The Globe and Mail reports in its Wednesday edition that it will be at least another year before Canadians know exactly what went wrong at Imperial Oil's Kearl oil sands facility, as the Alberta Energy Regulator overhauls how it responds when faced with emergency incidents. The Globe's Emma Graney writes that on Tuesday, AER head Laurie Pushor faced the House of Commons environment committee over the Kearl disaster for the second time. Polluted water seeped from the site in Northern Alberta into the environment for more than a year starting in May, 2022, but no local communities were told until a separate incident in February this year. A recent report from Deloitte concluded that although the regulator's staff adhered to procedures in response to the spills at Kearl, those policies were not in line with current standards and the expectations of external stakeholders, including first nations. The report recommended a host of changes, and Mr. Pushor told the committee that most of the changes will be completed over the course of 2024. That includes improving communication processes and updating the regulator's website to make it more user-friendly and less difficult to find easy-to-understand information.
