Poilievre said he was "embarrassed" to watch Prime Minister Justin Trudeau get treated like "a human piñata" at this week's NATO leaders' summit over Canada's defence spending.

Prime Minister Justin Trudeau pushed back on reports of tension between his office and the finance minister, reaffirming his 'full confidence' in Chrystia Freeland.

New measures to support Ukraine are set to be announced during the summit and officials say it will include information on the country’s efforts towards NATO membership.

Canada will be reassuring allies of its commitment to NATO when the prime minister heads to Washington, D.C., this week for a summit of the alliance's leaders.

Former foreign affairs minister Marc Garneau, now 75, was first elected in 2008 as the Liberal MP for the Montreal riding of Westmount-Ville Marie.

Amid questions around his political future, Prime Minister Justin Trudeau said last week's Toronto byelection loss 'was challenging' and should be taken 'seriously.'

Calls have intensified for Justin Trudeau to resign as head of the party he almost single-handedly pulled back from the brink after a decimating electoral defeat in 2011.

'The Liberal party isn't about one person. It's about the values it stands for and it's about improving the lives of Canadians,' a former Liberal cabinet minister said.

Ipsos polling done exclusively for Global News shows 70 per cent of Canadians agree 'Canada is broken,' a charge Conservative Leader Pierre Poilievre repeatedly makes.

Federal Immigration Minister Marc Miller said Wednesday that Liberals need to "step back and give our heads a shake" after this week's byelection upset.
