A German multipurpose heavylifter carrying a load of scrap spent eight hours grounded on rocks in the St Lawrence Seaway on Friday before being freed by tugs.
The BBC Maple Lea ran aground near St. Nicholas Island in Châteauguay, an off-island suburb of Montreal. By Friday afternoon, after being freed, the ship was in dock near Sainte-Catherine.
The cause of the grounding was not known as of Friday night but Transportation Safety Board of Canada teams were investigating.
There was a report that the ship leaked a small amount of hydraulic oil. Absorbent booms were laid.
Owned by German firm Auerbach Schifffahrt and chartered by BBC Chartering, also of Germany, the vessel was destined for Ghent in Belgium when it landed on the rocks.
