One of the biggest Canadian oil pipelines to the United States has been shut down after a leak was discovered Sunday night, according to operator Enbridge Inc.
Line 3 connects Hardisty, Alta., with Wisconsin, carrying 450,000 barrels of oil a day to refiners in the U.S. Midwest — more than 20 per cent of Enbridge's capacity on its mainline, which is comprised of several links.
