I wonder if the writer of this story has taken FX into account. 

If the Can$ is at $0.757 US, then $53 oil is actually $70 Canadian. 

Get oil to tidewater (Transmountain, EE and to a smaller extent KXL) and the spread between light and heavy oil thins. 

Things aren't as bad as many believe they are.  The oil companies won't talk about it because they love squeezing their suppliers.  It helps keep their costs down. 

Saudi Arabia is in the process of privatizing and selling part of their national oil company and has plenty of motive to support the price of oil.
