In 2008, De Beers began production at the Snap Lake mine in Northwest Territories, Canada; this was the first De Beers mine outside Africa and was Canada's first completely underground diamond mine. However, production was suspended when the mine was put on care and maintenance in 2015. De Beers opened the Victor mine in Ontario, Canada, the same year, a day after Snap Lake. This was followed by the opening of the company's third mine in Canada, Gahcho Kué, in September 2016.
