UPDATE: Residents Near Sarnia Urged to Stay Indoors Due to Fire

Correction: A previous version of the story misidentified the location of the fire. It is downriver from the St. Clair River in St. Clair County.

Fire officials are urging St. Clair County residents, especially those with breathing difficulties, to stay inside due to a fire in Ontario that's sending thick, black smoke across the St. Clair River.

A marina that houses as many as 75 boats and several antique and collectible cars caught fire this morning near Sarnia, Ontario.

"Apparently, the fiberglass that's burning is causing some toxic fumes," Lambton OPP Const. Chrystal Jones told the CBC. "We're asking people to stay clear of the area and to keep an eye on the smoke, to stay indoors and to stay out of the path of that because it could cause you respiratory or lung problems."

A fire official told WDIV-TV that the area downriver from Sarnia is in the direct path of the smoke.
