Lakeshore fire crews were busy Sunday putting out a blaze that completely gutted a house on Puce Road.

The blaze started around 11 a.m., thankfully nobody was home at the time.

An off-duty firefighter, who lives nearby, heard "a big bang."

He notified emergency crews after seeing black smoke in the air.

OPP had Puce Road blocked off for a few hours.

A damage estimate and cause remain unknown at this point.

The Ontario Fire Marshal has been called in to investigate.
