This building, built in the 1920's and originally located on Tank Street in the town of Petrolia, was bought by Harrison Corey in 1942, and Corey Oil Company was established. Three years later the name was changed to Corey Oil Co. Ltd. It served as a distribution centre for petroleum products. In 1970 the assets were sold to Texaco Oil Co. Ltd. Charles H. Corey took over the operation as a commissioned agent until 1990 when Imperial Oil Ltd. bought out all Texaco's operations. Esso managed the business until 1992, at which time a decision to abandon the property was made. The building was donated to Discovery, and relocated onto the site in 1994. It houses our Boom Town and geology displays.
