The CEO of Enbridge Inc. says the Line 3 oil pipeline project is on track to start delivering "lots of free cash flow'' by late this year.

Eight people were arrested in a protest to oppose construction of Enbridge's Line 3 oil pipeline replacement in northern Minnesota, authorities said.

Enbridge began construction on its Line 3 crude oil pipeline replacement in Minnesota on Tuesday.

Minnesota regulators approved the final permit Monday for Enbridge's Line 3 crude oil pipeline replacement across northern Minnesota.

Minnesota pollution regulators properly considered the construction impacts of Enbridge's plan to replace the 542-kilometre segment of its aging Line 3 crude oil pipeline that crosses the state, a judge ruled Friday

The CEO of Enbridge Inc. says an updated environmental review released by a Minnesota state agency on Monday is a "good outcome'' but declined to speculate on when its oft-delayed Line 3 pipeline replacement project will be completed.

An updated environmental review released by a state agency in the U.S. on Monday found no serious threat to Lake Superior if crude oil ever leaked from a new pipeline to replace Enbridge's aging Line 3 across northern Minnesota.

Dozens of people rallied outside a Minnesota office of Enbridge to protest the company's proposed Line 3 oil pipeline replacement.

The court said project's environmental impact statement doesn't address the possibility of an oil spill into the Lake Superior watershed.

Besides clearing the legal challenges, Calgary-based Enbridge also needs state and federal permits, which the company hopes to secure around end of the year.
