Canadian company TC Energy needs the permit to continue building the long-disputed pipeline from Canada across U.S. rivers and streams.

Alberta Premier Jason Kenney says he believes United States presidential hopeful Joe Biden can be swayed to supporting the Keystone XL pipeline.

Jason Kenney disputed Biden's claims that the pipeline is neither economically viable nor environmentally responsible.

Billions of dollars in lawsuits will likely result if Joe Biden is elected U.S. president this November and carries out a threat to cancel the Keystone XL pipeline permit, Canadian observers say.

Prime Minister Justin Trudeau says he will press any government on the development of the Keystone XL pipeline, following Joe Biden's comments that he would "rip up" project approvals upon election.

Joe Biden's campaign says the former vice-president will rip up President Donald Trump's approvals for the Keystone XL pipeline if he takes over the White House next year.

Construction work on the Keystone XL pipeline is continuing apace despite a U.S. court ruling last month that invalidated a nationwide permit allowing pipelines to cross waterways.

U.S. District Judge Brian Morris did not immediately rule following an almost four-hour hearing that also included arguments over whether President Donald’s Trump’s authorization of the border crossing was legal.

Pipeline sponsor TC Energy will need the permit for future construction across hundreds of rivers and streams along Keystone’s 1,930-kilometer route.

TC Energy Corp. says it is fine-tuning its plan for construction, while also guarding against the spread of COVID-19.
