Actually the majority of Metro Vancouver gas comes from WA State's 3 refineries. The crude they use is bought from Alberta and pipelined to the refineries. Once there the WA State takes what they need. What Vancouver gets is speculated on, refined and sent North at market up.

Would be great if Alberta would look after refining for Vancouver's needs but they don't care do they. Nor do they care that the crude going to Houston then overseas is refined in Houston before its shipped. Yet in Vancouver, the crude is not refined and sent through some of the most beautiful and marine resource rich coastlines that could have transited areas destroyed with one crude spill of bitumen.
