The fire that destroyed a Canadian boathouse belonging to George Duke and Jeff Duke has been ruled arson.

A Quebec man has been charged with arson after allegedly torching a boathouse on Grenadier Island in the St. Lawrence River that belonged to George Duke and Jeff Duke.

Grenadier Island is in the St. Lawrence in Canada. The blaze, which occurred early Saturday morning and was visible from the United States, was allegedly set by Brent Bercovitch, 35, from Kirkland, Quebec.

A boathouse and several antique boats were destroyed in the fire, with Canadian officials estimating damages around $1 million.

Firefighters from Alexandria Bay in New York were called out to help firefighters from Leeds and Thousand Island Fire in Canada, according to news reports from the region.

The Watertown Daily Times reported that Ontario property records listed the Dukes as owners of the boathouse, which also included living quarters.

Reports indicate that Bercovitch had stolen a boat to get to Grenadier Island.

David VanBrocklin, chief of the Alexandria Bay Fire Department, told the Watertown Times that the boathouse was a total loss. Firefighters battled the fire from their fireboats and on land, VanBrocklin said, adding that flames were towering over nearby pine trees when the firefighters arrived.

Neither of the Dukes were able to be reached for comment on Thursday.
