Enbridge Brand Guidelines: Interprovincial Pipe Line 1949, the 1998 Name & Line 5

A 1949 oil line from Leduc.

Enbridge began as the Interprovincial Pipe Line Company, incorporated on 30 April 1949, two years after Canada’s first major oil discovery at Leduc, Alberta. English Wikipedia says the company was formed by Imperial Oil to carry Alberta oil to refineries; Enbridge’s own history page puts it differently, saying that “officially” it was incorporated in 1949 by the Canadian federal government, and that its businesses and legacy assets have roots going back to 1847.

The first line ran from Leduc to Regina, Saskatchewan. In 1950 it was extended through Gretna, Manitoba, to Superior, Wisconsin, and a separate company, the Lakehead Pipe Line Company, was set up to run the United States section, according to English Wikipedia. The system reached Sarnia, Ontario, in 1953 and Toronto and Buffalo, New York, in 1956; the company was listed on the Toronto and Montreal stock exchanges in 1953. A 645-mile line from Superior to Sarnia, now known as Line 5, was completed in 1953, and before it oil from Superior reached southern Ontario by tanker, English Wikipedia says.

The name changed several times before it settled. Interprovincial built the Norman Wells pipeline in the Northwest Territories in 1983, gained control of Home Oil in 1986 and renamed itself Interhome Energy in 1988, then returned to the name Interprovincial Pipe Line in 1991. In 1994, after buying the gas distributor Consumers’ Gas and moving into gas distribution, it became IPL Energy. In 1998 IPL Energy became Enbridge Inc., a name that English Wikipedia describes as a portmanteau of “energy” and “bridge.”

Oil lines, gas lines and utilities.

Enbridge is headquartered in Calgary and runs pipelines in Canada and the United States carrying crude oil, natural gas and natural gas liquids, alongside gas utilities and renewable power. English Wikipedia says the company released its first annual sustainability report in 2001 and bought its first wind farm in 2002, and in 2009 bought the Sarnia solar plant in Ontario.

The largest change came through a merger. On 6 September 2016 Enbridge agreed to combine with Spectra Energy, the Houston gas pipeline company spun off from Duke Energy in 2006, and the merger was completed on 27 February 2017, according to English Wikipedia. Spectra brought the Texas Eastern system, which carries gas from the Texas Gulf Coast to the New York area. Enbridge’s own history pages trace Texas Eastern back to its purchase of the wartime “war pipelines” after the Second World War, and describe one of those lines as helping the Allies; we give that as the company’s account.

A second expansion moved Enbridge further into gas distribution. In September 2023 it agreed to buy three gas utilities from Dominion Energy. Enbridge announced on 7 March 2024 that it had closed the purchase of The East Ohio Gas Company, which now trades as Enbridge Gas Ohio, and on 3 June 2024 that it had closed the purchase of Questar Gas and its related Wexpro companies, according to its news releases. Its Canadian distribution business, the former Consumers’ Gas, is now Enbridge Gas Inc.

The company’s record includes serious spills. On or about 25 July 2010, Line 6B ruptured near Marshall, Michigan, and oil entered Talmadge Creek and the Kalamazoo River; the U.S. Environmental Protection Agency attributed the discharge to stress corrosion cracking and to control-room errors. On 20 July 2016 the EPA and the Department of Justice announced a Clean Water Act settlement with Enbridge companies covering that spill and a September 2010 spill near Romeoville, Illinois, with civil penalties and new spill-prevention and leak-detection measures across its Great Lakes pipelines. English Wikipedia says Enbridge completed the river cleanup under the EPA’s order in 2014.

How the category presents itself.

Pipeline and midstream companies sell a service most people never see. Oil and gas move underground, through compressor and pump stations, into storage tanks and terminals, and the companies that run these systems present themselves through the places where that work becomes visible: aerial photographs of a cleared right-of-way running straight across prairie, through forest or over a river crossing, and pictures of compressor stations, tank farms and terminals at dawn or dusk.

Export is the other recurring image. Where a network ends at the coast, the reports and investor decks turn to liquefied natural gas: carriers moored at export terminals, loading arms and storage domes, often photographed from the air. Inside, the visual language changes to the control room, with rows of screens tracking flows and pressures along thousands of kilometres of pipe, a picture of supervision as much as of scale.

Much of the printed material is addressed to neighbours rather than investors. Operators produce public-awareness and landowner-relations brochures that explain where a line runs, how to call before digging and whom to contact, alongside maps, marker-post photographs and emergency numbers. These documents tend to be plain and practical, with the company name and a simple palette doing most of the identity work.

The largest set-pieces are corporate sustainability reports and investor-day presentations: maps of the whole system, charts of throughput and capital plans, photographs of crews, wildlife and landscapes, and recurring sections on Indigenous and community relations. For a designer, the register is calm, technical and heavily mapped, with photography of land and infrastructure carrying the brand more than any single symbol.

Line 5 and the Straits of Mackinac.

Line 5 has become the most closely watched part of the network. Between Michigan’s Upper and Lower Peninsulas it crosses the bottom of the Straits of Mackinac, where Lake Michigan meets Lake Huron, as two parallel 20-inch pipes. In December 2018 the state’s Mackinac Straits Corridor Authority approved a plan for Enbridge to build a tunnel in the bedrock under the Straits to hold a replacement section, according to English Wikipedia. In June 2019 the state of Michigan went to court seeking to close the Straits section, and in November 2020 Michigan’s governor revoked the 1953 easement for the pipeline’s crossing of the Straits.

The dispute has since run through several courts. In 2021, and again in 2022 over a separate case in Wisconsin, the Canadian government invoked a 1977 treaty with the United States on the uninterrupted flow of oil across the border. In Wisconsin, the Bad River Band of Lake Superior Chippewa sued Enbridge in 2019 over the line’s route across its reservation; a federal district court ruled in June 2023 that Enbridge was trespassing and ordered it to reroute or close that stretch by June 2026, and the case went on to appeal, English Wikipedia says.

For a design guide, Enbridge shows how a pipeline company built from a series of renamed predecessors can settle on one coined name and apply it to oil lines, gas systems and local utilities alike. Compare TC Energy, its Calgary neighbour, which also replaced an older name, and Pembina. For this guide we use navy, gold and a steel grey with a sans, an unofficial interpretation; no product or logo is reproduced.
