Pipeline Profiles: Maritimes & Northeast

Pipeline system and key points

Section updated June 2020

The Maritimes & Northeast Pipeline (M&NP) was commissioned in December 1999 to transport natural gas produced from the Sable Offshore Energy Project to markets in the New Brunswick, Nova Scotia, and the U.S. Northeast. Since 2007, M&NP has also been transporting supply from the McCully natural gas field in New Brunswick. Since August 2013, M&NP has been transporting offshore natural gas from the Deep Panuke project as well.

A key point on M&NP is an import/export interconnect with the US portion of M&NP at the Canada-U.S. border near St. Stephen, New Brunswick.

M&NP is bi-directional. When offshore production is insufficient to meet domestic demand, natural gas flows from M&NP U.S. into Canada. Additional supply comes from the Canaport LNG import terminal via the Brunswick Pipeline or from the Portland Natural Gas Transmission System.

Natural gas supply from offshore Nova Scotia remained below historical levels in 2017, averaging 164 MMcf/d in the first half of the year. Production at Deep Panuke has been sporadic due to water incursion into the reservoir and may end within a few years. Production at Sable has remained steady but is in long-term decline and may come to an end within a year or two.

This map provides an overview of the Maritimes & Northeast pipeline.

You can see the M&NP and all CER-regulated pipelines on the CER’s Interactive Pipeline Map. The map shows more detailed location information, the products carried by each pipeline, the operating status and more. You can also view a system map on the Maritimes & Northeast Pipeline website.

Throughput and capacity

Section updated quarterly (early March, mid-May, mid-August and mid-November)

Note: The physical capacity of a pipeline is based on many factors such as the direction of flow, ambient temperature, pipeline compression, and maintenance work or other pressure restrictions. The operational capacity at each key point may also reflect contracts for transportation service, and supply and demand across the system. The actual physical capacity of the pipeline may, at times, be higher than the assumed operational capacity stated here.

Open data can be freely used and shared by anyone for any purpose. The data for these graphs are available.


Section updated June 2020

A toll is the price charged by a pipeline company for transportation and other services. Tolls allow pipeline companies to safely operate and maintain pipelines. Tolls also provide funds for companies to recover capital (the money used to build the pipeline), pay debts, and provide a return to investors. The interactive graph below shows the tolls for key paths on the pipeline since 2006.

Open data can be freely used and shared by anyone for any purpose. The data for these graphs are available.

M&NP tolls are calculated in accordance with a toll settlement for 2020 to 2021 and are cost-based. M&NP uses a ‘postage stamp’ tolling model in which the toll is the same for all paths on the system regardless of the distance travelled.

Official CER documents related to the traffic, tolls and tariffs for M&NP can be found here: M&NP toll documents [Folder 92842].

Abandonment funding

Section updated June 2020

The CER requires all pipelines to set aside funds to safely cease operation of a pipeline at the end of its useful life. In 2016, M&NP estimated it would cost $167 million to do this. These funds will be collected over 19.5 years and are being set aside in a trust.

Pipeline financial information

Section updated June 2020

Pipeline companies report important financial information to the CER quarterly or annually. A strong financial position enables companies to maintain their pipeline systems, attract capital to build new infrastructure, and meet the market’s evolving needs. The data in this table comes from M&NP’s Quarterly Surveillance Reports [Folder 162864].

Financial regulatory audits

Section updated June 2020

The CER audits pipeline companies to confirm compliance with the Canadian Energy Regulator Act, regulations, CER orders and CER decisions. Financial regulatory audits focus on toll and tariff matters such as detecting cross-subsidies. M&NP’s last audit was completed in September 2009. Official CER documents related to M&NP’s financial regulatory audits can be found here: [Folder 571193].

Condition compliance

Section updated June 2020

Every pipeline company in Canada must meet federal, provincial or territorial, and local requirements. This includes Acts, Regulations, rules, bylaws, and zoning restrictions. Pipelines are also bound by technical, safety, and environmental standards along with company rules, protocols and management systems. In addition to these requirements, the CER may add conditions to regulatory instruments that each company must meet. Condition compliance is monitored by the CER and enforcement action is taken when required. For a detailed list of conditions that M&NP must meet, and their status, please see the condition compliance table and search for “Maritimes & Northeast Pipeline Management Ltd.”

Safety performance

Section updated June 2020

The CER holds the companies it regulates accountable to protect the safety of Canadians and the environment. As part of this accountability, companies must report to the CER events such as incidents and unauthorized third-party activities that happen without the pipeline company’s written consent. For a summary of pipeline incidents and unauthorized activities on M&NP since 2008, visit the Safety performance dashboard and select “Maritimes & Northeast Pipeline Management Ltd.”

Emergency management

Section updated June 2020

The CER checks to make sure companies are keeping pipelines safe by doing inspections, in-depth safety audits, and other activities. Yet, even with these precautions, an emergency could still happen. Sound emergency management practices improve public safety and environmental protection outcomes, and provide for more effective emergency response.

The CER holds its regulated companies responsible for anticipating, preventing, mitigating, and managing incidents of any size or duration. Each company must have an emergency management program that includes detailed emergency procedures manuals to guide its response in an emergency situation. We oversee the emergency management program of a regulated company’s projects as long as they operate.

The CER requires companies to publish information on their emergency management program and their emergency procedures manuals on their websites so Canadians can access emergency management information. To view Maritimes & Northeast’s Field Emergency Response Plan, go to its Responding to Emergencies website.
