- On July 6, 2012, the new Canadian Environmental Assessment Act, 2012 came into effect, changing the requirements for low-risk environmental assessments (EAs). As a result, the EAs underway on these projects are no longer required under the former CEA Act. However, environmental impacts and mitigation measures for the projects will continue to be considered under the Nuclear Safety and Control Act as part of the CNSC’s licence application review to ensure there is no unreasonable risk to the environment or human health and safety. It is important to note that these projects will also still be subject to other relevant federal and provincial laws, regulations and standards.

Operating uranium mines and mills in northern Saskatchewan

Northern Saskatchewan is one of the world’s leaders in uranium production. It is home to three active uranium mines and three mills, with another mine currently under construction. Additional new mining and milling projects have also been proposed for northern Saskatchewan.
At this time, all operating uranium mines in Canada are located in northern Saskatchewan, although new mining and milling projects are proposed for Quebec and Nunavut. In Saskatchewan, AREVA Resources Canada and Cameco Corporation are the two main licensees of the active mining and milling facilities.
