WOLFE ISLAND, ONTARIO A tugboat towing two empty barges ran aground near the east end of Wolfe Island about 6:40 a.m. Thursday.
St. Lawrence Seaway officials said no fuel leaks have been reported but approximately three gallons of hydraulic fluid from tugboat Echo IIs rudder area leaked into the river.
The tug is owned by the Quebec-based marine services company Ocean Group.
Andrew Bogora, a spokesman for the Canadian Seaway Management Corp., said nobody was injured and that the grounding off Quebec Head of the island does not pose a threat to the environment.
The grounded boat will not interrupt navigation along the shipping channel, he said.
U.S. and Canadian authorities are investigating the cause of the grounding and a salvage tug is heading to the scene of the accident.
