Commons Speaker Geoff Regan temporarily suspended the House sitting Thursday after angry Conservatives erupted when Regan cut off questions from Conservative MP Pierre Poilievre.

The uproar broke out after Poilievre ignored a request from Regan to cease waving a government document on carbon taxes in the air as he argued the paper had been stripped of useful information about costs of the tax for Canadian families.

Regan accused Poilievre of using the document as a prop in the House, contrary to Commons rules.

“It’s one thing to read something and another to use something as a prop,” Regan said as the confrontation began to escalate.

Ignoring Regan’s advice to continue without waving the document around, the combative Poilievre went even further.

“When it comes to the government’s memos, I can understand why you might mistake them for props,” he said, prompting Regan to go on to questions from NDP MPs, ignoring the Conservatives for several minutes.

The snub prompted yet more Conservatives to yell, but Regan went to other questioners, sparking even further chaos.

Finally, after a one-minute suspension to calm things down, Regan went back to Poilievre, allowing his question.

“I think members know it’s not appropriate to challenge the chair or to ridicule decisions of the chair,” said Regan. “With that in mind, and assuming it will not happen in the future, I go to the honorable member for Carleton.”

Liberal MP Kevin Lamoureux, the parliamentary secretary for Government House Leader Bardish Chagger, said Poilievre went too far.

“Whoever the Speaker is, whatever political entity that he or she might be of, it’s always an institution that you respect,” Lamoureux said.

“Speakers are only human. I don’t like the fact that so much disrespect for the Chamber was demonstrated,” said the veteran politician.
