A fire tore through the former Pie Pizza restaurant around 8 o'clock Friday evening in Collingwood.

Multiple fire units were dispatched to the building that once housed the popular pizza spot on First Street which is now under renovation for a new tennant.

Smoke could be seen billowing from the roof. Fire crews say it was a hectic scene as they used a ladder truck to pump water onto the top of the building.

A witness said that at one point the flames were getting high and that firefighters had to break windows and were using chainsaws to get inside.

Collingwood Fire Chief tells CTV News they decided to attack the fire from the back of the building and through their aerial unit above. Fire burned through the roof creating a large hole, the Chief explained. He mentioned the blaze is now extingished and crews are going over the scene to ensure all hot spots are out.

There is no word on what caused the blaze that caused $100,000 damage. The fire was contained to the building and did not spread to the neighbouring Asian Pho restaurant.
