It was a polite start, with four leaders welcoming each other and agreeing on the need to stand up to President Donald Trump’s threats.

But each had a particular tactic to press home their talking points. Poilievre kept pointing to a decade of Liberal rule as the root of all Canada’s problems. Carney tried to draw a very clear line between himself and Justin Trudeau with policies which drew on his years of experience as a banker and economist.

Singh's answers kept bringing it back to the lives of Canadians with stories from his own trips to the grocery store to the worries of healthcare workers.

Blanchet was the punchiest, accusing his rivals of everything from "very creative numbers" to nonsense and fairy tales.

Their differences were highlighted when each leader was asked to name the top security threat. Poilievre chose rampant gun crime, Carney mentioned China, Singh highlighted illegal guns and drugs and cuts to social services, and Blanchet cited security dependence on the US.

This debate underlined how Canada confronts issues facing countries everywhere – a housing crisis; a climate emergency, immigration pressures, gun crime, President Trump’s tariffs and more. "In a crisis you need a team," Carney emphasized, but asked: "Who will lead?"

This debate will have helped Canadians make up their mind.

Blanchet : Quebec and Canada as a whole should be economic partners, and he can be the voice to put them as equals in front of Trump.

Yves-Francois Blanchet - He says all the leaders should have been quicker to discuss how Quebec and Canada would be partners to deal with Trump.

Jagmeet Singh - The NDP leader regrets not being able to meet as many people as he would have wanted to because it's such a short campaign.

Mark Carney - He says Canada is an amazing country, and regrets not being able meet Canadians across the country over such a short period of time.

He goes on to outline what he sees as threats to Canada, including China, Russia and the United States.

Singh accuses Carney of tax-dodging published at 01:48 British Summer Time

Jagmeet Singh, NDP leader, is first up in leaders' choice.

He says Carney, who is chair of Brookfield Investments, is one of the biggest tax-dodgers in Canada. He expects this of the Conservatives, but not the Liberals.

He asks Carney: Whose side are you really on?

"I'm on the side of Canadians," Carney says.

He has a track record of public service for Canada, Carney says, and says he is also proud of his career in the private sector.

But Singh pushes back: Who have you served? He says the Liberals have prioritised not people, but billionaires.

Carney defends the Liberals record, and says they will build the country "in a way that has not been seen before".

Yves-Francois Blanchet also attacks Mark Carney for his role at Brookfield.

He says Carney wants to support the oil and gas industry, prefab housing, nuclear reactors - all things that Brookfield invests in - and accuses the Liberal leader of "hiding" billions of the company's dollars in Bermuda and the Cayman islands. Will you reveal the details of all your assets before the election? he asks Carney.

Mark Carney says Brookfield is a "Canadian success story", saying Canadian and Quebec pensioners, firefighters, and all Canadians benefit from its investments. He says he always "acted with integrity" and followed all the rules.

"Tell us what you own!" Blanchet replies.
