Mark Carney has been elected leader of Canada?s Liberal Party in a months-long, high stakes race to replace Justin Trudeau.

He will now be expected to lead the party into the next federal elections ? which must be held before October, but could be called much earlier ? where he is likely to face stiff competition from the Conservative party, which is currently leading in the polls.

While Carney will take over immediately as Liberal Party leader, Trudeau will remain as Canada?s prime minister for an as-yet undisclosed transitional period while his successor settles in.

One of the biggest issues in Carney?s immediate inbox will be the country?s souring relations with the United States.

US President Donald Trump has repeatedly blamed Canada for illegal immigration into the US, threatened to turn Canada into a 51st state, and impose steep tariffs on Canadian imports, which the White House says is necessary to stem the flow of fentanyl over its borders.

In his first remarks following the result of the vote, Carney referenced the tensions with the US, saying his government would ?create new trading relationships with reliable trading partners.? He also vowed to keep retaliatory tariffs on the US ?until the Americans show us respect.?

?New threats demand new ideas and a new plan,? he told the Liberal Party convention on Sunday.

Slamming the Trump administration?s tariff plans, Carney said of the US president, ?He?s attacking Canadian families, workers, and businesses and we cannot let him succeed and we won?t.?

?In trade as in hockey, Canada will win,? he added.

The ripple effects of the tense relations with the US have spread through Canadian society, with fans at NHL and NBA games in Canada even booing the US national anthem.

Carney will now face off with Conservative leader Pierre Poilievre, who has previously been compared to Trump but now seeks to distance himself from the US leader, reiterating at a press conference earlier this week that he is ?not MAGA.?

At a rally on Sunday ahead of the Liberal vote, Poilievre delivered scathing remarks about Carney, a former governor of both the Bank of England and Bank of Canada, portraying him as a leader ill-equipped to deal with Trump.

?Working for Trudeau, Carney made Canada weaker and poorer; working for himself Carney made the United States richer and stronger,? Poilievre said.

In his remarks following the results of the vote, Carney shot back at his conservative opponent.

?Donald Trump thinks he can weaken us with his plan to divide and conquer. Pierre Poilievre?s plan will leave us divided and ready to be conquered,? Carney said.

In recent weeks, the lead enjoyed by the Conservatives has narrowed as Trudeau, Carney and other Liberal Party figures have taken strong positions on the trade dispute with the US.

Trudeau has led the party for over a decade. He took the Liberals to power in 2015, promising ?sunny ways? for Canada and was elected two more times, most recently in 2021, when he remained in power but lost his governing majority.

Trudeau?s impending departure follows a series of political crises, rising economic discontent and the surprise resignation of his deputy prime minister and finance minister Chrystia Freeland ? who was also in the race to succeed him.

In some of his last remarks as Liberal Party leader, Trudeau warned Sunday that Canadians face an ?existential challenge? from the US.

?This is a nation-defining moment,? he told the Liberal leadership convention in Ottawa, ahead of Carney being announced as his successor.

?And now, as Canadians face from our neighbor an existential challenge, an economic crisis, Canadians are showing exactly what we are made of,? Trudeau said.

Carney started his career in finance and in 2019 he was appointed UN Special Envoy for Climate Action and Finance. Drawing on his background, Carney has made clean energy, climate policies and economic prosperity for Canada some of the central facets of his campaign

Raised in Edmonton, Alberta, when launching his campaign, Carney highlighted his role in helping the government address its debt during the 2008 financial crisis ? and his role in navigating Britain?s economy through Brexit.

Who is Mark Carney, the crisis-handling former central bank governor turned Canada?s next leader?

Carney has zeroed in on bringing economic prosperity to Canada with the help of its natural resources like critical minerals and making Canada a leader in clean energy, stressing that being low-carbon will help Canada be more competitive. He has proposed shifting the financial burden of the carbon tax from consumers to big corporations and has said that under his leadership, the tax Canadian consumers and small businesses pay on fuel would be replaced with incentives to reduce carbon emissions.

Carney has not shied away from questions on how to tackle the Trump administration.

Since the US tariffs were announced last month, Carney has been an outspoken proponent of dollar-for-dollar retaliatory tariffs that would hit the US hard but have minimal impact on Canada.

After Trump?s tariff announcement and accusations of fentanyl trafficking from Canada into the US, Carney told CNN last month he was ?offended? given Canada?s long friendship with the US.

?We are a proud, independent nation. We view ourselves as the greatest country on Earth. We have been insulted on multiple occasions by senior members of the administration. We are not going to reciprocate in those insults.? (CNN, excluding headline)
