Billionaire Koch brothers are big oil players in Alberta

. . . For more than 40 years, Canada has been a wellhead of Koch’s burgeoning fortune in oil, refineries, pipelines, petroleum products and financial trading as well as an expanding list of diverse interests — producing an estimated $115 billion in revenues last year, according to Forbes.

In Canada, Koch presides over an interlocking empire of interests, from the Alberta oil sands to fibre and fuel-additive producer INVISTA in Ontario and building products distributor Georgia-Pacific in Quebec. It employs, by its own account, 2,000 people, donates to charitable causes and supports the influential pro-oil Fraser Institute.
