A ship stuck in the St. Lawrence Seaway in Montreal on Thursday has been freed after blocking the busy passage for several hours.

Tugboats dislodged the ship around 2 p.m. ET and are towing it eastward.

The freighter got wedged in the canal perpendicular to the shore early in the morning, between the Jacques Cartier and Victoria bridges.

The length of the 138-metre-long freighter is the same as the canal's width, said Seaway Corporation spokesman Jack Meloche.

"The front of the vessel is actually on the north shore and the end of the vessel is actually on the south shore," said Meloche.

The freighter is carrying mechanical parts.

According to Meloche, there was no leakage as the ship ran aground.

At least five vessels were delayed because of the blocked ship.
