A pipeline leak in Sarnia, Ont., has been located more than a week after a sheen reportedly turned up on the St. Clair River.
Sun-Canadian Pipe Line says it pinpointed the leak on Saturday morning, nine days after the company said it was made aware of it on March 12.
Suncor, which operates a Sarnia refinery, told local media it had located a “hydrocarbon sheen” on the St. Clair River on March 11 and it had been contained.
