Alcan Incorporated was a major Canadian aluminum mining and manufacturing corporation. From the early 1990s to the early 2000s, it was the second-largest aluminum producer in the world.The company was originally founded in 1902 as the Northern Aluminum Company Limited, located in Shawinigan, Québec. It was established as the Canadian subsidiary of the Aluminum Company of America (Alcoa), one of the founders of which invented the process for extracting aluminum from bauxite. Northern Aluminum was renamed the Aluminum Company of Canada in 1925, and in 1928, it formally detached from Alcoa. In 1966, it was again renamed, this time as Alcan Aluminum Limited (becoming Alcan Incorporated in 2001). In 2007, Alcan was purchased by the British-Australian multinational corporation Rio Tinto for $38 billion. Today, Rio Tinto continues to operate several smelters in the Saguenay–Lac-Saint-Jean region of Québec, as well as in Kitimat, British Columbia.
