EDMONTON, Alberta, May 23 (UPI) -- Municipal authorities in Alberta said they were permitting a phased re-entry for some energy company employees as the wildfire threat evolves.
Around 1 million barrels per day worth of Canadian oil production was impacted by wildfires raging through parts of Alberta, home to the country's oil sands operations, since early May. The provincial government said fires remain out of control, with more than 1,900 square miles burned.
