Mark Carney will be sworn in officially as prime minister and reveal the makeup of his first cabinet on Friday morning — a team one government source said will not include Jean-Yves Duclos.

A major foreign-policy summit is underway in Quebec today, with the Liberals welcoming foreign ministers from the U.S., Europe and Japan.

U.S. President Donald Trump's stiff duties have been temporarily paused on some Canadian products, bringing little relief as the tariff threat continues to hang over America's closest neighbour.

Carney is the presumed front-runner for the party's leadership and could become prime minister as early as next week — which would make Trump's growing trade war with Canada his problem to sort out.

A day into Donald Trump's North American trade war, the U.S. president remained adamant that tariffs would benefit America even as a key member of his team has floated that a compromise could materialize Wednesday.

In a news release late Monday, Trudeau said if U.S. tariffs come into effect as Trump planned, Canada will respond with 25 per cent tariffs on $155 billion worth of American goods.

Canadians are waking up to a new and uncertain reality after U.S. President Donald Trump's deadline for economy-wide tariffs passed with no relent overnight, triggering a continental trade war.

"We could potentially use (this) as a way of signalling the seriousness with which the Government of Canada is viewing this unwelcome talk," said University of Victoria international relations professor Will Greaves.

Canada's aid sector is bracing for cataclysmic suffering worldwide, and is asking Ottawa to help fill gaps as Washington winds down the U.S. Agency for International Development.

U.S. President Donald Trump's "America First" changes to foreign policy could have drastic consequences for Canada's approach to aid, trade, intelligence and diplomacy.

A trio of federal cabinet ministers is in Washington today making a last-ditch attempt to stop U.S. President Donald Trump from imposing economically devastating tariffs on Canadian imports.

One of the seven Liberal leadership hopefuls says the party is not allowing him to run, as another high-profile cabinet minister endorsed Mark Carney on Sunday.

On Tuesday, Indigenous Services Minister Patty Hajdu, Crown-Indigenous Relations and Northern Affairs Minister Gary Anandasangaree and former housing minister Sean Fraser all threw their support behind Carney on social media.

Earlier in the day, cabinet ministers were careful not to declare victory after Trump was sworn into office without mentioning Canada at all, and with no sign of the punishing tariffs he's been threatening since the November election.

Trump has pledged to sign an executive order on inauguration day to impose 25 per cent tariffs on products from Canada and Mexico.
