Donald Trump has issued a presidential permit to TransCanada for the construction of the Keystone XL Pipeline, the North American energy company today announced.
"This is a significant milestone for the Keystone XL project," said Russ Girling, TransCanada's president and chief executive officer.
"We greatly appreciate President Trump's administration for reviewing and approving this important initiative and we look forward to working with them as we continue to invest in and strengthen North America's energy infrastructure," Girling added.
The multibillion-dollar pipeline is set to carry more than 800,000 barrels per day of heavy crude from Canada's oil sands in Alberta into Nebraska where it will link to an existing pipeline network and be taken to US refiners.
Trump signed an executive order to revive the Keystone and Dakota Access pipelines soon after taking office.
TransCanada will still need approval from state regulators, and the controversial pipeline could face legal challenges.
The energy firm has invested more than $15bn in liquids and natural gas projects across the US.
