Last month, NEB said U.S. oil imports from Canada have increased from 16 percent of total U.S. imports in 2005 to 32 per cent in 2013.

The Canadian Association of Petroleum Producers said crude oil output is expected to reach 3.9 million barrels per day in 2015, a 500,000 bpd per day increase from previous levels.
