Canadian Finance Minister Chrystia Freeland, long Prime Minister Justin Trudeau's most powerful minister, announced Monday she was resigning from the Cabinet, as Trudeau deals with declining popularity.

Freeland, who also was deputy prime minister, said Trudeau had told her Friday that he no longer wanted her to serve as finance minister and that he offered her another role in the Cabinet.

But she said in her resignation letter to the prime minister that the only “honest and viable path” was to leave the Cabinet.

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