A planned Trans- Canada Corp. oil pipeline designed to ship crude from Western Canada to Eastern Canadian refineries could also be used to access the Gulf Coast, creating an end-run around U.S. permitting delays for the Keystone XL pipeline, according to the company’s chief executive. TransCanada ’s proposed 1.1 million-barrel-a-day Energy East pipeline has been positioned in Canada as a nation-building project to connect Alberta’s landlocked oil sands with refineries in Quebec and coastal New Brunswick. But Chief Executive Russ Girling said it would also open up a new route to ship heavy crude by tanker to refineries on the Gulf Coast without requiring U.S. approval, unlike the more direct Keystone XL route from Alberta to Texas.
