Read the Coastal GasLink Project Overview

Indigenous engagement and consultation

The project route being built is fully permitted and is the result of rigorous fieldwork and consultation with Indigenous and local communities. Coastal GasLink adjusted its original routing through extensive consultation with Indigenous communities in the Morice River area near Houston, to protect sensitive cultural and environmental areas. Any significant change to the route at this stage would not allow the project to be successful.

We are in regular contact our Indigenous partners and communities along the project route. We have agreements with all 20 of the First Nations along the 670-kilometre project route, and we continue to receive strong support. We will continue to engage with all Indigenous and local communities as we progress this critical energy infrastructure project. This project is vital to British Columbia and Canada, including the 20 First Nation communities along the route who are benefiting from social and economic development this project offers and want to see it move ahead.

Coastal GasLink has the utmost respect for the First Nations system in British Columbia, whether that be elected or hereditary. It is out of this respect that we never made assumptions about who has decision-making authority. Instead, we strived to engage with all the Indigenous groups along the pipeline route—regardless of history or background—to ensure they’ve had opportunities to be part of our project planning process.

Since the project began in 2012, the Coastal GasLink team has engaged in a wide range of consultation activities with the Office of the Wet’suwet’en and directly with Wet’suwet’en Hereditary Chiefs. In fact, more than 1,300 phone calls and emails have occurred to discuss the project over the past six years, including approximately 120 in-person meetings specifically with Wet’suwet’en Hereditary Chiefs.

Coastal GasLink is proud of the relationships it has built over the past seven years. We appreciate the strong support we have received from Indigenous groups during this process, including through all 20 project and community agreements that have been reached with the elected Indigenous bands along the project route.

We will ensure that Indigenous communities are informed about our project and have opportunities to provide input on the project.

We are committed to building and maintaining positive relationships with First Nation communities and Métis organizations, and proud of the work we have done to work with all First Nations communities identified along our right-of-way. To date, the Coastal GasLink team has had over 15,000 interactions and engagements with Indigenous communities along the proposed pipeline route, and more than one-third of all the work completed on the project has been conducted by Indigenous people.

Our team has and will continue to ensure that Indigenous communities are informed and have opportunities to provide input to the project. We have worked with communities to understand their needs for capacity funding, and will continue to work with First Nations to ensure that their traditional land uses and traditional ecological knowledge are considered in our project planning.

We will ensure that Indigenous communities are informed about our project and have opportunities to provide input on the project.

Consultation with communities and stakeholders began early in the project development process. Since the announcement of the project in June 2012, Coastal GasLink engaged with 31 First Nations, two Tribal Councils and two Metis organizations, while focused consultation has taken place with 30 groups identified in the BC EAO Section 11 Order.

We’ve had over 15,000 interactions and engagements with First Nations communities about Coastal GasLink. Additionally, we developed and distributed information materials, including notifications of permit applications, and have advanced agreements to outline relationship protocols and capacity funding, as well as Traditional Knowledge sharing and participation in project activities and planning.

Throughout the engagement process with First Nations, we have held discussions and met on various subjects including the distribution and review of a draft ancillary site map outlining proposed features such as access roads, compressor stations, campsites, etc. contracting and employment opportunities; economic benefits; and routing of the proposed project corridor through each First Nation’s traditional territory. Our team members have attended community meetings to review the proposed project with community members. First Nations communities have actively engaged in our meetings, and participation on both sides has been productive, meaningful and respectful and positive.

The Wet’suwet’en community had an integral role in helping to shape the project from the very beginning. We’ve held over 120 in-person meetings with Wet’suwet’en Hereditary Chiefs and have had over 1,300 other interactions (calls and emails). We will continue to collaborate at every stage of the process.

Prior to the Environmental Assessment Certificate being issued, Coastal GasLink analyzed a number of potential routes. The analysis of these routes was shared with the Office of the Wet'suwet'en (OW) and the Hereditary Chiefs.

The analysis determined that the alternative routes were not feasible and therefore the route that was ultimately approved by the Environmental Assessment Office (EAO) was selected. Following the issuance of the EAC, and based on input from the OW and members of the Wet’suwet’en Nation, an alternate route was identified; the South of Houston Alternate Route (SHAR). Coastal GasLink applied for and received an amendment to the EAC for the South of Houston Alternate Route (SHAR).

Our collaborative approach with the Wet’suwet’en has been meaningful and informative. Our detailed discussions included field schedules, archeology programs, spatial files, stream crossings, wildlife and vegetation field data, technical reports and surveys.

Extensive discussions have taken place with the community regarding the selection of the proposed route. Additionally, we conducted joint socio-economic studies to identify potential cultural, social and economic impacts or benefits of the project. 42 Wet’suwet’en community members were thoroughly engaged on the project to better understand important sites for traditional activities.

Was cultural and heritage resource protection considered as part of the project development?

Coastal GasLink recognizes that B.C. is rich in cultural and heritage resources and we take our obligation to construct responsibly very seriously. The project’s environmental assessment was rigorous and included assessment for cultural and heritage resources and potential archeological sites. These studies were completed by qualified experts and involved field work that included participation from interested local First Nations.

Identifying and ensuring the preservation of artifacts – or other physical evidence of past human activity that may be of cultural heritage value or interest – was an integral part of the careful and proactive planning that went into this project. We have a Heritage Resource Discovery Contingency Plan in place that was developed in accordance with provincial regulations and reviewed and approved as part of the regulatory process to avoid or mitigate cultural heritage effects. 

Is Coastal GasLink aware of the oral history of the Kweese War Trail?

Early in project development process, Coastal GasLinked reviewed the Delgamuukw transcripts. This was done at the suggestion of the Office of the Wet’suwet’en (OW) and Hereditary Chiefs. The Kweese War Trail as described in the transcripts tells the story of the war party traveling to the coast and provides details on various places the party stopped along the way but does not provide a definitive trail location.

Earlier this year, the Office of the Wet’suwet’en provided Coastal GasLink with maps that they said identified the Kweese War Trail.  

While no evidence of this trail was found by a qualified archeologist in our pre-assessment, we nonetheless worked diligently to protect the areas identified on the maps provided, including the careful and planned avoidance of the specific areas of concern. The areas identified by the Office of the Wet’suwet’en remain intact and protected. We fundamentally disagree that any cultural values have been impacted based on the maps provided by the Office of the Wet’suwet’en. The area identified by the Office of the Wet’suwet’en has been protected and has not been cleared, contrary to claims of such.

What kind of evaluation was done on the Kweese War Trail?
Extensive study has been done in this location, in accordance with the applicable standards and practices using qualified archeologists and with the participation of interested Indigenous groups. This involved on-the-ground study in 2013, 2015 and again in 2019.

What protections are in place to protect the areas around the location identified as the Kweese War Trail?  
A number of measures have been taken to safeguard the area in the vicinity, including the placement of corduroy matting, which prevents disturbance to soils. These measures have been taken in consultation with the regulator and interested Indigenous groups. The Office of the Wet’suwet’en has not responded to invitations to participate in this process and we continue to welcome the opportunity to discuss this topic.

How has Coastal GasLink evaluated heritage and cultural resources for the project?

The Archeological Impact Assessment for the project was one component of the process for regulatory review, which was supported by more than 7,000 pages of documentation. The entire corridor was assessed using qualified archeologists and accepted methods of study, which included field work in which interested Indigenous groups participated. Certain locations were targeted for additional assessment and field study. The area in the vicinity of the location identified as a heritage trail was further studied this year.   

Information about how the AIA report was prepared is documented and available to the public under Heritage Inspection Permit 2013-0033.



Coastal GasLink has in place all major permits required to construct, including an Environmental Assessment Certificate (EAC).

The EAC was issued with a number of conditions, which have been satisfied with exception of certain work within the Morice River area as we were prevented accessing this area due to the previous blockade and we are working to satisfy the condition related to that area. 

As Justice Church noted in the injunction decision, Coastal GasLink tried unsuccessfully on multiple occasions to access the areas for the purpose of conducting the necessary field work to complete conditions.

“The plaintiff made repeated attempts to consult directly with Dark House and offered to provide information, discuss the concerns of Dark House regarding the Pipeline Project and ways to mitigate the potential impacts to Dark House territory. Dark House was invited to participate in the Environmental Assessment Office’s Working Group for the Pipeline Project but refused to do so.”

The original environmental assessment of this project, which was supported by a 7,000-page application and included thousands of hours technical and fieldwork, considered the potential effects of the project on the use of land and resources for traditional purposes, which included hunting, fishing, trapping and gathering.
The assessment considered these factors in the vicinity of the Healing Centre with available information at the time of the assessment. The assessment concluded there would be no long-lasting negative effects resulting from the project.

Coastal GasLink remains committed to ongoing dialogue and to working with Dark House (Unist’ot’en) to understand their concerns and wherever possible, address them. 

The full decision injunction is available here

The original environmental assessment certificate announcement is here

The B.C. government, through the Oil and Gas Commission (OGC) and Environmental Assessment Office (EAO) regulates approval of natural gas pipeline projects. There are a number of permits required for the pipeline and facilities construction. There are also local permits required for some of the work, depending on what and where the work is located.

Each of the OGC permits related to pipeline and facilities construction includes up to 70 conditions which will govern the implementation of the project related to:

  • Ongoing reporting to the regulator
  • Notification of affected parties during construction
  • First Nations engagement
  • Heritage conservation
  • Stream crossings
  • Land clearing
  • Wildlife
  • Terrain stability
  • Engineering

You can read more about permitting in this announcement.

Permit conditions are legal operational guidelines provided by regulators that direct Coastal GasLink on how it is to undertake pipeline construction and operation activities.

Permit conditions usually protect environmental, social and economic values that have been identified during the environmental assessment process as being important to protect and mitigate from potential impacts.

Some examples of permit conditions would be not to undertake water crossing construction activities during times important to fish for passage or spawning; not to undertake tree clearing activities during important bird nesting or migratory seasons and to provide potentially impacted communities, such as First Nations, with advance notice of activities in nearby areas.

Yes, regulators can amend permit conditions based on an application from Coastal GasLink or any other project proponent. Permit conditions generally cover larger than necessary time periods or areas and can, under certain circumstances, be amended to allow for construction activities to occur despite a permit condition having been ordered by a regulator.

The project has all the necessary permits for construction. Coastal GasLink was awarded an Environmental Assessment Certificate in 2014 in consideration of Indigenous and local community input, environmental factors, land use compatibility, safety, constructability and economics. This certificate was extended in Oct. 2019 for a further five years after having been thoroughly reviewed by the Environmental Assessment Office.

As stated on bclaws.ca, the Oil and Gas Activities Act prevents the Oil and Gas Commission from issuing a permit to convert an LNG facility pipeline into a pipeline for transporting oil or diluted bitumen. All of our studies, design, and construction are planned for natural gas transportation. Any future changes to the use of the pipeline would be subject to regulatory approval, including full consultation with government, local communities and First Nations, however there are no plans to convert this line to any other use. Coastal GasLink will also be bound by contract to provide natural gas for a minimum of 25 years, with numerous options to renew this service. The LNG Canada facilities, to which the pipeline will deliver natural gas, have no need for oil; they and the upstream natural reserves represent a significant capital investment and are expected to operate for well in excess of 25 years.


Information about site inspections and compliance is available from the Government of B.C.

Learn more compliance.

Coastal GasLink is in full compliance with the Environmental Assessment Certificate (EAC) and as of Nov. 19, 2018, has met all the required pre-construction conditions.

The project acknowledges that a warning of non-compliance was issued by the BC Environmental Assessment Office following an inspection last year. The inspection found Coastal GasLink was in compliance with 17 of 23 EAC pre-construction conditions. It was Coastal GasLink’s understanding that certain work required prior to construction, such as geotechnical earthworks or the placement of monitoring wells typically and routinely done in advance of construction, was appropriate. The inspection has since clarified that these activities fell under the definition of construction.

Coastal GasLink has since satisfied all the conditions and is on track with pre-construction and construction activities.

With the successful announcement of a Final Investment Decision (FID) by our Joint Venture Partners, the Coastal GasLink project needs access to the Morice River bridge and a public access road to begin construction activities. For the Coastal GasLink team, this decision was not taken lightly. Unfortunately, it has become a last resort and a necessary action in our efforts to safely gain access to the Morice River Bridge, after years of attempting to engage the blockade to work through a solution.


No. The location of our recent construction-related activities is 17 kilometers from the camp. Coastal GasLink has established and permitted work sites, which were surveyed in mid-January to delineate boundaries. Our crews have been working in an area that was previously cleared and their focus has been on site preparation and rough grading for placement of the housing units.

Additionally, safety of our people and those in nearby communities is paramount and we will have measures in place to ensure camp rules are followed.

Coastal GasLink makes every effort to notify surrounding communities when new construction work begins in a specific area.

Any work that occurs on an active construction site is accessible to authorized personnel only. to ensure awareness and to prevent any disturbance to traditional.

Construction activities started in January 2019 following a positive Final Investment Decision (FID) by the joint venture partners of LNG Canada (our pipeline customers). As of early 2022, construction on the project is now more than 60% complete. Please visit our construction update to stay up to date on project progress.

The pipeline will be buried at a depth of approximately one (1) metre, and the project will include the construction of some above-ground facilities. For example, meter stations measure the volume of natural gas moving through the pipeline. Compressor stations are used to increase the gas pressure to transport the gas through the pipeline.

It is expected that the pipeline will require one compressor station at the start of operations. As many as seven could be added along the corridor in the future, depending on the volume of natural gas needing to be shipped.


There are no plans to convert this line to any other use. All of our studies, the design, and construction are planned for natural gas transportation, and the pipeline would not be suitable to transport oil. Coastal GasLink will also be bound by contract to provide natural gas for a minimum of 25 years, with numerous options to renew this service. The LNG Canada facilities, to which the pipeline will deliver natural gas, have no need for oil; they and the upstream natural reserves represent a significant capital investment and are expected to operate for well in excess of 25 years.

In addition, any future change to the use of the pipeline is subject to regulatory approval, including full consultation with government, local communities and First Nations.


No. The blockade was on a small area of the route, and construction is proceeding on over 30 work fronts across the 670-kilometre project route with over 1,000 women and men at work. We are focused on resuming construction in this small area as soon as the road is cleared of snow and fallen trees.

For further information about this issue, we recommend reading the 'What's New' section of the Coastal GasLink website, beginning with this post.  


The COVID-19 pandemic continues to evolve with the rapidly-spreading Omicron variant. Coastal GasLink’s contractors and operators have implemented an enhanced COVID-19 Management Plan, based on guidance from provincial and local health authorities, to help mitigate and manage the spread of COVID-19. The measures in place have been reviewed and approved by Northern Health and meet all of the Provincial Health Officer’s guidance to help keep our workers, their families, and local communities safe.

Some of the measures in place include:    

  • Mandatory masks for all workers when not alone 
  • Workers must stay apart and abide by all local restrictions 
  • Enhanced pre-screening (asymptomatic testing)
  • Increased sanitization throughout sites and accommodations 
  • On-site screening
  • On-site 24/7 medical service 
  • Support for workers who have to isolate 
  • Strict consequences for not adhering to the measures, including dismissal 

Working together, Coastal GasLink’s contractors, operators and workforce can safely minimize and manage the risk of COVID-19 transmission at our worksites and help protect the safety of workers and local communities.



Coastal GasLink has a proactive screening program in place at all of our workforce accommodations, with the support of our medical services provider, International SOS, and our medical experts at Iridia Medical.  Every worker newly-arriving to site must be tested. They will also be tested if they’ve been away from site for more than 72 hours or workers moving between lodges.  Those who refuse COVID-19 testing will not be permitted on work sites or in workforce lodges. Testing is done using the Rapid Antigen Diagnostic (RAD) method, providing results within 30 minutes. Testing our workforce is a critical component of Coastal GasLink’s enhanced COVID-19 Management Plan. Together with other measures, like mandatory mask use, screening provides us with a comprehensive approach to minimize the spread of the virus, and helps protect our workers and nearby communities. Initial testing will be done using Rapid Antigen Diagnostic (RAD) testing.  



In line with the public vaccination program, vaccines will not be made mandatory. However, Coastal GasLink strongly encourages all workers who are eligible to be vaccinated to do so.

We provide workers with fact-based information on the vaccines so they can make an informed decision. Vaccination clinics have been available across the project since 2021 for easy access, and will continue to be offered.


Vaccines and testing provide us with an important layer of protection, but until directed otherwise by Northern Health and the Provincial Health Officer, all Coastal GasLink workers will continue to be required to abide by the protocols in place regardless of testing and vaccinations

As per the guidance of Dr. Bonnie Henry, Northern Health, and our medical experts Coastal GasLink requires strict adherence to COVID-19 measures, such as wearing masks, staying apart, testing, and proper hygiene which provide a strong foundation in preventing the spread of COVID-19. Failure to comply with health and safety requirements may result in removal from the project.

Our immediate concern is for the health and safety of our workers, their families and local communities. That’s why detailed protocols are in place at every worksite and accommodation to proactively identify and respond to potential cases of COVID-19. As required in the provincial guidelines, individuals receiving a positive test or exhibiting symptoms suggestive of COVID-19 are required to inform their employer so self-isolation and contact tracing procedures can be immediately implemented. These protocols are in place across the project are followed in close collaboration with Northern Health to help mitigate and manage the spread of the virus.


Our Health and Safety team has collaborative relationship with both regional and provincial health officers, as well as WorkSafeBC and Emergency Management BC. We are participating in ongoing dialogue and strategy sessions with these agencies to share information about our operations, and to make sure that Coastal GasLink has the most current information with which to be prepared every step of the way. We are actively implementing all guidelines directed by government and health authorities and will continue to adjust our operations as new information emerges.

COVID-19 is a global challenge, and businesses small and large have had to adapt. We are fortunate to work with a team that is going above and beyond to protect the health and safety of their coworkers, families, and communities. The long-term impacts to the overall schedule continue to be assessed and we are focused on delivering this project with our prime contractors, Indigenous and local community partners in a safe and efficient manner. We are committed to continuing to keep our local and Indigenous partners informed, as more clarity on the plan is understood.

Coastal GasLink is vital to the long-term prosperity of the North, B.C. and Canada, and we are proud to be part of a healthy economic recovery that supports local communities for the long-term. Above all else, we will always prioritize the health and safety of people while striving to achieve our commitment to creating an extraordinary legacy of safety and respect for all people, communities and the environment.



Coastal GasLink is committed being transparent and providing communities with information on the project and its COVID-19 management efforts.

Together with our medical advisor, Dr. Allan Holmes, we provide regular COVID-19 updates as a platform for Indigenous and local leaders to get the latest project information and ask questions.

Information about health & safety measures being implemented across project sites is also available on our website, together with regular updates on our number of workers, active cases and total cases to date are also available. This information can be accessed at CoastalGasLink.com/safety.

Another way that we are supporting local communities is through partnering with local organizations like the United Way of Northern B.C. Our donation of nearly $100,000 to their COVID Relief Fund, will help support vulnerable populations like seniors and those in need, living in communities across our project area (read more here). We will continue to work together with local communities and our First Nations partners to understand local concerns so that we can be part of building strong and vibrant communities for the long term.


Safety is, and always will be, our number one value. From design and construction, to operation and maintenance, we are committed to keeping Coastal GasLink and your communities safe.

We do not compromise on the health and safety of our workforce. Safety is a fundamental value not just in our field operations, but also in our offices and boardrooms. 

A key component of our strategy to keeping health and safety top-of-mind around the clock is our commitment to a positive safety culture. Before a worker even sets foot on-site, they’re thoroughly trained on the health and safety requirements of the project. Every worker undergoes a stringent safety orientation program and understands that we have zero tolerance for any kind of behaviour that endangers the health and safety of our workforce.

By continually modelling and reinforcing safe practices on our worksites, we’re successfully working towards a goal of zero workplace incidents.

We use high-quality steel and the best construction practices when building pipelines. All pipe is tested well above normal operating pressure before it is put into operation. Our pipelines are cathodically protected, which means a low-voltage electric current is induced in the vicinity of the pipeline to inhibit external corrosion. Pipelines are monitored 24 hours a day by trained operators who respond immediately to any indication of abnormal operation.

Cleaning and inspection tools called “smart PIGs,” are pushed along inside the pipeline using the pressure of the natural gas itself. These tools help assess the pipeline’s integrity and gathers data that shapes our pipeline maintenance programs.

If anomalies are detected, the pipeline segment in question may be excavated and visually inspected for repair or replacement. The project route will also be patrolled on the ground and from the air.

Every year, TC Energy invests millions of dollars in preventive maintenance and integrity programs that help us proactively identify and upgrade the safety systems of our infrastructure network.

Learn more about pipeline safety.

Pipelines like Coastal GasLink are the safest method to transport natural gas over considerable distances. While we take every possible safety precaution, we also must be prepared to respond if there’s an incident on our pipeline.

The process used at TC Energy for emergency response is the “Incident Command System (ICS)”. This allows for a unified command approach, where TC Energy works directly with federal, provincial, local and aboriginal authorities to develop common objectives and action plans to address emergencies. If an emergency occurs, we immediately confirm the exact location of the emergency and identify affected facilities. Valves spaced at intervals throughout the pipeline system shut off the flow of gas and allow the location to be effectively isolated. We work closely with local emergency service groups, regulatory agencies, landowners, community officials, and the media throughout any incident.

Coastal GasLink has prepared a comprehensive Emergency Response Plan that outlines procedures to protect the public, emergency responders, property and the environment in the unlikely event of an emergency. Detailed analyses of emergency response scenarios also help us determine where and how to locate resources that will allow us to respond as quickly, and effectively as possible during potential emergencies.

In addition, our prime contractors will be required to submit safety plans that address emergency procedures aligned with our health and safety expectations. Our prime contractors may also undertake their own emergency exercises or simulations during construction.

Natural gas is one of the world’s cleanest and safest energy sources. It is a naturally occurring gas mixture consisting primarily of methane, but may also contain other valuable products such as propane and butane. It is lighter than air, which means should a leak occur, natural gas dissipates into the air. Exposure to low levels of natural gas is not harmful to people, the environment or wildlife.

The Coastal GasLink pipeline will be monitored from our state-of-the-art control centre 24 hours a day, 365 days a year using satellite technology and sensors within the pipeline. As with all large infrastructure, there are still various situations that could pose risks to a pipeline, and in turn, the public, our workforce, and the environment.

The biggest risk to a pipeline is when unauthorized activities or excavation is conducted on the project route. Any of the following activities require written consent from TC Energy. Failure to obtain written consent can result in serious consequences.

  • any ground disturbance within 30 metres of the centerline of the pipe;
  • construction of a facility on a pipeline right-of-way; or,
  • vehicle or mobile equipment crossing the pipeline right-of-way.

Always call before you dig and help keep yourself, your community and the pipeline safe.

There are no routine gas emissions from compressor stations. Any venting at the station would only be done under controlled conditions for pipeline and station maintenance or as a result of a pipeline emergency. There are no flare stacks proposed for our compressor stations and little to no gas emissions. TC Energy is recognized as a leader in greenhouse gas emissions management, with particular emphasis on methane emissions management programs.

Noise levels are regulated and will be at or less than 40 decibels at all areas within 1.5 km of compressor stations. Noise levels will be routinely monitored to ensure they remain in compliance with the appropriate local regulations. We engineer stations to minimize the noise impact to the surrounding areas, including silencers and noise attenuation on the buildings. We also contain our turbo compressors within acoustic enclosures inside our compressor buildings. The compressor buildings themselves are purposely built to further ease noise levels. Our teams work diligently to ensure noise levels are no more than 45 decibels at our station fence line. This is equivalent to the sound of a refrigerator humming or a running stream, and is consistent with normal background noise in the area. As a point of comparison, normal conversation at one metre is 60 decibels.

Our compressor stations are unmanned and facility lights are shut off at night (except for safety lights over doorways) unless there are maintenance activities being conducted.

Driving over a pipeline can damage the integrity of the pipe over time, potentially leading to weakness or corrosion in the pipeline. That’s why, road, highway and other common crossings have been designed with weight loads, traffic frequency and depth in mind. We often use thicker pipe, deeper installation, or other mitigating measures to reduce impact to the pipe in areas that may see more frequent crossings. For everyone’s safety, it is important to always contact us if you need to drive equipment or heavy loads over a pipeline right-of-way that is not part of a highway or public road.

If you need to cross the pipeline right-of-way, simply contact TC Energy's crossings team, and we will work with you to find a way to do so safely. You might only be driving over the pipeline once or twice, but for a pipeline designed to last decades, each incident adds up, eventually comprising the safety and integrity of the pipe. Help keep the pipeline and the community safe, and make sure you get approval from TC Energy’s crossings team.

Project benefits

We will create jobs and contracting opportunities to benefit northern B.C., the province and the Canadian economy. Jobs will span a wide range of skill levels and trade specializations, with the greatest demand occurring during the construction phase of the project.

We will employ qualified and economically competitive local contractors and support services where practical. Examples of contracting opportunities may include: equipment rentals and purchases, fuel supplies, construction materials, accommodation and food services, helicopter and aircraft rentals, and more.

We anticipate that 2,000 to 2,500 short-term jobs will be created on our pipeline project, which will bring millions in economic benefits to local communities. In addition, approximately 16 to 35 permanent field positions for operations and maintenance will be maintained once the pipeline is operational. While long-term pipeline-related jobs will be small in relation to construction jobs, the long-term, ongoing economic benefits to local communities will be substantial, including investment in local communities through our community investment partnerships and our education and training plan.

Indigenous people are already benefiting economically from our northern B.C. pipeline projects, participating in tens of thousands of hours of environmental field work as advisors, technicians and support employees. In fact, to date, more than one-third of all the work completed on the project has been conducted by Indigenous people.

Additionally, $620 million in contract work has been awarded to Indigenous businesses for the project’s right-of-way clearing, medical, security and camp management needs, with another estimated $400 million in additional contract and employment opportunities for Indigenous and local B.C. communities during pipeline construction.

We’ve developed a plan with two components to invest in skills development and long-term education programs to support Aboriginal and local residents and trainees, like our Pathway to Pipeline Readiness and Education Legacy Programs.

Since 2014, TC Energy’s education and training programs have opened up over 450 seats in classrooms for students in B.C. Since 2012, TC Energy has invested approximately $6.5 million in communities like yours.


At Coastal GasLink, we know that water is a highly valued resource. The protection of water is of the utmost importance to both the environment and the communities around us. Our project’s 670-kilometre right-of-way crosses several bodies of water and we approach each one with the highest environmental and safety standards to prevent adverse impacts on the environment. Prior to construction, information was collected about water bodies along the route, including environmental and technical assessments. Environmental assessments included studies of the aquatic environment – such as water flow, bank stability, the quantity and quality of fish habitat, wildlife and vegetation.

Using the information gathered, we then evaluate which crossing method is best suited to the water body’s unique conditions to ensure the crossing is completed safely, leaving the natural resources above intact and undisturbed.

Visit the Water crossings section of our Environment page to read more about how we keep water bodies safe.

Learn more about how we protect bodies of water. 

Our approach to water crossings is a multi-faceted process that involves rigorous evaluation of the best available crossing methods to ensure each water body and habitat receives the appropriate protections. Our integrated multi-disciplinary field teams, which include fisheries biologists, conduct an initial site assessment to gain an understanding of the site’s underlying conditions. The technical feasibility of potential crossing methods is then determined based on site conditions, available workspace considerations, and environmental, geotechnical and geophysical data, input from engagement, and regulatory requirements. A trench or trenchless crossing method is then chosen based on all the information gathered about the local environment and the water body’s unique conditions.

Learn more about how we protect bodies of water.

Coastal GasLink will not be producing the natural gas – our role is to ensure the safe transportation of natural gas once it is produced.

Pipelines are required to undergo exhaustive environmental studies to ensure they meet stringent guidelines. Our project is being pursued under two British Columbia statutes, the Oil and Gas Activities Act, and the Environmental Assessment Act. Additional provincial and federal permits or authorizations required to start construction activities, which have been and will be pursued in a timely manner to meet the applicable construction schedule. Applicable federal legislation that applies to this project includes the Migratory Birds Convention Act, Fisheries Act, Canadian Navigable Waters Act, Species at Risk Act, and others.

Noxious weeds, as identified by the B.C. Weed Control Act, are non-native plant species that have been introduced into a region or area of the province from an outside source. These have the potential to pose undesirable or detrimental impacts on humans, animals or ecosystems. Due to the lack of predators from their natural environment that would help control their aggressive growth tendencies, noxious weeds can be highly destructive to habitat and food production values, and difficult to control if left unchecked. Early and rapid response to localized infestations is critical to keep them contained.

As is the case with all weed control treatments, application of herbicides has both benefits and limitations. The main benefits of chemical application, depending on the method, are that it can be highly selective, with little to no off-target drift and can be used on a large variety of weed species. We understand that there are concerns regarding the use of chemical applications and only employ them when deemed necessary, in accordance to regulations and consultation.

Herbicides are not applied within 10 metres of a waterbody. Extensive consultation has been done with impacted landowners and Indigenous groups to address the potential for disturbance of any sensitive areas and appropriate adjustments to the plan have been made, based on their feedback.

  • Noxious weeds can be highly destructive to habitat and food production values, and difficult to control if left unchecked. Early and rapid response to localized infestations is critical to keep them contained.

  • There are many factors to consider when prescribing a vegetation treatment for each area such as type of vegetation, native vegetation, adjacent land use, proximity to water, land features, time of year and landowner, Indigenous and stakeholder concerns.

  • Herbicides are applied only by qualified certified applicators that are specially trained to apply herbicides safely, following stringent legislative requirements.

    • All herbicides sold and used in Canada are subject to thorough review and evaluation by Health Canada’s Pest Management Regulatory Agency to ensure herbicides pose no unacceptable risk to human health and the environment when label directions are followed.
  • Manual and mechanical control involves physically removing or damaging unwanted target vegetation.
    • Manual and mechanical controls include mowing/mulching, weed whacking and hand pulling.
    • Some methods can be applied at any time of year.
    • Manual and mechanical controls are suitable in environmentally sensitive areas.
  • Cultural Control Treatments are preventative treatments that involve planting preferred forbs and grasses to disturbed sites to establish natural plant competition where noxious weeds can gain a foothold.
    • Cultural control treatments are most appropriate in small, recently disturbed areas when appropriate planting material is available.
    • These treatments are not suitable on every site because of soil and site conditions, as well as land use.


  • Landowner concerns and comments regarding weed control measures during construction activities were incorporated into the Coastal GasLink Pre-Construction Report.

  • Further opportunity for input into the project IVMP was provided through the notice, published in newspapers along the route from March 4-27th, 2020.

Indigenous communities:

  • Early engagement provided opportunities for communities to share information and provide input into the planning of the project and vegetation management activities, and engagement on the IVMP will continue.

  • We will continue to consult with and engage Indigenous groups that are potentially affected by the Project. As a part of our commitment, we will continue to share project information with Indigenous groups throughout the construction and operation of the Project.

As outlined by the B.C. Integrated Pest Management Act, a person wishing to contribute information about a proposed treatment site, relevant to the development of the pest management plan, may send their inquiry to the Project (the applicant), as outlined in our notice. Notices were published beginning March 4, 2020 to March 27, 2020 in several newspaper outlets across the Project route.

If a proposed herbicide use under the IVMP plan has the potential to significantly impact an individual or community outside of those who have been already engaged, we will make reasonable efforts to contact and consult those individuals and incorporate their feedback into the plan.

We have completed a weed inventory along the Project route to identify areas of concern, along with species and density of weeds. Each location will be assessed on a case-by-case basis and treatment options will be identified for each location individually. Land-use of the affected area to be treated, as well as adjacent land will be considered when selecting a suitable treatment option.

General FAQs

Coastal GasLink has no plans to add another pipeline to the project’s corridor. It is a fully permitted 670 km single pipeline that will safely deliver natural gas across northern BC. Adding another pipeline would require regulatory approval, including full consultation with government, Indigenous and local communities.

A core component of Coastal GasLink's ongoing engagement to develop long-term relationships with stakeholders, landowners and Indigenous communities in whose territory the company operates includes information sharing, identification of issues and efforts to address concerns. These efforts are in part, intended to avoid grievances through a proactive approach to mitigating potential grievances.

Coastal GasLink's preferred method for addressing the concerns of stakeholders, landowners, and Indigenous is through direct and respectful discussion. Issues received or identified through ongoing engagement are systematically tracked and followed up on to promote resolution. In the event that resolution through this approach is not reached, we rely on existing regulatory and legal processes. Our goal is always to treat people fairly, using a principled approach.

On Oct. 2, 2018, TC Energy announced it would proceed with construction of the Coastal GasLink pipeline project. In conjunction with that announcement, the company noted that as part of its funding plan for this $6.6-billion project it intends to explore joint venture partners and project financing.

On Dec. 26, 2019, TC Energy announced that it entered into an agreement to sell a 65 per cent equity interest in the Coastal GasLink Pipeline Project (Coastal GasLink or the Project) to KKR and Alberta Investment Management Corporation (AIMCo) on behalf of certain AIMCo clients. TC Energy is also committed to working with the 20 First Nations that have executed agreements with Coastal GasLink to provide them with an opportunity to invest in the Project. As a result, in conjunction with this sale, the Company will provide the First Nations with an option to acquire a 10 per cent equity interest in Coastal GasLink on similar terms.

We remain fully committed to the Project and will continue to construct, deliver and operate the pipeline on behalf of the partnership. Our focus remains on the successful construction of the project.


We believe engagement is a two-way process. We encourage British Columbians to share their views and concerns with us through outlets such as this web page.

Where possible, we prefer face-to-face communication with people potentially affected by the project. Our communications and engagement program has included and will continue to include free, public community information sessions; presentations to local government councils and community groups; community engagement brochures, newsletters and information packages; and the project website.
