Wentworth Street is a Lower City arterial road in Hamilton, Ontario, Canada. It starts off at the base of the Niagara Escarpment (mountain) on Charlton Avenue East just south of the CP lines and runs right through the city's North End industrial neighbourhood and ends north of Burlington Street East at Pier 14, which one time was used by International Harvester (1902–1992).
From 1971 to 2016 it was a one-way street southbound-only from just north of Delaware Avenue to Barton Street East. It was decided to revert it back to two-way traffic in an effort to make it less of a "freeway" and more pedestrian friendly.
Wentworth Street, is named after Sir John Wentworth, lieutenant-governor of Nova Scotia, from 1792 to 1808.
The first Westinghouse manufacturing operation outside of the United States was established in Hamilton, Ontario in 1897 on Sanford Avenue, one year after The Dominion Power and Transmission Company was formed in Hamilton. This marked a new industrial era for Hamilton. It was then incorporated in 1903, (1903–1997). Company founder George Westinghouse set up a factory to build air brakes for the booming rail industry. Eventually the company was producing from its Hamilton plants electric ranges, refrigerators and washing machines. During each of the wars it was also producing guns, ammunition, anti-radar devices and bomb sights. At its peak in 1955, Westinghouse employed 11,000 people in Hamilton. (second only to Stelco) Westinghouse in Hamilton was the first company in Canada to manufacture radios (1923) and electric air cleaners (1944).
International Harvester became the second major United States industry to locate in Hamilton, Ontario in 1902, (1902–1992). Originally known as Deering Harvester, the company plant sprawled along the Hamilton waterfront and claimed to be the "largest agricultural implement works in the British Empire." The plant was also involved in wartime production of specialized military items. The company started building heavy duty diesel trucks in Hamilton in 1959. The first to roll off the line was delivered to Dofasco, complete with a Rolls-Royce engine. Hamilton won over a number of Canadian cities when it successfully lured International Harvester. The reasons the company cited for its selection of Hamilton were as follows: it had waterside property that enabled the firm to control its own docks, its proximity to the steel industry, railway connections & the Cataract Power Company supplied them with cheap energy.
