Federal Natural Resources Minister Seamus O'Regan said in a recent statement "Line 5 does not just affect one province or one region — it supports our entire country." The Canadian government has filed a brief in connection with the legal dispute between Michigan and Enbridge. The Canadian and U.S. chambers of commerce have also joined forces with their counterparts in Ohio, Michigan and Wisconsin by filing a joint brief in court arguing against Whitmer's bid to shut down the cross-border pipeline. "It remains the safest, most efficient way to transport fuel to refineries and markets and is a reliable source of energy for Michigan, Ohio, Pennsylvania, Ontario and Quebec," O'Regan said, adding that close to half of Quebec’s fuel supply derives from that pipeline.
