On Wednesday, Aug. 28, the National Energy Board (NEB) became the Canada Energy Regulator (CER). For further information please visit our Implementing the Canadian Energy Regulator Act information page

Interactive Pipeline Map – FAQs

What information is shown in the map?

The map is able to display CER-regulated pipelines, and incidents reported to the CER since January 2008.

The default display of the map shows pipelines. You can choose to display the map with pipelines and/or incidents.

The default display for incidents shows those that have not been closed.

The map can be customized to show additional years of incident data. See the user guide in the Related Pages toolbox to discover all the functionality.

Why can’t I download the data for the pipeline map?

This map shows the approximate location of pipelines based on data from a third-party supplier who specializes in digital geographic information for pipelines. As this data is licensed from the supplier, the CER cannot provide free downloads.

The CER provides its incident data in an easy to download format from the “Related Pages” tool box.

What are the differences between the two incident data download files?

The Comprehensive incident download is a detailed set of information that is collected from every reportable incident. The Map Display download is a subset of the Comprehensive dataset which only contains the fields used on the Interactive Incident Map.

What do the pipeline statuses mean?

Operating: The CER has been notified that the pipeline is being used.

Approved: The pipeline has been approved and either construction has not been completed, or the line is not yet being used.

Deactivated: The pipeline has been temporarily removed from service.

Decommissioned: The pipeline or pipeline segment has permanently ceased operation; however it does not result in the discontinuance of service.

Abandoned: The pipeline is permanently removed from operation resulting in the discontinuance of service.

What do the incident statuses mean?

Initially Submitted: The company has notified the CER that an incident has occurred and provided preliminary information. An investigation is ongoing.

Submitted: The company has submitted all of the required information and the CER’s review process is on-going.

Closed: The CER’s incident review has been completed and the file is closed.

How often is the data updated?

Data on the map is updated on a quarterly basis.

Why is location data approximate?

  1. Pipeline location:

    The CER’s record of pipeline locations is mainly based on files submitted by companies called Plan, Profile, Book of Reference (PPBoR). This online map shows the approximate location of pipelines based on data from a third-party supplier specializing in digital geographic pipeline information. As this data is constantly improved and updated, additional CER-Regulated pipelines will be added and the accuracy of pipeline location improved. Accordingly, the pipeline data shown is subject to change.
  2. Incident location:

    Prior to 2015, companies could provide their incident location information in various formats. As a result, locational data may have been extrapolated from Townships with Legal Subdivisions, Nearest Populated Centre or other sources. As of January 2015, the CER released a new Event Reporting System, which requires consistent reporting of latitude and longitude for all incidents.

Why has an incident that was previously on the map changed or disappeared?

The incident data shown is subject to change over time. As investigations are completed for open incidents, or as new information becomes available, the incident record is updated and may change the incident data, including whether the incident remains reportable under the applicable regulations. Accordingly, incident data shown is subject to change.

Why am I unable to find an incident that occurred?

  1. The incident map only includes incidents reported under the Canadian Energy Regulator Onshore Pipeline Regulations that occurred on CER-regulated pipelines. Incidents reported under other legislation such as the Canada Oil and Gas Operations Act are not currently mapped.  Information relating to incidents on CER-regulated pipelines that are not on the incident map can be obtained through the CER’s Contact Us page.  For information on incidents which occurred on non-CER-regulated pipelines, please contact the applicable regulator in the province or territory where the incident took place.
  2. If more than one incident occurred within approximately 50 meters of each other, then the incident dots may overlap on the map so it appears that one or more incidents were not mapped. This can be verified by looking at the tabular data and sorting on latitude and longitude.

How close I can zoom?

This map enables you to zoom to neighborhood level.

Why is Volume Released “Not Provided” on many Gas Release Incidents?

Volumes of natural gas releases are typically not estimated as there is no accurate method of estimating the release on a per event basis. As a result of this, the Canadian Energy Regulator Onshore Pipeline Regulations require that companies report all unintended releases of natural gas regardless of volume. While the CER does not track specific volumes, emission reporting is done at the provincial level as relevant air quality legislation often requires a level of reporting for overall emissions. For additional information on those reporting requirements, please direct inquiries to the relevant provincial authorities.

Why does an incident appear outside the Province or Territory that I selected?

This rare situation can occur if the reported latitude and longitude is outside the boundaries of the reported Province or Territory. The map uses reported latitude and longitude for the placement of the locator dot, whereas the filter uses the reported Province or Territory to select which incidents to display on the map.

Why do I see dots of different colours even after applying a filter on incident type?

Each event reported by a company may result in multiple reportable incident types. An event resulting in both a fire and a serious injury is an example of an event with multiple reportable incidents. In such cases, the dot represents multiple incident types and may appear in a colour that does not match the incident type selected in the map filter.

What is a Miscellaneous Release?

Miscellaneous releases are incidents where a product other than oil or gas is released. This includes incidents where a commodity is released from an CER-regulated pipeline, or where any other product is released from facilities, equipment or activities related to CER-regulated pipelines.

Who determines why an incident happened or what happened?

The CER requires companies to identify causes for incidents relating to their facilities, and to include these in their reports. As part of the incident review, CER staff considers whether the company has provided appropriate causes and supporting rationale.

Why do some incidents not have information for why an incident happened or what happened?

When an incident report is initially submitted, the company may not include why an incident happened or precisely what happened. This is often because the company is still investigating the incident to determine all causes. Prior to closing an incident, CER staff ensure that immediate and basic causes have been identified.

What do the release types mean?

The release type relates to the primary product that is transported in the pipeline. Examples of the release types applicable to each category are as follows:

The gas category includes substances such as natural gas, sweet gas, fuel gas, and acid gas.

The liquid category includes substances such as low vapour pressure hydrocarbons, crude oil, natural gas liquids, and jet fuel.

The miscellaneous category includes substances such as mechanical pulp slurry, steam, effluent, processed water, and fresh water.
