Within seconds, Justin Trudeau’s crude outburst to Peter Kent in the Commons yesterday was perfectly captured by a Twitter writer: “shiddle-diddle.”

After Conservative Environment Minister Peter Kent scolded an NDP critic for failing to attend the climate change conference in Durban, Liberal MP Justin Trudeau says he lost it.

Outraged because Kent had refused to allow Opposition critics to travel as part of Canada’s delegation, Trudeau hollered across the aisle: “Oh, you piece of shit!”

An uproar ensued on the government benches.

There was no denial from the heir to Pierre Elliot Trudeau’s foul-mouthed mantle.

A seemingly contrite Trudeau stood after Question Period to unequivocally apologize.

“I lost my temper and used language that was most decidedly unparliamentary and for that I unreservedly apologize.”

Kent demanded a fuller apology to the House. Commons Speaker Andrew Scheer said it was enough.

Outside the Commons, Liberals and NDP vented “frustrations” and pointed fingers at the government.

New Democrat Megan Leslie ‘ whom Kent had originally targeted ‘ defended Trudeau.

“I think it was an honest reaction. He apologized for it. I just wish that the Conservatives would actually talk about issues and stop with the name calling and these kinds of dirty tricks. It’s really shameful.”
