Conservative Leader Pierre Poilievre is accusing the prime minister of keeping Canadians in the dark on his plan to negotiate a new trade deal with the U.S., saying he needs to stop with the “showboating” and focus on “fighting the tariffs.”

Speaking to reporters in West Block on Tuesday, Poilievre dismissed Mark Carney’s video on Sunday outlining Canada’s road ahead as empty posturing and called on him to explain to Canadians how he was going to deliver a win for the country in upcoming trade talks.

“A serious prime minister would be able to tell you his plan. I’ve told you my plan. Nobody knows Mark Carney’s plan. Probably not even him. … he was elected on the single promise that he would negotiate a win with the U.S. And since that time he’s been losing, losing, losing.”

Carney released a video Sunday morning in which he pledged to “never sugar-coat” the challenges Canada faces in its relationship with U.S., and argued that connection has become a source of “weakness.”

Then on Tuesday, Carney retooled an advisory committee on Canada-U.S. trade, adding a former Conservative leader and the former high commissioner to the United Kingdom to the team.

Poilievre dismissed the moves as theatrics, and said Carney has failed to keep his campaign promise to secure a trade deal with the U.S.

He urged Carney to outline his plans for talks with the U.S. in light of the Americans suggesting that Canada hasn’t engaged in negotiations since the fall.

“At the end of the day, what you need is to have a prime minister who’s focused not on illusions and showboating, but on actually fighting the tariffs.”

Poilievre said Canada should head into the trade talks by pushing to create a strategic mineral and oil reserve to pressure the U.S. to maintain tariff-free market access.

“That is the leverage we have, and frankly, something that Prime Minister Carney should have been doing a year ago is making that point, he said.

“But in fact, he has squandered our leverage. All the leverage he had going in, he squandered by backing down on everything while getting nothing in return.”

Poilievre criticized Carney for not yet approving a new oil pipeline, for failing to end government policies he said stifle energy investment, and for not speeding up mining project approvals.

Carney’s revamped committee has more top-level business executives than the previous version.

The new group includes presidents and CEOs of major Canadian energy, resource, forestry and transportation companies. They include the heads of CN Rail, the Bank of Montreal, Nutrien, TC Energy, Canfor and Teck Resources, among others.

The list covers major Canadian industries exposed to U.S. tariffs.

Neither Carney or Canada-U.S. Trade Minister Dominic LeBlanc provided much detail about what prompted the change in membership before cabinet on Tuesday, and both ignored follow-up questions on the status of trade talks.

“It’s a diverse group — leaders in the union movement, experts in industry, CEOs in finance and across the economy,” Carney said in a brief statement as he arrived on Parliament Hill.

Canada is preparing to begin major talks this summer with the Americans and Mexicans on reviewing the continental free trade pact.

But in recent weeks, White House officials have ramped up criticism of Ottawa’s approach to trade negotiations, saying Canada is lagging behind Mexico in starting talks with the U.S.

U.S. Commerce Secretary Howard Lutnick said Friday it would be a bad strategy for Canada to try to wait out the U.S. to reach a better deal later on, adding, “They suck.”

LeBlanc said on Tuesday that he spoke with Lutnick “at length” last week and the commerce secretary made no such comments to him in private.

Asked by reporters about Lutnick’s comments, Poilievre said it “sounds like more bluster.”

Despite criticism from the White House, Peter Hoekstra, the U.S. ambassador to Canada, told iPolitics on Friday that he was confident a deal would be reached.

“I’m confident we’re going to get to a deal, it’s just taken longer and it’s been more painful than what I thought it would be,” Hoekstra said in the roughly 45-minute interview, released in its entirety on Tuesday as a special episode of iPolitics‘ No Talking Points podcast.

“It may not be an optimal deal,” he said.
