Ultramar is an Eastern Canadian gas and home fuel retailer, with head office in Montreal. It used to have oil refining and marketing operations known as Golden Eagle or Aigle d'or. It was a subsidiary of Valero Energy Corporation, an American company that acquired Ultramar's parent company, Ultramar Diamond Shamrock. Ultramar has been a trademark of CST Brands Inc. after it was spun off from Valero in May 2013. Today, Ultramar operates gas stations and home fuel delivery in Ontario, Quebec, and Atlantic Canada. It also operates ValuMax, a cashback program for fuel purchases.


Jean-Gaulin Refinery in Lévis, Quebec

The Company was formed by Ultramar plc, a British Group, who established operations in Canada in 1961.[1] Its refinery in Lévis, Quebec was built ten years later.[1]

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.[1]

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.[1]

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.[2]

In 1994, Ultramar acquired Sergaz (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.[3]

In 1997, the Sunoco name was withdrawn from Quebec, and all stations converted to the Ultramar brand.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.[1]

On December 31, 2001, Valero Energy Corporation completed its acquisition of Ultramar Diamond Shamrock.[4]

On May 1, 2013, Ultramar was spun off from Valero Energy Corporation to become a trademark of CST Brands Inc.
