The company was one of seven companies in Canada which 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]
The company was registered on October 17, 2007 in Alberta, originally as 356823 Alberta Ltd, changing its name to EWL Management Limited in 2009.[6][7]
Encanada, and EWL, became part of Ovintiv in 2019,[4][8] and is now known as Ovintiv Canada ULC.[9]
Assets
EWL Management Limited owned five decommissioned mines in Ontario:[10][11]
- Madawaska Uranium Mine, Bancroft,[12][13][14][15]
- Dyno Uranium Mine, Bancroft,[12][13][15]
- Greyhawk Uranium Mine, Bancroft,[16]
- Coldstream Copper Mine, Burchell Lake Area, Thunder Bay,[16][4] and
- Gordon Lake Mine, near Werner Lake in the Kenora District.[16]
The company managed 4,600,000 tonnes of uranium tailings at former mines, which in 2016 represented 2% of all uranium tailings in Canada.[17]
Operations
Since two of EWL's mines contaminated local groundwater,[18][19][20][21] EWL were rehabilitating mines to meet provincial water safety standards.[12][13][20] This included rehabilitating two tailing management areas at Madawaska Mine.[22][23] 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.[23]
Dissolution
EWL dissolved into Ovintiv in on February 22, 2022.[9][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]
