Eastern Passage has historically been tied to the fishing industry. Its waterfront has several small wharves and piers. The construction of CFB Shearwater, a military air base, at the northern boundary of the community during World War I, and the construction of the Imperial Oil (later Esso), Texaco (later Ultramar) oil refineries, the Volvo Halifax Assembly plant and automobile import/export facility following World War II redefined the local economy. New highway connections have resulted in the majority of area residents commuting to Downtown Halifax or Dartmouth.
