An auto repair shop south of Owen Sound saw its main building destroyed by fire Sunday night.

Crews were called to Steve Jobin & Sons Truck & Auto Centre, at the site of the former Grew Boat Manufacturing property on Sideroad 6 near Rockford, shortly before 9 p.m.

The main building of several on the property was fully engulfed when firefighters arrived.

Firefighters from seven stations were brought in to fight the flames, while Highway 6 & 10 was closed through the night and into Monday afternoon as pumper trucks were filled from a nearby stream.

Grey County OPP say the cause of the fire has yet to be determined, but the Office of the Fire Marshal has been called in.

No injuries were reported.

Anyone with information is asked to contact OPP at 1-888-310-1122 or Crime Stoppers at 1-800-222-8477.
