A global centre for mining technology and research, Sudbury is the site of the world's largest mineral exploration and mining-service clusters in the world.It is home to two of the world's deepest mines and is the corporate headquarter for numerous multinational mining companies. Ravaged for decades by industrial pollution, it has since been recognized by the United Nations for its widely celebrated remediation and rehabilitation success story, now referenced as the Sudbury Protocol.<br><br>The world now turns to Sudbury for environmental solutions. Laurentian's proximity to the mining operations of Vale, Glencore, Kidd Creek, Hemlo, Red Lake, Goldcorp, Placer Dome, and mines in northwestern Quebec, as well as E.B. Eddy's large scale wood processing facilities at Espanola, make it a natural laboratory for the study of environmental impact, management and ecological recovery issues.
