The Financial Post reports in its Saturday edition that Canada's biggest pipeline export system is full and will remain so even if owner Enbridge succeeds in completing its Line 3 project, currently awaiting approval in Minnesota. The Post's Geoffrey Morgan writes that Enbridge boss Al Monaco said Friday that the company's mainline system delivered a record amount of crude from Alberta to refineries in the U.S. Midwest in December and the system would be full for at least the next three years. He said: "In December the combination of growing (Western Canadian) supply and strong refinery demand drove record deliveries of 2,733,000 million barrels per day, which is close to maximum capacity. January and February volumes look pretty strong as well and we expect the system will essentially be full for the rest of the year. In fact, we expect that to be the case through 2020, including our Line 3 given growing supply and lack of other pipeline capacity." Line 3 is a replacement project for an existing pipeline route and would double the capacity. Enbridge expects regulators expects a decision from Minnesota in the second quarter and expects the line will be shipping oil between Alberta and Wisconsin in 2019.
