Canadian Prime Minister Justin Trudeau is increasingly likely to announce he intends to step down, though he has not made a final decision, a source familiar with Trudeau's thinking said on Sunday. The source spoke to Reuters after the Globe and Mail reported that Trudeau was expected to announce as early as Monday that he would quit as leader of Canada's ruling Liberal Party after nine years in office.

In mid-December, Chrystina Freeland, the deputy prime minister and head of finance, unexpectedly resigned citing disagreements over the handling of Trump’s suggested 25 percent tariffs on the country – an issue that could damage the economy of both countries.
