Ahead of the election, support for the Conservatives outpaced the Liberals by 44% to 31.2% among 18 to 34 year olds, a Nanos poll on 25 April indicated.

The issues that resonated with Canadians depended on age, too. Carney campaigned heavily on standing up to Trump, while affordability and a broken "Canadian promise" were central to Conservative leader Pierre Poilievre's message.

Abacus Data polling indicated about 18% of 18 to 29 year olds were worried about Trump. That jumped to 45% for voters over 60, suggesting a diversion on key issues between generations.

A big challenge for Carney and the Liberals will be how they can win back the confidence of those younger voters, Mr Coletto said, who "feel really let down and frustrated".
