St. Clair River
On 25 June 1980 "Montrealais" collided with "Algobay" in the St. Clair River in dense fog at 05:08 while transiting in opposite directions. Both ships suffered severe damaged to their bows as a result of the collision. No crewmembers were injured in the collision, but some oil was spilled into the St. Clair River. As a result, the shipping channel was closed until 07:30. "Montrealais" required over $1.5 million CAD in repairs.
