WATCH: Poilievre says Trudeau is letting US use him ‘as a doormat’

While addressing Minister of Natural Resources Seamus O'Regan during the May 10 Question Period, Poilievre listed a number of failures on the Trudeau government's part. This time, specifically on Line 5, a pipeline that is at risk of being shutdown by Michigan Governor Gretchen Whitmer.

"It is no surprise that the minister and the Prime Minister cannot get the governor on the phone themselves, because, of course, they have done nothing but fail in Canada-US relations for the last five years," he said.

"They failed to get a buy America exemption, as Harper did under Obama. They failed to resolve the softwood lumber dispute, as Harper did under George W. Bush. They have had three presidents to work with, and yet no concessions whatsoever," Poilievre continued.

"The US President will not even intervene right now to help save this vital energy link on which thousands of jobs and our entire energy system in central Canada depend."

O'Regan responded by saying that discussions with the US continue on a diplomatic level, and that the Liberals were standing up for Line 5. O'Regan also said that the Conservatives were fear mongering, saying "[the Conservatives] have been fundraising off threats to shut down Line 5."
