Saint John still maintains industrial infrastructure in the city's east side such as a large oil refinery. Wealthy industrialist K.C. Irving and his family built an industrial conglomerate in the city during the 20th century with interests in oil, forestry, shipbuilding, media and transportation. Irving companies remain dominant employers in the region with North America's first deepwater oil terminal, a pulp mill, a newsprint mill and a tissue paper plant.
Other important economic activity in the city is generated by the Port of Saint John, the Moosehead Brewery (established in 1867, is Canada's only nationally distributed independent brewery in Canada [M. Nicholson]), James Ready Brewing Co., the New Brunswick Power Corporation which operates three electrical generating stations in the region including the Point Leprous Nuclear Generating Station, Valiant Telecom which operates out of the former New Brunswick Telephone headquarters, the Horizon Health Network, which operates 5 hospitals in the Saint John area, and numerous information technology companies. There are also a number of call centres which were established in the 1990s under provincial government incentives
