The Enbridge Pipeline System is an oil pipeline system which transports crude oil and dilbit from Canada to the United States. The system exceeds 5,000 kilometres (3,100 mi) in length including multiple paths. More than 3,000 kilometres (1,900 mi) of the system is in the United States while the rest is in Canada and serves the Athabasca oil sands production facilities. Main parts of the system are 2,306-kilometre-long (1,433 mi) Enbridge System (Canadian Mainline) and 3,057-kilometre-long (1,900 mi) Lakehead System (U.S. Mainline). On average, it delivers 1.4 million barrels per day (220×10^3 m3/d) of crude oil and other products to the major oil refineries in the American Midwest and the Canadian province of Ontario. The Canadian portion is owned by Enbridge, while the U.S. portion is partly owned by that company through Enbridge Energy Partners, LP, formerly known as Lakehead Pipe Line Partners and Lakehead Pipe Line Company.

The first portion of the pipeline was built over the course of 150 days in 1950 by a 1,500-man labor force. It crossed approximately 1,600 kilometres (990 mi) from Redwater, Alberta, through Saskatchewan, Manitoba, North Dakota, and Minnesota, to the Great Lakes seaport of Superior, Wisconsin. At the same time, four oil tankers were constructed to carry the crude from Superior to oil refineries in Sarnia, Ontario. Oil first entered the pipe on August 25, 1950, and the first tanker, Imperial LeDuc, was launched on November 4. Other tankers that followed were, Imperial Redwater, Imperial Woodbend, and B.A. Peerless.
