Mark Carney arrived on the first day of the new mission to the Prime Minister’s Office, immediately facing the question of many Canadians: When did he talk to Donald Trump?

“We’ll see it,” Carney told reporters with a smile, before flipping the stairs to his Ottawa office. In fact, Canada’s newly elected leader has not wasted time. Carney and the U.S. president spoke on the phone late Tuesday and agreed to meet in person “in the near future.”

Starting a new conversation with Trump is by far the most pressing task of the Carney administration.

The former central banker won the election after Canadians’ grudges over U.S. tariffs and Trump’s threat to his sovereignty. He told voters that decades of trade and security relations with the United States have "end".

Now, he must turn to building new relationships. A senior aide said the call with Trump was "kind" and Carney focused on the G7 summit in June (who will be held in Kananaskis in the Rocky Mountains) as a venue for face-to-face negotiations.

"We have a G7, so we can't wait," the consultant said.

Carney will have to balance voter patriotic anger as many travel to the United States and boycott American goods need to convince Trump to reach a deal.

Industry leaders were quick to urge Carney to review and extend the agreement with the United States, Mexico and Canada - the North American Free Trade Agreement, which was the president's first term.

"The business leaders in all three countries agreed that the agreement must continue as a central mechanism to manage trade and investment, resolve disputes, and improve mainland competitiveness and productivity," Goldy Hyder, head of chefs at the Canadian Business Council, said on Tuesday.

Companies and investors hope renegotiation of the deal could break the cycle of tariff threats and short-term expansion. Hyde said USMCA is the best framework for “recovering certainty, stability and predictability” for C$1.3TN ($940 billion) annual trading relationships.

Relations with the United States are still confused. With Canadians polling on Monday's election, Trump released the announcement of "Society of Truth" that Canadians should vote to be the 51st state in the United States.

State Department spokesman Tammy Bruce on Tuesday reiterated Trump's reasons for placing tariffs, a problem he beat Carney's predecessor Justin Trudeau.

"We look forward to working with Prime Minister Carney's government, especially on key issues in trade fairness, combating illegal immigration, stopping the movement of fentanyl and other dangerous drugs, and opposing the influence of the Chinese Communist Party in our hemisphere," she said.

Carney's victory speech delivered in the early morning of Tuesday outlined a plan to strengthen a "reliable partner" relationship with Europe, Asia and the rest of the world.

"If the United States no longer wants to be the forefront of Canada's global economy, we are the master's degree in our family. We will build millions of housing units. We will become an energy superpower," he said.

But despite the ambitious conversation, the economic reality is grim. Canada relies on U.S. buyers for its exports, while refineries in the Midwest rely on Canada as the largest foreign oil supplier in the United States. Transporting oil and other resources elsewhere is much more expensive.

Carney will also cut his work for him through domestic politics. The final vote confirmed on Tuesday afternoon that he won the most seats (and the right to make up the government), but second only to the parliamentary majority.

He needs to reach a deal to ensure parliamentary support, which could be with the New Democrats who support the Trudeau administration. The support of the centre-left party collapsed and its leader, Jagmeet Singh, lost his seat. But their remaining seven members are enough to push legislation through parliament.

The Conservatives performed better than expected compared to their 2021 election performance, receiving a 7.6% reward in the universal election - despite its leader Pierre Poilievre losing his seat.

Carney received only 2.4% of the vote, up 11.1% from the Liberals under Trudeau.

Carney also needs to announce a new cabinet that balances Lieutenant Trudeau such as Foreign Secretary Mélanie Joly and Trade Minister Dominic Leblanc, his rivals are leader Chrystia Freeland, and the new face.

The new leader will face demands from home industries such as carbon wood, aluminum and steel, with U.S. tariffs threatening widespread unemployment or shutdowns on businesses.

Canada's oil sector also hopes to make the most of Trump's hostilities by finding new buyers exports.

“By developing our exports to international markets, we will enhance our energy security and economic sovereignty and develop our world-class oil and gas resources into full potential,” said Lisa Baiton, CEO of the Canadian Petroleum Producers Association.

It could be a tough conversation for Carney, who has been a high-profile advocate for the “green transition.”

Despite being described as a political newbie, he only became a member of Congress on Monday, people who know Carney said he shouldn't be underestimated.

"Karni is very capable and smart and always well prepared," said the Governor of the Central Bank of India, Raghuram Rajan, who has known the leaders of the new Canadians for twenty years.
