Police are trying to determine the cause behind a fire that tore through a boat docked at the Toronto Humber Yacht Club, causing $30,000 worth of damage.

Toronto Fire Capt. Mike Strapko said the fire broke out shortly before 5 a.m. Thursday near Humber Valley Road.

The 25-foot power boat was on dry land and plugged into a volt line at the time, suggesting that the fire may have been caused by an electrical issue, said Strapko.

No one was on the boat at the time of the fire.

Strapko estimates that the boat sustained $25,000 worth of damage while a neighbouring boat received about $5,000 worth of damage caused by the extreme heat.

Seven fire trucks and 30 fire fighters responded to the fire.
