CALGARY, Alberta (Reuters) – Canada on Monday formally invoked a 1977 treaty with the United States to request negotiations over Enbridge Inc’s Line 5 oil pipeline, which the state of Michigan has ordered to shut down over concerns it could leak into the Great Lakes.
Gordon Giffin, legal counsel for the Canadian government, filed a letter to the federal court dealing with the legal dispute between Enbridge and Michigan, informing the judge of the move.
Canada’s foreign ministry did not immediately respond to a request for comment.
