Does Alberta Have Both The Legal Authority & The Gumption To Block Oil Shipments To BC?
In a word, yes.
1 – Does Alberta Have the Legal Authority To Block Oil Shipments to British Columbia?
As explained in the video below, ALL oil and gas products in Alberta used to be COMPLETELY controlled by the Alberta Petroleum Marketing Commission (APMC) which still exists today. There has been no legal impediments to that process put in place since the APMC was formed in 1973, so yes the Province of Alberta can legally block petroleum shipments to BC.
