction to prepare a safe work surface and allow for digging the pipe trench. On agricultural land, topsoil is conserved prior to trenching to maintain land capability.

Coastal GasLink will take measures during and after construction to manage the potential for invasive plants and weeds.
