NEW YORK CITY -- Canada "won't take no for an answer" on the Keystone XL pipeline project, Prime Minister Stephen Harper says.
"This won't be final until this is approved," he said Thursday in New York City. "We'll keep pushing forward."
Harper made the comments during a question-and-answer session hosted by CNBC journalist Maria Bartiromo for the Canadian-American Business Council.
The New York business audience included Assistant Secretary of State Roberta Jacobson. The State Department is weighing whether to give the project the green light, though the ultimate decision rests with President Barack Obama.
Just two years ago, also while in New York, Harper told Bloomberg news agency he considered the pipeline project a "no brainer."
The first proposal by TransCanada for the $7 billion Alberta-to-Texas pipeline was shot down by the U.S. government soon after he made that comment.
