The cause of a massive fire early this morning on Highway 9 is being investigated today.

Jim Wall with the King City Fire Department says a massive fire started just after midnight July 20, 2013 in Schomberg in two large barns. New Tecumseth fire fighters joined in the fight against the fire. Three stations with about 50 fire fighters fought the blaze.

The cause is still undetermined and is under investigation. Wall estimates damage could exceed $400,000.
