Enbridge’s Line 3 is a 1,660km crude oil pipeline which travels from northern Alberta’s tar sands through Saskatchewan and Manitoba, and across the border through North Dakota, Minnesota, and Wisconsin. In operation since the 1960s, the Line 3 pipe has deteriorated substantially and is now operating significantly under capacity because of the aging and unstable infrastructure.
Enbridge is now proposing to replace the pipeline, while expanding its capacity to nearly double and leaving the existing, decaying pipe in the ground. If built, the new Line 3 pipeline would transport 760,000 barrels of crude oil per day through Manitoba. That’s the equivalent of 48 Olympic swimming pools full of oil, every day. At an estimated $8.2 billion, this would be the largest project in Enbridge’s history.
