If BC refuses to allow (more) oil transported through its province (even though they don't have the legal right, and the Federal government is the higher level of government last time I looked), then it could get very messy between BC and Alberta. A lot of our stuff comes and goes through Alberta and if BC is being obstructionist, then so can Alberta.

Trudeau had better stick to his guns on this, as he appears to be doing so far, or the country can fall apart with inter-provincial blockades all over the place. If BC thinks it can have its (read Lower Mainland's) way without any serious trade consequences, it is wrong.

Right now, I just expect a lot of noise and bluster from Curly and Moe, to appear to be doing something to appease their nimbyist base, but noise is all it is. Kinder Morgan has proceeded too far on this project, and won't back down - they will win in the end, and Canada needs them to.
