The economy of Greater Sudbury, Ontario was dominated by the mining industry for much of the city's history. In recent decades, however, the city has diversified to establish itself as an emerging centre in a variety of industries, including finance, business, tourism, health care, education, government, film and television production, and science and technology research. Many of these industries reflect the city's position as a regional service centre for Northeastern Ontario. The city's economy and politics have also been strongly influenced by a history of labour unionism.
