Economy Maritime commerce, including supplying goods to the camps for the labourers who worked on the first canal, ship repair and the provisioning trade, was, and still is, an important part of Port Colborne's economy. Like other cities in the region, Port Colborne was a heavily industrial city throughout most of the early 20th century. A grain elevator, two modern flour mills, a Vale nickel refinery, a cement plant operated by Port Colborne Canada Cement, and a blast furnace operated by Algoma Steel were all major employers. As recently as 2017, Port Colborne has been successful attracting new industry, such as the agro-business operations of Casco Inc. and Jungbunzlauer, which process corn into products such as sweeteners and citric acid. The International Nickel Company (now Vale) has long been one of the city's main employers, since the opening of a refinery in 1918. Taking advantage of inexpensive hydroelectricity from generating stations at nearby Niagara Falls, the refinery produced electro-refined nickel for the war effort, and grew to employ over 2,000 workers by the 1950s. Cutbacks in operations and increasing factory automation have reduced the workforce to its present-day (2018) total of 170.
