Ports are federal jurisdiction so BC and Vancouver don't get the port fees.  And every ship using the port creates the same "spin off" economic benefits while most don't create the same risk (however small that may be) for major oil spills.  I can see how BCers could regard this as getting the short end of the stick.

Maybe it would help if Notley could give BC a nice contract for a big chunk of site C hydro power to replace coal, but I'm not sure if she could given Alberta's unusual deregulated and privatized system.
