History

The General Electric Company operated a lamp factory on the site for over 60 years. The plant opened in 1948 with 50 employees and expanded throughout the 1950s and 1960s with over 500 employees at the height of its production. The office building was constructed between 1946 and 1948 and was one of the first buildings to be completed on the site. Originally housing offices and a lunchroom, the building was continually used as office space for the factory with numerous interior alterations completed over the years to accommodate minor changes in use. In 2009, the lamp plant was decommissioned due to changes in the market; this development resulted in the heritage designation of the office building in order to retain this important heritage attribute and to recognize and commemorate the history of the site.
