Enbridge Inc. is an energy delivery company based in Calgary, Alberta, focused on transporting and distributing crude oil, natural gas, and other liquids, with a green energy division that has seen an investment of more than $3-billion in renewables since 2002.[3] The company has more than 10,000 employees, mostly in Canada and the United States. The company was initially incorporated as Interprovincial Pipe Line (IPL) in 1949, shortly after Canada's first major oil discovery at Leduc, Alberta. The original pipeline was constructed to transport oil from western Canada to refineries in the east.[4] IPL became Enbridge Pipelines in 1998. The Enbridge name is a portmanteau from "energy" and "bridge".

Delivering Energy

Enbridge operates the

Enbridge also gathers, processes, and transports billions of cubic feet of natural gas every day, and has a growing involvement in the natural gas transmission and midstream business.

As a distributor of energy, Enbridge owns and operates Canada's largest natural gas distribution utility, Enbridge Gas Distribution, which is one of the fastest-growing such enterprises in North America.

Since 2002, Enbridge has also invested about $3-billion in renewable energy, with about 1,700 megawatts (MW) of green power capacity that can supply enough zero-emission electricity for more than 550,000 homes.

Liquids Pipelines

On any single day, Enbridge's crude oil and liquids pipeline system is the largest single conduit of oil into the United States. Enbridge exports 65 per cent of Western Canadian oil, which represents 13 per cent of daily American crude oil imports.

Enbridge's pipeline systems are located in strategically important geographical areas, with an unparalleled ability to expand and extend its energy delivery networks throughout North America. Enbridge is the leading pipeline operator in both Canada's oil sands region and the rapidly growing Bakken formation in Canada and the U.S.[5]

Enbridge is currently engaged in the largest capital program in the company's 60-year history, with $27 billion in commercially secured growth investements across Enbridge's business segments. All of these growth projects are planned to be in service by 2016, and will expand Enbridge's North American pipeline and terminal network.[7]

  • Light Oil Market Access: The $6.2-billion Light Oil Market Access initiative represents a suite of projects in Canada and the U.S. to expand access to markets for growing volumes of North Dakota and Western Canadian light oil production to premium refinery markets in Ontario, Quebec, and the U.S. Midwest. Individual projects within the initiative are targeted to be available for service at varying dates between 2014 and early 2016.[7]
  • Eastern Access: The $2.7-billion Eastern Access suite of projects establishes a path for Western Canadian and Bakken crude oil to access refineries in Eastern Canada and the midwest and eastern U.S. For example, by reversing the flow of Enbridge's existing Line 9, Ontario and Quebec refineries will have access to lower-cost Western Canadian feedstock (Ontario and Quebec currently derive 18 and 90 per cent of their crude, respectively, from higher-priced offshire sources, respectively). In-service dates for Eastern Access projects range from 2013 to 2014.[7]
  • Western Gulf Coast Access: The $6.4-billion Western Gulf Coast Access initiative will connect Canadian heavy oil supply to the vast refinery complex along the western Gulf Coast near Houston. Major components of this initiative include the Seaway Pipeline reversal and expansion, and the Flanagan South Pipeline; in-service dates range throughout 2014.[7]

Natural Gas Gathering and Transmission

Enbridge transports natural gas all over North America. In Texas, through Enbridge Energy Partners, Enbridge connects three of the top four areas for natural gas development in the U.S.; Enbridge Energy Partners transports about 15 per cent of Texas' overall natural gas production. Enbridge's Western Canadian operations include interest in the Vector and Alliance pipelines, which ultimately transport natural gas to the U.S. Midwest and Ontario.[5]

Gas Distribution

With more than two million customers, Enbridge Gas Distribution and its affiliates provide gas to industrial, commercial, and residential customers in central and eastern Ontario, southwestern Quebec, and parts of northern New York State. In addition, Enbridge owns: Enbridge Gas New Brunswick, owner of the natural gas distribution franchise in the province of New Brunswick; and a 32.1-per-cent stake in Noverco Inc., which holds a majority intererest in Gaz Metro Limited Partnership, the company that distributes natural gas in Quebec.[8]

Renewable Energy

Since 2002, Enbridge has invested approximately $3-billion in green energy — wind, solar, geothermal, waste heat recovery, and a host of other alternative energy technology projects that, together, have the capacity to generate more than 1,700 megawatts (MW) of zero-emission energy.[9]

Enbridge is the largest solar energy generator, and the second-largest wind energy generator, in Canada. Enbridge's portfolio of renewable energy projects is diversified and growing, and currently includes 12 wind farms (with 1,549 MW capacity), four solar energy operations (150 MW capacity), and a geothermal project (23 MW capacity). Together, Enbridge's renewable projects supply enough zero-emission electricity for more than 550,000 homes.

Power Transmission

Enbridge has entered the power transmission business to facilitate the import and export of power, allowing markets to have efficient and economic access to existing and new-generation sources.[10]

Enbridge's Montana-Alberta Tie-Line (MATL) is a 300-megawatt (MW), 230-kilovolt (KV) electrical transmission line allowing movement of power between Alberta and Montana. The MATL project, which was expected to be put into service during the fall of 2013, will support ongoing development of a rich wind-powered generation resource and allow much-needed energy to flow in both directions, ensuring increased availability of supplies of electricity into the U.S. Pacific Northwest and Alberta.[11]


Pipelines are still the safest and most reliable way to transport large quantities of energy products. However, to bridge the energy transportation infrastructure gap, rail transport has emerged as an intermediate step before transportation providers, including Enbridge, can construct new long-term pipeline solutions.[12]

Enbridge rail facilities are responding to producer and shipper demands for more flexible, economical transportation of high-quality crude oil from the Bakken formation, located in eastern Montana, western North Dakota, and southern Saskatchewan and Manitoba. These Enbridge rail projects boost the availability of new sources of reliable, domestic crude oil to Philadelphia and other eastern U.S. refineries, reducing reliance on imports from overseas. At the same time, safety remains Enbridge's highest priority; Enbridge is committed to safe and reliable energy transportation, and the company's rail loading operations are held to those same high standards.

Pipeline Safety

Over the past decade, Enbridge has transported nearly 13 billion barrels of crude oil with a claimed safe delivery record of 99.9993 per cent [i.e. 100,000 barrels not delivered safely]. In 2012, Enbridge invested more than $800 million in programs and initiatives to ensure the safety of its pipeline system and facilities across all parts of its business. The company doubled the number of staff dedicated to leak detection and pipeline control systems, and substantially strengthened its focus on the tools, technologies, and strategies necessary to ensure the fitness of its pipelines.

Government regulations for the approval and maintenance of pipelines are transparent and rigorous. Enbridge meets and often exceeds those regulations with a focus on safety, and a commitment to adopting state-of-the-art technology, and as a result has earned recognition as an industry leader.[13]


Enbridge's safety Control Centre, based in Edmonton, Alta., is equipped with computerized monitoring and control systems that operate 24/7 and provide continuous, real-time information. These systems include ultra-sensitive acoustic devices carried by inline inspection tools that can detect leaks as small as a pinhole.

Enbridge also adds routine inspections and aerial patrols of rights-of-way to its leak-detection monitoring system.

Prevention and Maintenance

To ensure the safety of its pipelines, Enbridge selects and tests pipe prior to and during manufacture. Enbridge uses X-ray or ultrasonic testing of all welds made to a pipeline section during construction. Enbridge uses durable coating systems and cathodic protection (the use of low-voltage electric current) to protect pipe from external corrosion. Enbridge also adds corrosion inhibitors to oil in its pipeline system to nullify the potentially corrosive effect of water.[14]

Enbridge uses custom inline inspection tools, whose diagnostic capabilities provide a level of detail similar to those of MRIs, ultrasound, and X-ray technology in the medical industry. These tools regularly travel inside Enbridge's pipelines — collecting data, evaluating pipeline condition, and ensuring pipeline safety by measuring the size, frequency, and location of even small changes to pipeline walls, inspecting the inside and outside of pipes on a millimeter-by-millimeter scale.[15]

Based on those repeated inspections, Enbridge officials monitor changes in features over time. If a visual inspection is required, Enbridge performs a prevention-based Integrity Dig,[16] which would involve excavation, cleaning, coating removal, pipe inspection, maintenance and repair if necessary, pipe recoating, and backfill.[17]

Pipeline Products

Enbridge moves close to 100 separate commodities, including more than 100 types of refined products, through its liquids pipeline system.[18] Shippers are permitted to ship crude oil blends or types that meet quality specifications set by Enbridge, and filed with the National Energy Board.[19] This includes heavy crudes, such as diluted bitumen, from Canada's oil sands.

Enbridge has been transporting crude produced from Canada's oil sands region since 1968. There is nothing new about transporting this form of crude oil, and after decades of transportation on the Enbridge system, there is no evidence that internal corrosion is caused by transporting oil from the Canadian oil sands. Enbridge has never experienced an internal corrosion failure on its mainline pipeline system.

Diluted bitumen, also known as dilbit, has been studied by numerous scientific bodies, including the highly respected and influential National Academy of Sciences,[20] and found to be non-corrosive and safe for pipelines.


For 11 consecutive years, Corporate Knights, an independent Canadian-based media company, has named Enbridge to its list of the Best 50 Corporate Citizens in Canada.[21] Corporate Knights, which publishes the world’s most widely circulated CSR magazine, has also named Enbridge to its Global 100: Most Sustainable Large Corporations in the World list for five years running (2008, 2009, 2010, 2011, 2012).[22]

Enbridge has earned a place on the Dow Jones Sustainability Index (both the North American and World editions) in 2012 and 2013.[23] Enbridge has been named to the Carbon Disclosure Project’s Global 500 Carbon Disclosure Leadership List three years in a row (2010, 2011, 2012).

Enbridge has also been placed among Canada’s Top 100 Employers, Canada’s Greenest Employers, and Alberta’s Top Employers for three consecutive years (2010, 2011, 2012).[24]

Neutral Footprint Commitment

In May 2009, during Enbridge's annual general meeting in Toronto, then-president and CEO Patrick D. Daniel announced an ambitious plan to stabilize Enbridge's environmental footprint at January 2009 levels.

Resulting from that vision is Enbridge's Neutral Footprint program. Enbridge is committed to planting a tree for every tree removed to build new facilities, conserving an acre of land for every acre of wilderness permanently impacted, and generating a kilowatt of renewable energy for every kilowatt consumed by the company's operations.[25]

As of June 30, 2013, Enbridge had planted 601,830 trees,[26] conserved 51,543 acres of natural habitat,[27] and generated 3,654 gigawatt hours (GWh) of power from renewable sources.[28]

Corporate Affairs

Enbridge's board of directors consists of president and CEO Al Monaco, chair David A. Arledge, James J. Blanchard, J. Lorne Braithwaite, J. Herb England, Charles W. Fischer, Maureen Kempston Darkes, David A. Leslie, George K. Petty, Charles E. Shultz, Dan C. Tutcher, and Cathy L. Williams. The current directors of Enbridge Inc. were elected to the board during the company's annual meeting of shareholders on May 8, 2013.[29]

Enbridge's executive management group consists of president and CEO Al Monaco, Glenn Beaumont (President, Enbridge Gas Distribution), J. Richard Bird (Executive Vice President, Chief Financial Officer & Corporate Development), Janet Holder (Executive Vice President, Western Access), Guy Jarvis (Chief Commercial Officer, Liquids Pipelines), Karen Radford (Executive Vice President, People and Partners), David T. Robottom Q.C. (Executive Vice President and Chief Legal Officer), Stephen J. Wuori (President, Liquids Pipelines and Major Projects), and Leon Zupan (Chief Operating Officer).[30]

Regulatory Bodies

In Alberta, Enbridge is regulated by the Alberta Energy Regulator which replace the Energy Resources Conservation Board. Enbridge also consults with the Alberta Environment,[notes 1] government officials and local aboriginal communities.


Spills and violations

Using data from Enbridge's own reports, the Polaris Institute calculated that 804 spills occurred on Enbridge pipelines between 1999 and 2010. These spills released approximately 161,475 barrels (25,672.5 m3) of crude oil into the environment.[31]

On July 4, 2002, an Enbridge pipeline ruptured in a marsh near the town of Cohasset, Minnesota, in Itasca County, spilling 6,000 barrels (950 m3) of crude oil. In an attempt to keep the oil from contaminating the Mississippi River, the Minnesota Department of Natural Resources set a controlled burn that lasted for one day and created a smoke plume about 1-mile (1.6 km) high and 5 miles (8.0 km) long.[32]

In 2006 there were 67 reportable spills totaling 5,663 barrels (900.3 m3) on Enbridge's energy and transportation and distribution system; in 2007 there were 65 reportable spills totaling 13,777 barrels (2,190.4 m3) [33]

On March 18, 2006, approximately 613 barrels (97.5 m3) of crude oil were released when a pump failed at Enbridge's Willmar terminal in Saskatchewan.[34] According to Enbridge, roughly half the oil was recovered.

On November 28, 2007, two workers were killed when a uncontrollable blaze started at an Enbridge terminal/tank farm in Clearbrook, Minnesota. The fire forced Enbridge to shutdown the operating pipelines in the area, temporarily halting roughly 1/5 of US imports and increasing the price by nearly $1 per barrel. The pipe had leaked two weeks ago and a temporary repair had been put in place. As workers were removing the temporary repair, oil began leaking and the fumes ignited. As of 2013, local municipal water supplies in Clearbrook would be insufficient to put out another fire should one occur.

On January 1, 2007, an Enbridge pipeline that runs from Superior, Wisconsin to near Whitewater, Wisconsin cracked open and spilled ~50,000 US gallons (190 m3) of crude oil onto farmland and into a drainage ditch.[35] The same pipeline was struck by construction crews on February 2, 2007, in Rusk County, Wisconsin, spilling ~201,000 US gallons (760 m3) of crude, of which about 87,000 gallons were recovered. Some of the oil filled a hole more than 20 feet (6.1 m) deep and contaminated the local water table.[36][37]

In April 2007, roughly 6,227 barrels (990.0 m3) of crude oil spilled into a field downstream of an Enbridge pumping station near Glenavon, Saskatchewan.[34]

In 2009, Enbridge Energy Partners, a U.S. affiliate of Enbridge Inc., agreed to pay $1.1 million to settle a lawsuit brought against the company by the state of Wisconsin for 545 environmental violations.[38] In a news release from Wisconsin's Department of Justice, Attorney General J. B. Van Hollen said "...the incidents of violation were numerous and widespread, and resulted in impacts to the streams and wetlands throughout the various watersheds".[39] The violations were incurred while building portions of the company's Southern Access pipeline, a project to transport crude from the oil sands region in Alberta to Chicago.

In January 2009 an Enbridge pipeline leaked about 4,000 barrels (640 m3) of oil southeast of Fort McMurray at the company's Cheecham Terminal tank farm. Most of the spilled oil was contained within berms but about 1% of the oil, about 40 barrels (6.4 m3), sprayed into the air and coated nearby snow and trees.[40]

On January 2, 2010, Enbridge's Line 2 ruptured near Neche, North Dakota, releasing about 3,784 barrels of crude oil, of which 2,237 barrels were recovered.[37][41]

April 2010 an Enbridge pipeline ruptured spilling more than 9.5 barrels (1.51 m3) of oil in Virden, Manitoba, which leaked into the Boghill Creek which eventually connects to the Assiniboine River.[42]

July 2010, (Main article: Kalamazoo River oil spill) a leaking pipeline spilled an estimated 843,444 US gallons (3,192.78 m3) of tar sands crude oil into Talmadge Creek leading to the Kalamazoo River in southwest Michigan on July 26, near Marshall, Michigan.[43][44] A United States Environmental Protection Agency update of the Kalamazoo River spill concluded the pipeline rupture "caused the largest inland oil spill in Midwest history" and reported the cost of the cleanup at $36.7 million (US) as of November 14, 2011.[43] The cleanup is unfinished as of March 2013.[45] PHMSA raised concerns in a Corrective Action Order (CAO) about numerous anomalies that had been detected on this pipeline by internal line inspection tools, yet Enbridge had failed to check a number of those anomalies in the field.[46] The Michigan spill affected more than 50 kilometres of waterways and wetlands and about 320 people reported symptoms from crude oil exposure.[47] The National Transportation Safety Board said at $800 million, it was the costliest onshore spill cleanup in U.S. history.[48] The NTSB found Enbridge knew of a defect in the pipeline five years before it burst.[49] In June 2013, a Kalamazoo man lodged himself into an Enbridge pipeline in Marshall, MI to protest Enbridge's lack of accountability for the 2010 spill and to encourage landowners along Enbridge's Line 6B expansion to offer increased resistance to construction in 2013.[50][51]

On September 9, 2010, a rupture on Enbridge's Line 6A pipeline near Romeoville, Illinois, released an estimate 7,500 barrels (1,190 m3) of oil into the surrounding area.[43][52]

Enbridge Pipelines (Athabasca) Inc., or Athabasca pipelines, subsidiary of Enbridge Inc., (TSX:ENB) (NYSE:ENB) reported a pipeline leak site, about 70 kilometres southeast of Fort McMurray, on June 22, 2013 of approximately 750 barrels of Light Synthetic Crude oil from Line 37 near Enbridge’s Cheecham, Alberta, terminal. Line 37, constructed in 2006, a 17-kilometre-long, 12-inch diameter pipe links the Long Lake oilsands upgrader to the Cheetham terminal and is part of Enbridge’s Athabasca system.[53] Unusually heavy rainfall in the region, that caused the 2013 Alberta floods, may have caused "ground movement on the right-of way that may have impacted the pipeline."[54] Enbridge’s Athabasca (Line 19) shares a portion of right of way with Line 37 and Enbridge's Wood Buffalo/Waupisoo (Line 75/18) which also shares a portion of right of way with Line 37, a major part of the network that serves Alberta's oilsands,[53] were closed down as a precautionary measure. Operations between Hardisty and Cheecham were restored on June 23 when Enbridge’s Athabasca pipeline (Line 19) was safely restarted.[54]

On July 1, 2013, WWMT in Michigan reported that the Michigan Department of Environmental Quality had issued a citation against Enbridge for contamination of North Ore Creek by an Enbridge pipeline maintenance activity.[55]

Recent protests and controversies

In May 2012, West Coast First Nations members and supporters protested near Enbridge's Annual Shareholder's meeting, against the proposed Northern Gateway Project.[56]

On May 31, 2012, the Vancouver Observer reported about 40 protesters outside the Canadian Oil and Gas Export Summit, protesting the proposed Enbridge Northern Gateway Project.[57]

On July 17, 2012, a group calling itself "We are the Kalamazoo" protested against Enbridge's response to the Kalamazoo spill and its plans to construct the line 6B pipeline. This protest was on the second anniversary of the Kalamazoo spill.[58]

On September 14, 2012, WLNS.COM reported clashes between Enbridge and landowners over eminent domain.[59]

In August 2012, reported that a resident of Tyrone Township (MI) went out for coffee and returned to find her land torn up by Enbrige pipeline construction. In this article, the homeowner and an Enbridge representative provided alternative views on their dispute.[60]

On November 12, 2012, the Lansing State Journal reported that the head of the Line 6B pipeline project stated that he had never seen as much organized landowner resistance before despite 30 years in the pipeline industry. They noted that this was probably because of the 2010 Kalamazoo River spill.[61]

On April 20, 2013, a group of about 30 protesters gathered at the site of the Kalamazoo River oil spill to protest against tar sands oil, fracking, and Enbridge's response to the spill. As reported by Michigan live, Kalamazoo County Commissioner Jeff Heppler, whose property was affected by the spill, was present at the protest and stated, "'All I am asking is Enbridge do what they said they said they will do and what is right and take care of everybody, including the businesses that were adversely impacted by the oil spill.'" [62]

In May 2013, Hamilton area residents protested the reversal of flow in Line 9 and temporarily closed Ontario Highway 6. [63]

On June 6, 2013, a group called Hamilton 350 sent a letter of complaint to the Hamilton (Ontario) police service (HPS) for accepting over $44,000 in donations from Enbridge. The letter questions whether police officers would be impartial during any anti-Enbridge protests, given the donation. The letter questions, "If there were a standoff between, on the one side, environmentalists and/or native people (who claim the spot at which the Grand River is crossed by this pipeline) and, on the other side, Enbridge, Inc., would officers of the HPS be able to be truly impartial?" [64]

One June 26, 2013, Hamilton Police arrested at least 18 people who occupied an Enbridge pumping station for six days to protest the expansion of Enbridge's Line 9 and intent to ship diluted bitumen through the line. [65]

On June 24, 2013, a man lodged himself in a pipeline in Marshall, Michigan (USA) to protest against Enbridge.[66]

On July 22, 2013, a group of protesters locked themselves to equipment at an Enbridge pipeline construction site in Stockbridge, Michigan. Protesters stated that they had to take matters into their own hands given that state regulators were failing the public, "We felt that there was no other option.".[67]

In August, 2013, a woman climbed a tree in Marcellus, MI in protest of Enbridge's Line 6B construction.[68]

Throughout Minnesota in 2013, activists from the Red Lake and Leech Lake reservations, members of the Indigenous Environmental Network, Sierra Club, Honor the Earth, and MN350 have been taking action against the Enbridge Alberta Clipper pipeline which runs through the North half of Minnesota. At the Red Lake reservation, the only reservation in the nation to have a pipeline illegally operating under its soil without easements, a permanent encampment has been erected over the pipeline Right-of-Way, causing Enbridge to be fined for every day the pipeline is in operation. Activists from these organizations have organized demonstrations and disrupted hearings with the Minnesota Public Utilities Commission to demand that permission to increase the flow of dilbit through the Alberta Clipper pipeline be denied. In August 2013, the PUC agreed that a contested-case hearing take place to order further assessment of the environmental impacts of the increased capacity.

A Sept. 16, 2013 Inside Climate News report by Pulitzer Prize winning journalist David Hasemeyer, describes how many Michigan landowners are concerned about the safety of new Enbridge pipeline being laid within a few feet of their homes, and the lack of regulations for how close a pipeline can be constructed to an existing home. The article quotes Richard Kuprewicz, president of an engineering consulting company and an adviser to Pipeline Hazardous Materials Administration: "Clearly the pipeline safety regulations aren't adequate in this area and the siting regulations aren't adequate," Kuprewicz said. "It's a bad combination." Homeowners are questioning Enbridge's claims of putting safety first while also placing pipelines sometimes within less than 10 feet of homes.[69]

On Sept. 16, 2013 La Porte County officers arrested a woman for staging a treesit protest against Enbridge at a Line 6B construction site. A second associated suspect was also arrested.[70]
