Hear from Annette, Canadian Association of Energy & Pipeline Landowner Associations, on how landowners feel about Line 3

VIDEO -- Annette Schinborn CAEPLA CEO explains

Line 3 Replacement Program (Canada)

The $5.3-billion Canadian portion of the Line 3 Replacement Program involves the replacement of approximately 1,070 km of Line 3 pipeline between Hardisty, Alberta and Gretna, Manitoba with new pipeline.

The Canadian program also includes:

  • Installation of 55 new remotely operated valves
  • Installation of 18 new pump stations and associated infrastructure and equipment
  • Construction of three new oil storage tanks at the Hardisty Terminal in Alberta (total capacity of approximately 150,000 cubic metres), and;
  • Interconnections at facilities

Construction began in the summer of 2017 and resulted in on-time/on-budget completion of about one-third of the Canadian portion of the project, along about 418 km of the project right-of-way (ROW) in Alberta and parts of Saskatchewan. Related facilities construction at nine of 18 sites is also nearing completion.

Our plan is to start construction on the remaining Canadian pipeline replacement segments (Saskatchewan and Manitoba) in the fall of 2018. We continue to anticipate an in-service date for the project in the second half of 2019.

In the U.S., replacement of the segment of Line 3 that runs from the Minnesota border to Superior, Wisconsin, was also completed in 2017. Construction is expected to begin in Minnesota in early 2019, after the Minnesota Public Utilities Commission (MPUC) approved the Line 3 Replacement Project on June 28, 2018, granting a Certificate of Need and approving Enbridge’s preferred route with minor modifications and certain conditions.

Enbridge is committed to keeping communities informed in a timely manner as we progress through construction and our plans evolve.


As part of the L3RP, the existing Line 3 pipeline will be decommissioned—and Enbridge will be remain responsible for the decommissioned line.

A decommissioned pipeline is taken out of service safely and permanently, but left in place while other existing or new pipelines in the same right-of-way continue to provide service to end users.

The process of decommissioning a pipeline typically involves: removing the oil from the pipeline; cleaning the pipeline; physically disconnecting the pipeline; segmenting the pipeline and continuing to monitor it.

Leaving the decommissioned pipeline in place is the safest and least disruptive option— it means minimal disturbance during project construction and significantly reduces the risk of future soil and slope instability.

Pipeline Safety

Over the past decade, from 2008 through 2017, Enbridge has transported more than 22 billion barrels of crude oil, with a safe delivery record of 99.99966 per cent. We know that’s not good enough, because our goal—simply, unequivocally—will always be zero incidents.

At Enbridge, we back up our safety priorities by investing heavily in the tools, technologies, and strategies to ensure our energy transportation and distribution systems operate safely, reliably, and in an environmentally responsible manner. In 2017, we spent $1.95 billion on programs that help us to maintain the fitness of our systems, including our crude oil and liquids network, across our operations in Canada and the U.S.

Answering Your Questions

Replacing Line 3 is in the public interest because it reduces both the frequency and the magnitude of ongoing maintenance activities that would otherwise occur in order to maintain the safe operation of Line 3. This means significant benefits to landowners, local communities, and the environment.

Replacing Line 3 is also in the public interest because it would better serve the current and future petroleum requirements of the general public, who are dependent on refineries to meet their refined petroleum product needs.

Listening to you, understanding your views, and working to address your concerns are important to Enbridge. Our team is dedicated to ensuring you have informative materials and are given the opportunity to share your feedback with us. We want to hear from you.

We have hosted a variety of consultation activities. We're committed to continuing to give you the opportunity to meet and talk with team members, keep you informed with program updates, and engage our Mainline communities. Please see our Community Outreach section for information on how to contact us.

Line 3 Products

Line 3 is a “mixed-service” line, meaning it carries a variety of crude oils, including sweets, light and high sours, and light synthetics.

Shippers are permitted to ship crude oil blends or types on Enbridge’s liquids pipelines system that meet stringent quality specifications set by Enbridge, and filed with the National Energy Board. This includes heavy crudes such as diluted bitumen—which has been studied by numerous scientific bodies, including the highly respected and influential National Academy of Sciences, and found to be non-corrosive and safe for pipelines.

At Enbridge, we’ve been transporting crude oil produced from Canada’s oil sands region since 1968. There is nothing new about transporting this form of crude oil—and after nearly half a century, there is no evidence that internal corrosion is caused by transporting oil from the Canadian oil sands. In fact, Enbridge has never experienced an internal corrosion failure on its mainline pipeline system.
