Prime Minister Mark Carney addressed reporters on Tuesday, hours after his Liberal party swept byelections in Ontario and Quebec, giving them enough seats for a majority in the House of Commons.

Unsurprisingly, Carney was asked what was on the agenda now that the Liberals don’t need to rely on support from the other parties.

He pointed to affordability measures — such as the temporary pause on fuel taxes he had just unveiled — as well as standing up Build Canada Homes and accelerating major projects.

Now none of these initiatives are opposed by the Conservatives, who even proposed a longer pause on fuel taxes.

When asked specifically what he could advance that he wasn’t able to do previously with a minority government, Carney cited delays in passing legislation and dysfunction at parliamentary committees, where the Liberals can be outvoted by the combined weight of the Bloc Quebecois and Conservatives.

“We’ve had a variety of issues over the course of the Parliament where things have taken longer than they necessarily would, where debates have been more performative than actual debates around substance. I don’t want to read into the record, although other deputies in Parliament did read into the record, their love of cats and dogs. But these are examples. These are real examples in committee,” he said.

Carney then went further and said that with a Liberal majority, there would be less theatrics at committee.

“There’s a difference between real testimony, real substance, getting to issues, debating aspects of law, advancing —that’s the job of parliamentarians — and showboating. We’re going to have less of that. We’re going to have more substance. I think all parliamentarians in the end, we’ll appreciate that, even if it’s a change for some of them,” he said.

“It’s time to get serious and we’re going to be serious.”

Why does this matter?

Well, now that the Liberals have a majority, they can reconfigure the composition of committees, and give themselves a majority of seats there too.

One Liberal source told iPolitics the PM needed to go on the record explaining his rationale for the decision.

The source was granted anonymity to discuss the issue candidly.
