What we know about the Alberta oil sands leak

The ground and water near Athabasca Chipewyan First Nation in northern Alberta has become a toxic mess. A nearby oil sands site, run by Imperial Oil, has leaked industrial waste into the hunting and fishing grounds of the Indigenous community.

But the First Nation alleges Imperial Oil and the provincial regulators tasked with keeping the companies in line, hid the seriousness of the leak. Athabasca Chipewyan First Nation is only now learning of how badly their food and water could be contaminated. Energy reporter Emma Graney talks about who knew what when and how this major oil leak is destroying any trust between the public, regulators and oil sands companies.
