— Saturday’s fire at H.J. Heinz Company’s Ontario factory caused as much as $15 million to $20 million in damage and took several hours to extinguish. Firefighters responded to the fire around 8:20 p.m. in the mixing room on the second level of the factory, Ontario Fire Chief Allan Higinbotham said. Smoke filled the entire plant, and the fire took some time to locate due to its location deep within the facility. No one was injured in the blaze.
