Language Sudbury is a bilingual city with a large francophone population, with 40% of Sudburians able to speak French. Some 80.1% of the population speak mostly English at home, followed by French at 16.3%, which is significantly higher than the Ontario average of 2.4%. Economy After a brief period as a lumber camp, Sudbury's economy was dominated by the mining industry for much of the 20th century. By the 1970s, Inco employed a quarter of the local workforce. However, in 2006, Inco and Falconbridge were taken over by foreign multinational corporations: Inco was acquired by the Brazilian company Vale, and Falconbridge was purchased by the Swiss company Xstrata which was in turn purchased by Anglo–Swiss Glencore forming Glencore Xstrata. Several other mining companies, including First Nickel and KGHM, also have mining operations in the Sudbury area. Mining now employs only 6,000 people in the city, although the mining supply and service sector employs a further 10,000. By 2006, 80% of Greater Sudbury's labour force was employed in services with 20% remaining in manufacturing. Over 345 mining supply and service companies are located in Sudbury. This includes a number of public and private firms pursuing research and development in new mining technologies such as Mining Innovation Rehabilitation and Applied Research Corporation (MIRARCO), the Northern Center for Advanced Technology (NORCAT), and the Centre for Excellence in Mining Innovation (CEMI). While mining has decreased in relative importance, Sudbury's economy has diversified to establish itself as a major centre of finance, business, tourism, health care, education, government, and science and technology research. Many of these reflect Sudbury's position as a regional service center for Northeastern Ontario, a market of 550,000 people.

In the 2000s and early 2010s, projects aimed at revitalizing the downtown core included the creation of Market Square, a farmer's and craft market; the redevelopment of the Rainbow Center Mall; streetscape beautification projects; the conversion of several underutilized historic properties into mixed-use office and loft developments; and the establishment and launch of the McEwen
