Alberta Premier Alison Redford says she’s optimistic her deal with B.C. Premier Christy Clark will increase the flow of oil west to the Pacific to diversify Canadian energy markets. She spoke Tuesday to the Vancouver Board of Trade after the two premiers unveiled what they called a framework agreement for cooperation on new heavy oil pipelines. “It makes it clear, officially, that Alberta’s royalties are off the table,” Redford said. “The economic benefit cannot be provided or guaranteed by the government of Alberta.” While B.C. won’t ask Alberta to hand over any share of oil royalties or taxes, it can seek to impose its own toll or tax on oil that may flow through a new pipeline, with Alberta’s support.
