Jornal Do Brasilia - Canada deputy PM quits in tariff rift with Trudeau

Freeland also stepped down as finance minister, and her resignation marked the first open dissent against Prime Minister Trudeau from within his cabinet and may threaten his hold on power.

Liberal Party leader Trudeau lags 20 points in polls behind his main rival, Conservative Pierre Poilievre, who has tried three times since September to topple the government and force a snap election.

"Our country today faces a grave challenge," Freeland said in her resignation letter, pointing to Trump's planned 25 percent tariffs on Canadian imports.

"For the past number of weeks, you and I have found ourselves at odds about the best path forward for Canada."

First elected to parliament in 2013, the former journalist joined Trudeau's cabinet two years later when the Liberals swept to power, holding key posts including trade and foreign minister, and leading free trade negotiations with the EU and the United States.

Most recently, she had been tasked with helping lead Canada's response to moves by the incoming Trump administration.

Canada's main trading partner is the United States, with 75 percent of its exports each year going to its southern neighbor.

In her resignation letter, Freeland said Trudeau wanted to shuffle her to another job, to which she replied: "I have concluded that the only honest and viable path is for me to resign from the cabinet."

As finance minister, she explained the need to take Trump's tariffs threats "extremely seriously."

Warning that it could lead to a "tariff war" with the United States, she said Ottawa must keep its "fiscal powder dry."

"That means eschewing costly political gimmicks, which we can ill afford," she said in an apparent rebuke of a recent sales tax holiday that critics said was costly and aimed at bolstering the ruling Liberals' sagging political fortunes.

- Trouble for Trudeau -

Dalhousie University professor Lori Turnbull called Freeland's exit "a total disaster."

"It really shows that there is a crisis of confidence in Trudeau," she said. "And makes it much harder for Trudeau to continue as prime minister."

Until now, the cabinet has rallied around Trudeau as he faced pockets of dissent from backbench MPs, noted Genevieve Tellier, a professor at the University of Ottawa.

Freeland's rejection of his economic policies poses "a big problem," she said, and shows his team is not as united behind him as some thought.

Freeland's departure comes on the same day she was scheduled to provide an update on the nation's finances, amid reports the government would blow past Freeland's deficit projections in the spring.

"This government is in shambles," reacted Poilievre's deputy leader, Andrew Scheer, to Freeland's news, saying "Even she has lost confidence in Trudeau."

Housing Minister Sean Fraser, who also announced Monday he was quitting politics, described Freeland as "professional and supportive."

One of her closest friends and allies in cabinet, Anita Anand, told reporters: "This news has hit me really hard."

Freeland said she would run in the next election, expected in 2025.
