Canadian refinery spills diesel into St. Clair River

An unknown amount of petrochemicals spilled into the St. Clair River from a refinery in Canada during heavy rainfall Wednesday night. An overflow in Suncor’s Sarnia refinery’s internal sewer system left a sheen on the river that caused officials on both sides of the international border to close off drinking water intakes. But Canadian authorities cleared water plants to return to normal activity Thursday morning.
