Mining uncovers Ontario's full potential by powering regional development, creating opportunities and driving prosperity.
Mining is an industry which is active in all parts of the province. Diverse communities such as Windsor, Goderich, Perth, Midland, Sudbury, Timmins, Red Lake, Kirkland Lake, Marathon and North Bay all have mining as an important contributor to their local economies. In some parts of the province, especially in the Far North, mineral resource development is critical to creating employment and entrepreneurial spin-off opportunities.

As the largest private sector employer of Indigenous Canadians, mining makes a significant contribution to the well-being and development of remote communities. In major urban centres like Toronto, the industry provides a major boost to the supply, services and financial sector. The Toronto Stock Exchange (TSX) is the leading global mining exchange, listing more of the world's public mining companies and raising more mining equity capital than any other exchange.
In addition to 36 mines, there are currently 21 mills for metal mines in Ontario. The province also has five refineries and three smelters (note that Cameco's Uranium Conversion facility is in the same classification as smelters) for metal mines.
