VICTORIA — British Columbia will not even consider the Enbridge Northern Gateway pipeline unless the province gets a much greater share of the economic benefits, Environment Minister Terry Lake announced Monday.

“British Columbians are fair and reasonable but they have to have confidence that a fair share of benefits would come to this province before we would consider supporting any such proposal,” Lake told reporters.

The announcement came as the B.C. government unveiled five requirements that must be in place before it will consider supporting any new heavy oil pipeline.

Those include the project needing to pass environmental review, the need for better capacity to manage land- and marine-based spills, proper engagement with first nations and the requirement for B.C. to get a larger share of the economic benefits.

The new position sparked a showdown Monday between B.C. and Alberta Premier Alison Redford, who lashed out at the demand for economic benefit sharing, saying such an agreement would undermine the “fundamental fiscal arrangements of confederation.”

The Northern Gateway pipeline is a key part of Redford’s drive to diversify markets for her province, and Alberta stands to benefit significantly from its construction.

A technical report released Monday by the B.C. government shows the Northern Gateway pipeline is expected to generate $81 billion in additional taxation revenue over 30 years for governments across Canada.

Alberta is set to get the biggest single portion of those revenues, taking in an estimated $32 billion.

British Columbia, which shoulders much of the risk on the pipeline, will be left with $6.7 billion, the estimates show.

Resource royalties are not included in this estimate, and would be collected by Alberta only.

A government official could not say what royalties Alberta is expected to get as a direct result of the pipeline.

The report said Alberta stands to gain significantly from being able to get its product into new markets.

“Prices are forecast to rise between 2016 and 2046 due to the creation of a new market for Canadian oil in Asia,” said the report. “The price lift is estimated at $107 billion, split $103 billion to Alberta and $4 billion to Saskatchewan.”

Taken as a whole, Lake said the equation simply doesn’t work for B.C.

“Given that B.C. would shoulder 100 per cent of the marine risk and a significant portion of the land-based risk, we do not feel the current approach to sharing these benefits is appropriate,” he said.

“A fair share of benefits will be the focus of negotiations should there be interest in pursuing any heavy oil pipeline in British Columbia.”

In the report, the province said B.C. will shoulder 100 per cent of the marine risk, and 58 per cent of the land environmental risk.

Alberta, it says, will shoulder only 42 per cent of the land risk and none of the marine.

Lake would not say how much he thinks British Columbia should get in economic benefits from the pipeline.

A government official added that substantive discussions about revenue and royalty collections have yet to take place with Alberta, but confirmed that royalty revenue sharing is a potential subject of discussion.
