On December 6, 1979, a seemingly ordinary shopping day at Metropolitan's downtown Ottawa store became a toxic-air emergency when 21 employees were overcome by fumes and sent to hospital. An investigation discovered that three small doors on a furnace air unit had been propped open, allowing carbon monoxide and other poisonous gases to enter the main sales area. Tests by Ottawa Gas Company confirmed that carbon monoxide caused the victims' symptoms, while accumulated carbon deposits in the furnace and chimney worsened the danger. The store was temporarily closed while a work crew cleaned the furnace and repaired the chimney, reopening later that evening at 6:00 p.m. The incident exposed how routine maintenance failures in a busy retail building could put workers at risk in the very space where customers were expected to shop, eat, and browse clothing and household goods.
