The uber right-wing billionaire Koch brothers, owners of the U.S.'s largest private company, are some of the country's most influential Tea Party supporters, climate change deniers and anti-union activists.

Now Canadian oil is on the cusp of adding to their empire.

Already the largest foreign leaseholder in Alberta’s controversial oilsands, a Koch Industries subsidiary has filed an application to start development on the Dunkirk commercial scale oil project.

Koch Oil Sands Operating ULC, on behalf of Koch Canada Exploration submitted an application late last month for development to the Alberta Energy Regulator, and has also filed terms of reference for an environmental impact assessment to Alberta Environmental and Sustainable Resource Development.

The project, which is expected to produce some 60,000 barrels of oil per day, is located on the traditional territory of the Fort McKay First Nations, some 76 kilometres west of the oilsands hub of Fort McMurray.

In documents filed with the regulator, the company forecasts construction will begin in 2016, with production estimated to start in 2018.
