[BIGSTORY.AP.ORG] Canada's government on Tuesday approved a controversial pipeline proposal that would bring oil to the Pacific Coast for shipment to Asia, a major step in the country's efforts to diversify its oil exports if it can overcome fierce opposition from environmental and aboriginal groups.Approval for Enbridge's Northern Gateway project was expected as Canada needs infrastructure in place to export its growing oil sands production. The project's importance has only grown since the U.S. delayed a decision on TransCanada's Keystone XL pipeline that would take oil from Alberta to the U.S. Gulf Coast.
The northern Alberta region has the world's third largest oil reserves, with 170 billion barrels of proven reserves.
Enbridge's pipeline would transport 525,000 barrels of oil a day from Alberta's oil sands to the Pacific to deliver oil to Asia, mainly energy-hungry China. About 220 large oil tankers a year would visit the Pacific coast town of Kitimat and opponents fear pipeline leaks and a potential tanker spill on the pristine Pacific coast.
