I want to know the answer to the following question:
Where is a sixth upgrader being built in Alberta?
All the background I'm provided with is that "A sixth upgrader, under construction in 2015 near Redwater, Alberta, will upgrade half of its crude bitumen directly to diesel fuel, with the remainder of the output being sold as feedstock to nearby oil refineries and petrochemical plants.". Is that enough to answer the question?
Answer: yes
