As I said before, 99.2% of all Canadian crude oil exported goes to the U.S. The other 0.8%  (around 25,000 b/d) that goes to other countries than the U.S. is largely light crude oil produced in the East Coast. With Enbridge and its American partners building, retrofitting and reversing the flow of existing pipelines in the U.S., the capacity to carry crude from the Alberta bitumen oil sands will be enough to carry all future production.  (Financial Post, Nov 3, 2015: "America has built the equivalent of 10 Keystone XL pipelines since 2010 - and nobody said anything").  With the recent approval of Line 3 pipeline replacement (760,000 b/d), Enbridge and other Canadian pipeline companies will be able to feed new pipeline routes bringing more Canadian heavy crude oil to U.S. Gulf Coast refineries where it can be processed (VICE News, March 12, 2015: "Line 61, the Oil Pipeline That Will Dwarf Keystone XL").  Few refineries around the world can process Alberta's bitumen heavy crude oil
