The naysayers in BC - principally the BC NDP and their lapdog mayors and the Green Party continually claim that BC should have control as the pipeline passes through BC.  Have they bothered to read the supreme law of the land - the Constitution?

While resource extraction is an area of provincial jurisdiction when trans-provincial and even intra-provincial  works  relating to delivery of the products then it is under federal jurisdiction.

Per s. 92 (10) of the Constitution Act, 1867 such works are specifically exempted from provincial control (and bear in mind municipalities are under provincial jurisdiction):

"Works and Undertakings connecting the Province with any other or others of the Provinces, or extending beyond the Limits of the Province(and) Such Works as, although wholly situate within the Province, are before or after their Execution declared by the Parliament of Canada to be for the general Advantage of Canada or for the Advantage of Two or more of the Provinces."
