The successor of multiple historical Canadian mining and energy companies, EWL Management Limited was an Alberta based corporation that owned five decommissioned mines in Ontario, including three former uranium mines.[1]
EWL Management Limited was one of seven companies in Canada who managed decommissioned uranium mines[2][3] and, as of 2016, held 2% of all uranium tailings in Canada.
The company was a subsidiary of Ovintiv, and dissolved into Ovintiv in February 2022.
Corporate history
In 1996, Conwest Exploration Company Limited was acquired by Alberta Energy Company, which became AEC West.[4] AEC became Encana with legacy mines being moved into the holding of subsidiary EWL Management.[4][5] Encanada, and EWL, became Ovintiv in 2019.[4][6]
The company was registered on 17 October 2007 in Alberta, originally as 356823 Alberta Ltd, changing its name to EWL Management Limited in 2009.[7][8]
Assets
EWL Management Limited owned five decommissioned mines in Ontario:[9][10]
- Madawaska Uranium Mine, Bancroft[11][12][13][14]
- Dyno Uranium Mine, Bancroft[11][12][14]
- Greyhawk Uranium Mine, Bancroft[15]
- Coldstream Copper Mine, Burchell Lake Area, Thunder Bay[15][4]
- Gordon Lake Mine, near Werner Lake in the Kenora District[15]
The company managed 4,600,000 tonnes of uranium tailings at former mines, which in 2016 represented 2% of all uranium tailings in Canada.[16]
Operations
Since two of EWL's mines contaminated local groundwater,[17][18][19][20] EWL were rehabilitating mines to meet provincial water safety standards.[11][12][19] This included rehabilitating two tailing management areas at Madawaska Mine.[21][22] The rehabilitation was managed by Golder Associates with the aim to make the site compliant with Canada's Nuclear Safety and Control Act and Ontario's Mining Act.[22]
Dissolution
EWL dissolved into Ovintiv in on 22 February 2022.[23][24] The Canadian Nuclear Safety Commission obliged Ovintiv to meet the licensing requirements of the two licenses WNSL-W5-3101.1/2034 and WNSL-W5-3100.0/2036.[24]
