Uranium mining in Nova Scotia

The Canadian province of Nova Scotia has been known to hold significant uranium deposits as early as the 1950s, with the largest uranium deposit in the Maritimes located in South Mountain. Mining companies invested heavily in exploration for uranium between 1976 and 1981, before the province placed a moratorium on the practice through a cabinet policy statement. Following exploration undertaken near Windsor Forks in 2008, the province enacted a legislative ban on uranium exploration in 2009.

The provincial government under Tim Houston repealed the ban on uranium exploration in 2025, sparking public opposition. A request for proposals for uranium exploration at three sites in the province did not receive any applications.
