That interesting. Alberta gets zero benefits when a BC company ships product east and we get all the risk of those trucks killing Albertans which happens almost every year btw. 

In 60 years, about 5000 barrels of oil has been spilled by Trans Mountain pipeline and half of that was caused road construction crew.Only 5000 barrels out of who knows how many hundreds of millions of barrels shipped. 

The number of oil tanker spills has fallen from 24 spills per year on average in the 70s to less than 2 per year in the 2000s despite a significant increase in shipping over that time..

Sounds very safe to me but you wouldn't know it listening to environmentalists who have distorted the conversion with hyperbole and outright lies.
