Cities including Hamilton, Oshawa, Oakville, Whitby and Kitchener all contain major large-scale industrial production facilities, Hamilton being dominated by the steel industry and Oakville and Oshawa primarily in the automotive industry. Other significant automotive-production facilities also exist in Brampton, and St. Catharines. While manufacturing remains important to the economy of the region, the manufacturing sector has experienced a significant decline since 2000 as a result of unfavourable currency exchange rates, increasing energy costs, and reduced demand from the United States, which is by far the largest market for Ontario's goods.
