The leaders of Canada's four major federal parties have participated in their second and final debate ahead of this month's general election.

The debate saw discussions on various topics, including the country's ongoing trade war with the US, affordability, crime, and the environment.

Liberal leader Mark Carney, Conservative leader Pierre Poilievre, New Democratic Party leader Jagmeet Singh, and Bloc Québécois leader Yves-Francois Blanchet took part in the two-hour forum.

The leaders were asked about their approach to negotiating with US President Donald Trump and responding to his tariffs on Canada.

They also debated issues such as housing affordability, crime, and healthcare spending.

Carney's opponents criticized him for being part of the same party as former Prime Minister Justin Trudeau, who has been unpopular among Canadians.

Poilievre and Blanchet questioned Carney's ability to bring about change, with Poilievre referencing the 'lost Liberal decade' and Blanchet challenging Carney to prove he is different.

The debate also saw discussions on the leaders' policies on issues such as immigration, taxation, and social programs.

The smaller parties, including the New Democrats and the Bloc, fought for air time and survival, as polls indicate that the bulk of Canadians are opting to support either the Conservatives or the Liberals.

Despite some heated exchanges, the tone of the debate was generally cordial, with the leaders displaying a sense of decorum and civility.
