The Lakehea Pipeline, also known as the Lakehead System, is one of the largest oil pipeline systems in the world, totaling 3,100 miles (5,000 km) in length including multiple paths. 1,880 miles (3,025 km) of the system is in the United States while the rest is in Canada. On average, it delivers 1.4 million barrels (220,000 m³) of crude oil and other products each day 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.
