With a deadline looming, Canada is fighting against the closure of Line 5, a 68-year-old underwater line that carries crude oil and natural gas liquids through the Straits of Mackinac that Michigan Gov. Gretchen Whitmer wants shut down due to spill risks.
In November, Whitmer, a Democrat, (D) announced she was revoking a permit that allows Calgary, Alberta-based multinational energy provider Enbridge Inc. to operate the Michigan portion of the Line 5, a 4-mile section along the bottom of the straits between Lake Michigan and Lake Huron.
