Ian Brodie, ex-chief of staff to the former Conservative prime minister Stephen Harper, told POLITICO: “I don’t remember the last time I saw a prime minister call an election … and yet be so unprepared for it”.
He added: “The surprise of the election is that Trudeau has just looked frozen.”
Some see Mr Trudeau’s decision to call a snap election as a thinly veiled attempt to secure a greater majority in Parliament.
Mr Trudeau led his party to victory in two elections – a majority win in 2015 and a minority government in 2019.
Liberals in the past won over voters by painting the Conservatives as non-progressive.
