TransCanada said Friday it may file a new application after the United States rejected its proposal to build a pipeline connecting Canada's oil sands to US Gulf Coast refineries.

"TransCanada and its shippers remain absolutely committed to building this important energy infrastructure project," company chief executive Russ Girling said in a statement. 

"We will review our options to potentially file a new application for border-crossing authority to ship our customer's crude oil, and will now analyze the stated rationale for the denial."
