Alberta regulator greenlights Coalspur's Vista mine expansion amid environmental pushback

The Alberta Energy Regulator granted Coalspur Mines the necessary permits to expand the Vista Coal Mine near Hinton, turning Canada’s largest coal mine into the biggest in North America. Issued on July 20, 2026, the approval allows the open-pit to extend westward over more than 630 hectares of the Rocky Mountain Foothills adjacent to Jasper one outlet Park, raising annual production to 15 million clean tonnes and extending the mine’s lifespan by roughly 12 years.

Regulators concluded a public hearing was unnecessary, despite formal objections from conservation groups like the Canadian Parks and Wilderness Society Northern Alberta Chapter and the Alberta Wilderness Association, which warn of headwater stream damage, selenium and arsenic contamination, and threats to endangered Athabasca rainbow trout and bull trout. Provincial Energy Minister Brian Jean defended the decision as supporting jobs and energy security, while the federal Impact Assessment Agency previously determined the project did not meet the threshold for a federal review.

Permit conditions include water-release limits, a 100-metre habitat buffer, and a requirement to create an end-pit lake within ten years after mining ends. Critics argue the mitigations merely reduce, not prevent, environmental harm.
