HARRISON, Ontario — There’s not much left of a wood pallet manufacturer near Harriston, Ontario. About 60 firefighters from across Wellington County converged on the sawmill and wood pallet maker, JM Lumber and Pallet, around 4:30 a.m. Thursday. …High winds and cold temperatures hampered firefighters efforts to contain the blaze that is believed to have started near a wood furnace on the property. By sunlight, the main building housing the business, which was Mennonite owned and operated, had been levelled. Fire officials estimate that the fire caused approximately $2 million in damage. No one was hurt during the blaze, which isn’t considered suspicious.
