EWL Management Limited is one of seven companies in Canada who manage decommissioned uranium mines[2][3] and it holds 2% of all uranium tailings in Canada.

The company is a subsidiary of Ovintiv.

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 owns five decommissioned mines in Ontario:[9][10]

The company manage 4,600,000 tonnes of uranium tailings at former mines, representing 2% of all uranium tailings in Canada.[16]

Operations

Since two of EWL's mines contaminated local groundwater,[17][18][19][20] EWL have been rehabilitating mines to meet provincial water safety standards.[11][12][19] This includes rehabilitating two tailing management areas at Madawaska Mine.[21][22] The rehabilitation is 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]
