The Edmonton refinery has been optimized for processing oil sands crude feedstocks. At the Sarnia refinery, a $1 billion investment in new equipment has enabled the production of lower sulphur diesel fuel and improved operational efficiency. At the Commerce City refinery, a $540 million (US $445 million) upgrade has enabled the refinery to meet clean fuels regulations and handle a wider range of oil sands products.
