They are Importing Brent at $110 US.....but selling oil sand oil cheap to US under $90 but buying gas at the pump $1.45 per liter....per regular fuel.....and you need 4.3 litters to have a US Imperial tank=$6.23 vs $3.50 in USA?????
Funny Canadians ????
You could always counter that with "Funny Americans" :
Spending trillions on the military and fighting wars to secure oil when Canada has all they need. Why? Because they don't trust pipelines.
I am gonna guess that Brent is more efficient to refine than bitumen.
