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]
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.
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]
EWL Management Limited owned five decommissioned mines in Ontario: [10] [11]
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]
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]
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]
