Description
The Many Islands pipeline system consists of 12 pipelines. These pipelines cross the Alberta/Saskatchewan border, the Manitoba/Saskatchewan border, and the Saskatchewan/United States border.
Overview
The pipelines started operating between 1966 and 2000.
In Saskatchewan, the Many Islands pipeline system interconnects with the pipeline facilities of TransGas Limited.
Many Islands Pipe Lines (Canada) Limited and TransGas Limited are wholly-owned subsidiaries of SaskEnergy Incorporated, a Saskatchewan provincial Crown corporation. The TransGas pipelines are regulated provincially by the Saskatchewan Ministry of Energy and Resources.
Supply and Markets
While natural gas is produced in Saskatchewan, the demand for natural gas currently exceeds production in the province. Pipelines are needed to import natural gas from other jurisdictions.
The Steelman-North Portal pipeline historically exported Saskatchewan gas to the U.S., although only small amounts have been exported in recent years.
Many Islands Pipe Lines (Canada) Limited has filed applications with the CER for bi-directional flow of the Steelman-North Portal pipeline due to declining gas production in Saskatchewan. [Folder 3781921][Folder 4284000]
The Swan River pipeline transports natural gas from Saskatchewan to Manitoba for delivery into the Swan Valley area. This gas can come from storage caverns in Saskatchewan.
Recent Projects
The Pierceland Supply project added approximately 31 kilometres of natural gas pipeline between Alberta and Saskatchewan, a new compressor station, and associated facilities. The project was completed in 2021.
This project will increase supply to northwest Saskatchewan to meet growing customer demand and declining natural gas production in Saskatchewan.
Project application, approvals, monitoring, and compliance information is available here: [Folder 3781663].
The Shaunavon Interconnect project connected the Many Islands pipeline system to the Foothills pipeline system.
This project involved the construction of approximately 2 km of new pipeline and a new meter station near Shaunavon, Saskatchewan. It was completed in 2020.
It was constructed to increase natural gas supply in southwest Saskatchewan to meet growing customer demand.
Project application, monitoring, and compliance information is available here: [Folder 3908917].
In 2022, the CER approved the abandonment of a segment of the Esther-Smiley pipeline. As a lifecycle regulator, the CER still has oversight over this segment of the pipeline [Folder 4096648].
Also in 2022, Many Islands Pipe Lines (Canada) Limited transferred ownership of the remaining segment of the Esther-Smiley pipeline to TransGas Limited. This segment left the CER’s jurisdiction and is now regulated by the province of Saskatchewan [Folder 4096465]
Reconciliation Content
We recognize that all lands are the traditional and/or treaty territories of Indigenous Peoples, however, in this data set, only treaty lands are represented due to data availability.
For more information about how the traditional territories of Indigenous Peoples in a region are defined, it is best to consult First Nation and Metis governments directly.
The Many Islands pipeline system consists of 12 pipelines crossing the Alberta/Saskatchewan border, the Manitoba/Saskatchewan border and the Saskatchewan/United States border.
The Many Islands pipeline segments interconnect with the pipeline facilities of the provincially regulated TransGas Limited located in Saskatchewan. TransGas Limited is the local distribution company delivering natural gas to commercial, residential and industrial customers across the province of Saskatchewan. TransGas Limited is a wholly owned subsidiary of SaskEnergy Incorporated, a provincial Crown corporation governed by the SaskEnergy Act.
Natural gas is imported from Alberta into Saskatchewan via the Many Islands pipeline system. The system receives gas via interconnections with the NOVA Gas Transmission Ltd. pipeline system and the TC Canadian Mainline.
In recent years, southwest Saskatchewan has experienced growing demand for natural gas. To meet this demand new pipelines and facilities have been added to the Many Islands system, including a new interconnect to the Foothills pipeline[Folder 3909978].
Until 2011 Saskatchewan was a net-exporter of natural gas, but production in Saskatchewan has been declining and the province now requires imports to meet provincial demand [Document C21861-4]. In 2022 Many Islands Pipe Lines (Canada) Limited filed an applications with the CER for a flow reversal and bi-directional flow on the Steelman – North Portal Pipeline segment, due to declining gas production in Saskatchewan and to increase supply [Folder 4284000]. The Steelman – North Portal Pipeline historically exported Saskatchewan gas to the U.S.
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 on key paths on the pipeline since 2005.
Many Islands Pipe Lines (Canada) calculates tolls based on a cost of service model.
Many Islands Pipe Lines (Canada) Limited is subject to Group 2 financial regulation. Accordingly, the tolls are regulated by the CER on a complaint basis.
Official CER documents related to the traffic, tolls, and tariffs for the Many Islands Pipeline are available: Many Islands Pipeline tolls documents [Folder 611065].
Description: The above chart displays tolls data for the pipeline system. Only major or benchmark toll paths are shown for illustrative purposes. To see tolls for all available system paths, see the tariff filing.
The CER requires pipeline companies to set aside funds to safely cease operation of a pipeline at the end of its useful life. In 2013, MIPL estimated it would cost $94.4 million to do this for the Many Islands pipeline system. In 2018, it updated this estimate to $116.7 million. In 2024, this number was revised to $72.3 million. MIPL is exempt from the requirement to set aside funds, because MIPL is a Crown corporation ultimately owned by the province of Saskatchewan and the risk that funds will not be available to safely and effectively abandon Many Islands is low. MIPL is required to file an annual reporting form, Appendix XVI, for companies using set-aside mechanisms other than trusts, and exempt companies.
Official CER documents related to abandonment funding can be found here, sorted by year and by company: abandonment funding documents [Folder 3300366].
Pipeline companies report important financial information to the CER quarterly or annually. A solid 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 MIPL‘s annually submitted Audited Financial Statements [Folder 573236]. MIPL’s assets increased in 2015 due to additions to property, plant, and equipment using proceeds from long-term debt. As of 2020, MIPL files the Audited Financial Statements of its parent company, SaskEnergy, which are consolidated across several subsidiaries and do not provide information specific to MIPL’s operations.

Financial regulatory audits
Section updated: October 2024
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. MIPL’s last audit was completed on 29 March 2018.
Official CER documents related to MIPL’s financial regulatory audits can be found here: [Folder 3269176]].
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.
In-Progress
This status refers to conditions that continue to be monitored by the CER. This happens when:
condition filings have not yet been received by the CER; or,
filings have been received but are under review or do not yet meet requirements; or,
a project is not completed and it has conditions, which have not been met; or,
a project has a post-construction condition, but a requirement has not yet been completed; or,
some conditions may be active indefinitely or refer to the continued operation of a pipeline.
Closed
This status refers to:
condition requirements that have been satisfied, and no further submissions from the company are required; or
conditions whose filings or actions apply to a specific phase that have been fulfilled as the phase is completed (i.e. a specific filing during construction phase). Note: comments on the required actions can still be received.
Dashboard: Many Islands Pipe Lines (Canada) Limited - In Progress Conditions by Region
Some conditions are not tied to a geographic location.

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.
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.

Reported incidents
Section updated: May 2025
Reported Incidents
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.
What is an incident? (Onshore Pipeline Regulations (OPR))
As defined in the OPR, “incident” means an occurrence that results in:
the death or serious injury to a person;
a significant adverse effect on the environment;
an unintended fire or explosion;
an unintended or uncontained release of low vapour pressure (LVP) hydrocarbons in excess of 1.5 m³
an unintended or uncontrolled release of gas or high vapour pressure (HVP) hydrocarbons;
the operation of a pipeline beyond its design limits as determined under CSA Z662 or CSA Z276 or any operating limits imposed by the CER.
What is an incident? (Processing Plant Regulations (PPR))
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:
the death or serious injury to a person;
a significant adverse effect on the environment;
an unintended fire or explosion that results in or has the potential to result in damage to company, public/crown or personal property;
an unintended or uncontained release of low vapour pressure (LVP) hydrocarbons in excess of 1.5 m³
an unintended or uncontrolled release of gas, HVP hydrocarbons, hydrogen sulfide or other poisonous gas; or
the operation of a plant beyond its design limits or any limits imposed by the CER.
Incidents and the CER
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.
CER Status
Initially Submitted: The company has notified the CER that an incident has occurred and provided preliminary information. A review has been initiated.
Submitted: The company has submitted all of the required information and the CER is reviewing the incident.
Closed: The CER’s incident review has been completed and the file is closed.
The Many Islands Pipe Lines (Canada) Limited has reported a total of 6 incidents since 2008. Of those incidents, 3 have resulted in some volume of product being released, with natural gas - sweet being the most commonly released substance. The dashboard below provides some more information about these product release incidents.
Part of the CER's incident review classifies incidents based on the
circumstances that directly led to the incident (what happened), and the underlying reasons for the incident (why it happened).
On this pipeline system, the most common what happened is external interference and the most common why it happened is engineering and planning & inadequate supervision . Take a look at the incident trends section of the dashboard below for definitions and a breakdown of what and why.
The dashboard below displays only the incidents that resulted in a release of product from the pipeline, however there are other important incident types that may not appear on the dashboard. Of Many Islands Pipe Lines (Canada) Limited's reported incidents, 0 have resulted in adverse environmental effects. There have been 0 serious injuries, and 0 fatalities related to incident events. Open the dropdown below to view the definitions of these incident types.
Incident type definitions: one incident can have multiple types
Release of Substance (featured in the dashboard) - Any time a product is unintentionally released. (Releases of non-gas low pressure products in volumes of less than 1.5 m³ are exempt from reporting.)
Adverse Environmental Effects - When any chemical substance is released at a concentration or volume that has the potential to change the ambient environment in a manner that would cause harm to human life, wildlife or vegetation (e.g., glycol, potassium carbonate, methanol, methanol mix from hydrostatic testing, etc.).
Explosion - An unintended explosion
Fatality - Any death involving employees, contractors or members of the public related to the construction, operation, maintenance or abandonment of pipelines
Fire - An unintended fire
Operation Beyond Design Limits Includes situations, such as:
over-pressures - i.e., pressures that are higher than the maximum the equipment was designed to safely handle;
vibration beyond design limits;
slope movements causing movement in the pipeline beyond design limits;
pipe exposures in rivers or streams; and
introduction of an inappropriate product (e.g., sour gas in excess of CSA limits)
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.
Serious Injury (CER or Transportation Safety Board) - Any serious injury involving employees, contractors or members of the public related to the construction, operation or maintenance of pipelines.
Dashboard: Many Islands Pipe Lines (Canada) Limited - Incidents with a product release
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.

Operations and maintenance activities
Section updated: May 2025
Operations and Maintenance Activities
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.
What activities are O&M activities (eligible activities)?
Operations and maintenance activities include:
All activities necessary to safely operate an existing pipeline;
Maintenance activities, upgrades or repairs to an existing pipeline or part of a pipeline that do not increase the approved maximum operating pressure (MOP), the stress level or diameter of the pipeline; or
Physically removing an existing section of pipe up to 5 km in length, and putting a new section of pipe in its place, as long as this replacement does not increase the approved MOP, stress level or diameter of the pipeline.
What O&M Activities require CER approval (restrictions on eligible activities)?
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:
The work includes welding on an in-service pipeline by a pipeline company that has not previously performed in-service welding in accordance with the requirements of CSA Z662-15, Clause 7.17, ‘Welding on In-Service Piping’, or the equivalent clause in the most recent edition of CSA Z662; or
The work involves the construction of an aerial crossing, excluding work on company owned or leased land relating to facilities (e.g., terminal stations, processing plants, compressor/pump stations).
What kinds of activities are not O&M activities (ineligible activities)?
O&M activities do not include:
Upgrades that result in increases above previously approved and specified levels to:
the MOP,
stress levels,
the diameter of the pipeline, and/or
airborne emissions or noise levels.
"Looping" (i.e., adding pipe parallel or adjacent to, and interconnected with, an existing pipeline for the general purpose of increasing capacity);
Construction of a new pipeline; or
Deactivation (for longer than 12 months), reactivation (where a pipeline has been deactivated for more than 12 months), decommissioning, or abandonment.
The dashboard and figures presented below only include O&M activities from 2015 onwards that require notification to the CER. Consult the O&M Requirements and Guidance Notes for a list of O&M event activities that call for notification to be filed with the CER.
Since 2015, there have been a total of 20 O&M activities reported by the Many Islands Pipe Lines (Canada) Limited. When the activity involves an integrity dig, the activity may entail exposing an area of the pipeline by performing one or more integrity assessments. There have been 17 individual integrity digs as part of the reported O&M activities.
These O&M activities can occur anywhere along or near the pipeline right-of-way, including near populated areas. In the past year (2024), O&M activities have occurred most often near Shaunavon SK among others.
There have been 0 O&M activities for which new temporary or permanent land is required and is located within critical habitat for any Endangered or Threatened species listed on Schedule 1 of the federal Species at Risk Act. When this happens, the company may be required to meet additional regulatory obligations outside of the CER Act, such as the Migratory Birds Convention Act and the Species at Risk Act.
Dashboard: Many Islands Pipe Lines (Canada) Limited - O&M Activites by Year
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.
View the requirements and guidance notes (O&M Guidelines) for more information on how these events are regulated while promoting safety, security, environmental protection, economic efficiency, and respect for the rights of those that may be affected.
Contaminated sites and remediation
Section updated: May 2025
Contaminated Sites and Remediation
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.
No contaminated sites data
There are no reported contaminated sites for Many Islands Pipe Lines (Canada) Limited. If new contaminated sites are reported to the CER for this pipeline, they will appear here following the quarterly data update.
Damage prevention is where people and pipelines meet; it is the proactive process that keeps people, the environment, and pipelines safe.
The CER takes action to protect Canadians and the environment. Some of these actions include having safety requirements for activities near the pipelines that we regulate. Unauthorized activities on or around pipelines are unsafe and illegal. If pipelines are contacted or damaged, the result could be very serious.
The CER Damage Prevention Regulations (DPRs) outline the obligations of the pipeline companies to have robust damage prevention and public awareness programs that provide people living and working near pipelines the information to ensure those activities near their pipelines are done safely with respect to the pipeline. The DPRs also outline the requirements for people living and working near pipelines to communicate with pipeline companies when they are planning any construction activity (digging, building, driving on the right-of-way) and to follow the instructions that the pipeline company gives them.
Damage prevention is a shared responsibility, and we all play a part in making sure that everyone stays safe when working near a pipeline.
Pipeline companies must immediately report to the CER any activity near their pipelines that does not follow the rules and specifications set out in the DPRs. These violations are called contravention reports. The CER provides an Open Government dataset containing information on each reported contravention. Some summary statistics and a dashboard displaying this data is available below.
From 2020 to 2025, there have been a total of 4 contraventions reported for the Many Islands Pipe Lines (Canada) Limited. Of these, 0 have included a ground disturbance, and 1 have caused physical damage to the pipeline such as dent or gouge. A ground disturbance contravention happens when someone digs below 30 cm within the pipelines prescribed area without first getting consent from the pipeline company or when a locate request hasn't been made. These events can be considered as near-miss events that could have led to a more serious pipeline incident.
The CER reviews all contravention reports submitted by regulated companies, and further action may be required of the company. From 2020 to 2025, 0 contraventions have required additional action.
Description: The above map displays the location of DPR contravention reports that have been reported for the pipeline system over the past five plus years. The map defaults to show DPR contravention reports as bubbles which are coloured based on whether the pipe was damaged. DPR contravention reports on the map can be re-categorized based on whether there was a ground disturbance, the year, and who discovered the event. The DPR contravention reports data can also be toggled to display a stacked bar chart of events over time by clicking on the DPR Contravention Reports Trends button above the map. The stacked bars display the number of DPR contravention reports by year, with bar colour segments corresponding to the event type. Similar to the map, DPR contravention reports can be re-categorized by clicking on the side buttons to view a breakdown of events by whether pipe was damaged, who discovered the event, and method of discovery.
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 emergencies 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. We oversee the emergency management program of a regulated company’s project for its entire operation.
The CER requires companies to publish information on their emergency management program and their emergency procedures manuals on their websites so Canadians can access them.
