Lightning has struck a house and caused a fire in Gravenhurst.

It was just after 1:00am when Stations 1 and 2 from the Gravenhurst Fire Department responded to a fire call on Fleming Drive in the Kilworthy Drive area of south Gravenhurst.

When crews arrived it was determined there was a fire in the walls.

A nearby resident told that there wasn’t much of a storm going when a lightning strike followed by a massive thunderclap “shook the house.”

A total of one pump truck, one rescue unit and three tanker units were on hand.

The fire was deemed officially knocked down around 4:30am this morning.

There were no injuries reported and there is no word yet on a damage estimate.
