"Canada Invokes 1977 Treaty With US As Dispute Over Pipeline Intensifies"

"Michigan governor Gretchen Whitmer says Line 5 of pipeline is a ‘ticking time bomb’ and has ordered it shut down".

"The Canadian government has invoked a decades-old treaty with the United States in its latest bid to save a pipeline that critics warn could be environmentally catastrophic if it were to fail.

For nearly 67 years, Calgary-based Enbridge has moved oil and natural gas from western Canada through Michigan and the Great Lakes to refineries in the province of Ontario.

But Michigan’s governor, Gretchen Whitmer, says that one section of the company’s pipeline – Line 5, which crosses the Great Lakes beneath the environmentally sensitive Straits of Mackinac – is a “ticking time bomb” and has ordered it shut down."
