[3][4] Its 38,300 kilometre (23,800 mile) natural gas pipeline system connects multiple Canadian provinces, several US states, and the Gulf of Mexico.

[6] To operate the United States portion of the pipeline, the Lakehead Pipe Line Company (now Enbridge Energy Partners) was created.

[28] Spectra, headquartered in Houston, Texas, operated in three key areas of the natural gas industry: transmission and storage, distribution, and gathering and processing.

Phillips 66 is one of the largest petroleum services companies in the US, owning and operating 39 natural gas plants and 51,000 miles of gathering pipe.

[58] Headquartered in Denver, Colorado, DCP operates a portfolio of natural gas gathering, logistics, marketing and processing services across nine states.

[62] Enbridge has a growing interest in European offshore wind energy, and its renewable assets are part of the company's plan to achieve net-zero emissions by 2050.

"[22] (Centre Manche 1) In February, 2020, Enbridge sold its shares of Montana-Alberta Tie-Line (MATL) to Berkshire Hathaway Energy.

The MATL project is a 300-megawatt (MW), 230-kilovolt (kV) electrical transmission line allowing movement of power between Alberta and Montana.

The MATL project, which was placed in service the fall of 2013, supports ongoing development of a rich wind-powered generation resource and allows electrical energy to flow in both directions.

[70] Additionally, in southwestern Ontario they have the largest integrated underground storage facility in Canada, and one of North America's top natural gas trading hubs.

[42] In September 2023, Enbridge agreed to acquire three natural gas utility companies from Dominion Energy for $14 billion.

[76] 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.

[78] 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.

[80] 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 U.S. gal (330 m3) were recovered.

[81][82] 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.

[79] 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.

[88] The Michigan spill affected more than 31 miles (50 km) of waterways and wetlands and about 320 people reported symptoms from crude oil exposure.

The 17-kilometre-long, 12-inch diameter pipe was constructed in 2006 and links the Long Lake oilsands upgrader to the Cheetham terminal as part of Enbridge's Athabasca system.

[96] Unusually heavy rainfall in the region, also responsible for the 2013 Alberta floods, may have caused "ground movement on the right-of way that may have impacted the pipeline.

After the incident, supply concerns reportedly helped push "oil prices 2% higher in early trading to nearly $54 a barrel.

[109] On July 22, 2013, a group of protesters locked themselves to equipment at an Enbridge pipeline construction site in Stockbridge, Michigan.

"[111] In September 2016, a group of Native Americans protested the construction of the Dakota Access Pipeline, which Enbridge had announced plans to acquire a portion of in a $2 billion deal.

[112] In November 2020, Michigan Governor Gretchen Whitmer revoked a 1953 easement for an Enbridge pipeline connecting two parts of the Great Lakes through the Straits of Mackinac.

[113] In June 2021, Enbridge resumed construction on the Line 3 replacement project in Northern Minnesota after taking a brief planned break.

[114] Enbridge's plans to expand its Line 3 pipeline in Minnesota along a new route have been met with prolonged resistance from Native communities and activists calling themselves water protectors.

[115][116] In January 2022, a group of about 400 met in front of a Bank of America location in Austin to protest Enbridge's plans to expand the Moda Ingleside Energy Center onto historic Karankawa land in Corpus Christi, Texas.

[117][118] In September, 2023, in a trial flawed by numerous protocol breaches on the part of the prosecution and local authorities,[119] Mylene Vialard was found guilty of felony obstruction.

The film documented Enbridge's trespassing on the Bad River reservation with Line 5 and the local community's struggle to get the pipeline removed.

[122] The labs use industrial predictive algorithms, machine learning, and sentiment analysis to find efficiencies within the company and help improve safety and reliability of their pipeline infrastructure.

[123] The labs have developed ways to get sensor data from pipelines, helping to improve flows of natural gas and crude oil terminals.
