The Globe and Mail reports in its Tuesday edition that Alberta Premier Danielle Smith went into the first ministers meeting calling for a commitment to an oil pipeline to the Northern B.C. coast. The Globe's Campbell Clark writes that some Eastern Canadian premiers suggested they are keen on an oil pipeline that would go across the country from west to east. Neither exists yet. There is no company proposing to build either. But even as concepts, they are very different. They would serve very different purposes. One is driven primarily by economics and diversifying markets. The other is about Canada's energy security. Both are concerns kindled by U.S. President Donald Trump's trade war. Questions remain after Monday's meeting in Saskatoon between the premiers and Prime Minister Mark Carney. Mr. Carney, however, indicated he would support a pipeline that delivers "de-carbonized" barrels -- and hinted that a pipeline could go ahead if the Pathways Alliance project for carbon capture also advances. An east-west pipeline might not get built unless the government steps in to subsidize it. The only real justification for doing that would be to make sure that the oil shipped from west to east does not flow through the U.S.
