Ultramar is an Eastern Canadian gas and home fuel retailer, with head office in Montreal. It was also a Canadian oil refining and marketing company formerly known as ''Golden Eagle'' or ''Aigle d'or''. It was a subsidiary of Valero Energy Corporation, an American company that acquired Ultramar's former parent company, Ultramar Diamond Shamrock. Since May 2013, Ultramar has been a trademark of CST Brands Inc. after it was spun off from Valero. Today, Ultramar operates gas stations and home fuel delivery in Ontario, Quebec, and Eastern Canada (New Brunswick, Nova Scotia, PEI and Newfoundland). It also operates ValuMax, a cashback program for fuel purchases. ==History== The Company was formed by Ultramar plc, a British Group, who established operations in Canada in 1961.〔(Ultramar: Our history )〕 Its refinery in Lévis, Quebec was built ten years later.〔 From 1979 to 1996, Ultramar grew by acquiring stations from several other companies, including Canadian Fuel Marketers, Texaco Canada, Gulf Canada, Sergaz, Sunoco and Spur.〔 In 1981, Ultramar acquired Hanford, California-based Beacon Oil Company. It retained the name. In 1990, it acquired the Dartmouth, Nova Scotia refinery with the purchase of other assets of Texaco Canada.〔 In 1991, Lasmo, a British oil company, bought Ultramar plc and in 1992 LASMO spun off the North American refining and marketing operations which became known as ''Ultramar Corporation''.〔(Scripophily )〕 In 1994, Ultramar acquired Sergaz (originally founded in 1971 by André Ducharme) and Sunoco's Quebec gas stations. Some gas stations still operate under Sergaz but most were closed. In 1996, Ultramar Corporation merged with Diamond Shamrock to form ''Ultramar Diamond Shamrock''. In 1997, the Sunoco name was withdrawn from Quebec, and all stations converted to the Ultramar brand. The refinery in Lévis was renamed in honour of retired Ultramar Diamond Shamrock CEO Jean Gaulin in 2001.〔 On December 31, 2001, Valero Energy Corporation completed its acquisition of Ultramar Diamond Shamrock.〔(Valero plans to buy Ultramar ) Los Angeles Times, 8 May 2001〕 On May 1, 2013, Ultramar was spun off from Valero Energy Corporation to become a trademark of CST Brands inc. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Ultramar」の詳細全文を読む スポンサード リンク
