Line 5 — a 68-year-old, deteriorating pipeline — carries 87 million liters of oil and gas per day through the heart of the Great Lakes.

The pipeline, operated by Enbridge Energy, sits at the bottom of the Straits of Macknic between Lake Michigan and Lake Huron. According to a University of Michigan study, Line 5 lies in the worst place for an oil spill to occur. A rupture in the pipeline could contaminate up to 1200 km of Great Lakes shoreline in the U.S. and Canada.

The Great Lakes are a source of drinking water for over 30 million people in the US and Canada. They contain 21 per cent of the world’s surface freshwater and 84 per cent of North America’s freshwater. For the Anishinaabeg, the Haudenosaunee, and many Tribal Nations, First Nations, and Métis peoples, the Great Lakes are extremely important waterbodies. Line 5 threatens the waters, lands, and way of life for Indigenous peoples of the area and of all peoples living in nearby shoreline communities.

We are urging the Canadian government to:

  • Put the health and long-lasting preservation of the Great Lakes ahead of the short-term financial interests of the fossil fuel corporation, Enbridge Energy.
  • Respect the Tribes and First Nations exercising their sovereign rights as the original stewards of the land, by calling for the shut down of Line 5.
  • Prioritize the need for us to wind down the oil and gas sector in light of the urgency to act swiftly on climate change and a heating planet.

Take action today and tell the federal government to support the closure of Enbridge’s Line 5 pipeline and protect the Great Lakes.
