The Quebec government is expected to call on TransCanada to ensure its proposed Energy East pipeline complies with the province's environmental laws, Radio-Canada has learned.
Environment Minister David Heurtel has called a news conference for this morning in Montreal.
Today's announcement comes as TransCanada prepares to face hearings at Quebec's environmental review board next week.
The Quebec government made the same demands in 2014.
But TransCanada did not comply, because it said its project was subject to federal regulations, not provincial ones.
According to Quebec's environmental act, the province says it is allowed to tell TransCanada what it should include in an environmental impact study.
Mayors opposition is Criticized
The project has run into some controversial opposition in Quebec, with many municipalities arguing that environmental risks outweigh the economic rewards.
In January, mayors from the Montreal area announced their opposition to the project.
And less than two weeks ago, a coalition of Quebec environmental groups filed a court motion against the project.
The $15.7-billion Energy East pipeline would carry 1.1 million barrels a day of western crude as far east as Saint John, N.B., serving domestic refineries and international customers.
