The leader of the most populous Canadian province and the heart of her vital car industry said on Friday that he would convene early elections because he needed a stronger hand to cope with the Plan Trump to introduce customs on Canadian exports.

“With a strong term, we will be able to fight Donald Trump to make sure we will stop the customs,” said Doug Ford, a conservative Prime Minister of Ontario, at a press conference on Friday.

Mr. Ford appeared as one of the strongest political votes defending Canada by Mr Trump, who claims that Canada has an unfair economic advantage over the United States.

“He will try to ravage our country,” Mr. Ford told the US president to reporters.

Ontario car industry is deeply intertwined with the one in the United States, with parts and components that change many times before driving completely composed.

A 25 percent general customs that Mr Trump said he would apply on February 1st would decimate the Canadian economy – the province could lose as many as 500,000 jobs, according to Mr. Ford.

Ontario is also a large manufacturer of hydroelectric energy that flows across the border and supplies energy to new England, something Mr. Ford said that the province could deny it as a form of retribution.

“We will go to the point of excluding their energy,” he said recently.

At such a potentially dangerous moment, Mr. Ford said that Canada was restrained by a lack of strong negotiating position at the federal level, partly because Prime Minister Justin Trudeau decided to deviate and make room for a new party leader and prime minister.

“You need a voice at the table,” Mr. Ford said.

Mr. Ford’s party already has most places in the legislative body of Ontario, but he signaled that the increase in the number of conservatives would strengthen their ability of aggressive action in the turbulent political climate with the United States, the largest trade partner of Canada.

“The opposition treats you with a little more respect instead of being vulnerable,” Mr. Ford said. The election will now take place on February 27, more than a year before the fixed date of election in June 2026.

Opposition leaders said that early elections were unnecessary because they would support Mr. Ford in the defense of the province and the country against customs.

G. Ford toured US cable programs, including Fox News, to criticize Mr Trump over customs. He also launched an advertising campaign worth a million dollars, reminding viewers of the contribution of Ontario energy and minerals of the United States.

Mr. Trump repeated his threat to customs on Thursday in remarks he gave to the participants of the Economic Forum in Davos, Switzerland, saying that the United States did not need Canadian export products such as wood materials, oil and gas.

“We have our own,” Mr. Trump said.
