Trudeau’s victory ends the decade-long rule of Conservative Prime Minister Stephen Harper who supports Keystone XL. If approved by the Obama administration, Keystone will send oil sands from Alberta to refineries on the U.S. Gulf Coast. Trudeau supports Keystone XL, but the newly elected prime minister’s support may fold under pressure from the White House.

President Barack Obama claims environmental and global warming concerns are keeping him from approving the project — even though the Department of State concluded the pipeline won’t increase greenhouse gas emissions and will reduce oil spill risks. The State Department also noted Keystone XL will create more than 42,000 new jobs.

Despite the State Department’s findings, Obama vetoed legislation earlier this year to approve Keystone XL. Obama’s critics say he was pressured by environmentalist billionaire Tom Steyer to veto the project. Steyer spent $73 million in the 2014 election supporting Democratic candidates.
