Say goodbye to dirt cheap Canadian oil For years U.S. drivers have been getting a gift at the expense of their northern neighbor—artificially cheap oil. That could change in the coming months when a major pipeline expansion will allow Canadian oil more access to global markets. That will change in the coming months when Canada opens up its expanded Trans Mountain pipeline, adding 590,000 barrels-a-day of takeaway capacity. Startup is expected in the second quarter, according to a spokesperson for the project. The expanded capacity is expected to start up gradually, which should prevent sudden price surges, according to John Auers, managing director of refined fuel analytics at RBN Energy.
