[1] In 2005, Kenton Joel Carnegie, a 22-year-old Canadian geological engineering student from Ontario on a work term from the University of Waterloo, was killed by wolves at Points North Landing, near Cameco's Rabbit Lake mine.

[14] On 29 August 2016, a 26-year-old shift worker walking between buildings at the Cigar Lake mine on his midnight break was attacked and mauled by a lone timber wolf.

A nearby security guard frightened the wolf away, administered first aid, and called for an air ambulance which medevaced him 675 km (419 mi) to a hospital in Saskatoon where he recovered.

After the attack, authorities ordered that area wolves be shot, that food disposal systems and fencing be inspected, and that staff be educated.
