Ultramar

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 Eastern Canada (New Brunswick, Nova Scotia, PEI and Newfoundland). It also operates ValuMax, a cashback program for fuel purchases.
