Note: The physical capacity of a pipeline is based on many factors such as the products being carried, direction of flow, pipeline pumping capacity, and maintenance work or other pressure restrictions. The actual physical capacity of the pipeline may, at times, be higher than the assumed operational capacity stated here.
Note: The five-year average is calculated for natural gas key points using the total throughput across all trade types and direction of flows. For bi-directional key points (both export and import) the throughput is displayed for both directions, instead of the five-year average.

Description: The above dashboard displays pipeline throughput and capacity at key point(s) along the system. Where possible, the five-year average and five-year range for throughput is shown with the current year throughput to better highlight the trends. For pipeline key points with a defined location, a map is displayed next to the graph showing the approximate key point location where pipeline throughput and capacity are recorded.

Maritimes & Northeast Pipeline (M&NP) tolls are calculated in accordance with a toll settlement that is negotiated with interested parties every 2-3 years. Tolls are adjusted annually to clear deferral account balances from the previous year. Currently, the 2022-2023 Tolls Settlement Agreement is in place.
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. The abandonment surcharge is separate from and not included in the toll settlement.

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 Commission may add conditions to regulatory instruments that each company must meet. Conditions are project-specific and are designed to protect public and the environment by reducing possible risks identified during the application process.
Condition compliance is part of the CER's oversight and enforcement action is taken when required.
Conditions can be related to a specific region, or apply to the pipeline project as a whole. The map below displays the number of in progress and closed conditions mapped to economic regions as defined by Statistics Canada.
Conditions can typically be either in-progress or closed. The CER follows up on in-progress conditions.
This status refers to conditions that continue to be monitored by the CER. This happens when:
This status refers to:
Note: Some conditions apply to multiple regions. Conditions may be double counted across regions, resulting in a higher number of conditions than the totals seen in the buttons above.
Data Source: Open Government
Description: The above map displays the number of CER conditions associated with projects approved by the Commission. The map is split into two tabs which show in-progress and closed conditions separately, mapped to an economic region. If a company has no in-progress conditions specific to an economic region, the dashboard will default to show the closed conditions by region. An additional view is available which contains the number of in-progress and closed conditions that don't have a corresponding economic region in the dataset. The map regions are shaded based on the number of conditions, with lighter coloured regions containing fewer conditions compared to darker colors. Conditions that apply to more than one region are double counted in the map, and these conditions will appear in the map region total and map region breakdown for each applicable region. The condition counts contained in the map navigation buttons represent total conditions without region double counting.
Open data can be freely used and shared by anyone for any purpose. The data for these graphs are available [CSV].

The information presented here is based on CER data (2008 to current) for incidents reported under the Onshore Pipeline Regulations and the Processing Plant Regulations. New data is added quarterly. Learn more on how incident data collection has evolved since the NEB (now the CER) was established in 1959.
Companies must report events, such as incidents, to the CER in accordance with the CER Event Reporting Guidelines. Knowing what happened, and why, helps us find ways to prevent them from happening again.
As defined in the OPR, “incident” means an occurrence that results in:
As defined in the PPR, “incident” is defined as an occurrence that results or could result in a significant adverse effect on property, the environment, or the safety of persons. For the purposes of incident reporting in the PPR, events that fall under this definition include, but are not limited to:
Companies self-report incidents and are expected to take a precautionary approach in doing so. This means that even when there is doubt as to whether an incident should be reported, the company must report it. The approach is, “When in doubt, report.” This is consistent with CER-regulated companies’ responsibility for anticipating, preventing, mitigating and managing incidents of any size or duration.
The CER reviews all reported incidents to assess whether companies have taken the appropriate corrective actions and to identify potential trends in incidents. Each incident is given a status indicating the current stage of the CER's incident review.
Operation Beyond Design Limits Includes situations, such as:
Operation beyond design limit is typically linked to an over-pressure of the product in the pipe; however, if a pipe was exposed to excessive vibration and was not designed for this, this could be considered operation beyond design limits. Operation beyond design limits does not include equipment contacting the pipe, or corrosion pits, etc.

Description: The above map displays the location of product release incidents that have occurred on the pipeline system since 2008. The map defaults to show incidents as bubbles which are coloured based on the substance released. Incidents on the map can be re-categorized based on the most recently available status of the CER's incident review, the year in which the incident was reported, and the province/territory where the incident occurred. The incident map bubble can be switched to show the estimated volume of product released, with larger map bubbles showing larger release volumes relative to other product releases on the system. The incident data can also be toggled to display a stacked bar chart of incidents over time by clicking on the incident trends button above the map. The stacked bars display the number of product release incidents by year, with bar colour segments corresponding to the various products released. Similar to the map, incidents can be re-categorized by clicking on the side buttons to view a breakdown of incidents by status, what happened, why it happened, and province/territory.
Open data can be freely used and shared by anyone for any purpose. The data for these graphs are available [CSV].

Oil and gas pipeline companies regularly conduct routine operations and maintenance (O&M) activities on CER regulated pipelines. These activities include things such as pipeline repairs, investigative and integrity digs, and many other activities while promoting safety, security, environmental protection, economic efficiency, and respect for the rights of those that may be affected.
Companies are required to adhere to Canadian Energy Regulator Act’s Onshore Pipeline Regulations and operate their facilities in a manner that is safe and protects the environment. Authorizations for pipelines typically allow companies to construct and operate a facility, and companies are not required to apply for additional approval to undertake most O&M activities. In certain circumstances, companies are required to notify the CER in advance with sufficient information to make a determination as to whether to inspect O&M activities that could result in safety consequences to landowners or the public, environmental consequences, or a negative impact on normal third-party use of the right-of-way (ROW) or adjacent property.
Operations and maintenance activities include:
Where any of the following restrictions exist, the company must apply to the Commission in accordance with the CER Act and the related regulations and may not carry out the proposed activity until approval from the Commission has been obtained. The restrictions apply where:
O&M activities do not include:
Data Source: Open Government
Description: The above bar chart displays the number of O&M activities from 2015 to current, arranged based on the starting year of the activity. Each bar is stacked based on several parameters, with the default view showing the province/territory where the O&M activity occurred. Navigation buttons to the right of the bar chart provide the option to view the number of O&M activities by province/territory, if the activity includes an integrity dig, if in-stream work is required, if there are fish present, and if there are species at risk present.
Open data can be freely used and shared by anyone for any purpose. The data for these graphs are available [CSV].

As part of the CER’s environmental protection activities, we require companies to manage and remediate contamination throughout the lifecycle of the facilities. As a first step, regulated companies are required to report contamination to the CER through the online submission of the Notification of Contamination (NOC).
After the NOC is submitted, companies must demonstrate they are actively managing the contamination according to the Remediation Process Guide. The progress and current status of remediation at the contaminated site are captured in the annual update submitted by a company each year for a contaminated site.
Third party contamination is on-site contamination that is shown to not be emanating or migrating from the company’s facilities or company-owned or leased lands or Right-of-Way. While third-party contamination is not the result of company activities, the CER still requires that this contamination is reported to the CER through the submission of the NOC.
The dashboard below contains information that is contained in the NOC's and annual updates found in REGDOCS. The CER publishes NOCs that have been submitted to the CER since August 2018, when the CER started collecting this information electronically and annual updates that have been submitted since 2021. For information on contaminated sites for which NOCs were submitted prior to August 2018, email remediation@cer-rec.gc.ca.
There are many different methods and approaches to remediate contamination. Thus, when a company submits a plan for remediation (i.e., remedial action plan) for CER review, they are required to include an options analysis to support the remedial method chosen, select appropriate remediation criteria and demonstrate engagement with potentially affected persons, among other requirements. CER analysts also review closure reports submitted by the company once the remediation is completed to ensure remediation has been completed appropriately.

Description: The above map displays the approximate location of contaminated sites that have been reported since August 2018. The map defaults to show contaminated sites as bubbles which are coloured based on the year the Notice of Contamination was submitted. Contaminated sites on the map can be re-categorized based on the province/territory, if the site is within 30 metres of a water body, and the applicable land use at the site. The contaminated sites can also be toggled to display a stacked bar chart of events over time by clicking on the contaminated sites trends button above the map. The stacked bars display the number of contaminated sites reported by year. Like the map, contaminated sites can be re-categorized by clicking on the side buttons to view a breakdown of contaminated sites by site status, activity at time of discovery, pipeline or facility, and contaminant type.
