The scale of what lurks beneath the surface could be vast – can the Liberal leader defy the odds and win a fourth term?

Justin Trudeau, who promised “sunny ways” as he won an election on a wave of public fatigue with an incumbent Conservative government, is now facing his darkest and most uncertain political moment as he attempts to defy the odds – and a bitter public – to win a rare fourth term.

The Canadian prime minister appears to have ignored both the demands of a handful of his own MPs calling for him to resign and threats from a separatist party looking to unravel his party’s tenuous hold on power.

Yves-François Blanchet says Liberals must pass legislation or lose support of party propping up government

The leader of the Quebec independence party propping up the government of Justin Trudeau has insisted that the political lifeline depends on the quick passage of two pieces of legislation, and warned Canada’s embattled prime minister that he remains “very vulnerable”.

The Bloc Québécois leader, Yves-François Blanchet, told the Guardian the Liberals must act swiftly to enshrine protections for dairy farmers and boost payments to seniors to stave off a fatal vote of non-confidence. He warned that unless both pieces of legislation are passed into law by 29 October, his party would begin discussions with other parties to trigger a federal election.

Canada’s ruling Liberal party has lost a once-safe seat in Montreal, a result that is likely to put more pressure on the prime minister, Justin Trudeau, to quit.

Elections Canada said that with 100% of the votes counted in the parliamentary constituency of LaSalle-Émard-Verdun, the separatist Bloc Québécois candidate, Louis-Philippe Sauvé, had beaten the Liberal candidate, Laura Palestini, by a whisker: 28% to 27.2%. The New Democratic party (NDP) candidate received 26.1%.

NDP leader Jagmeet Singh made the surprise announcement on social media on Wednesday afternoon, accusing Trudeau of “caving” to corporate greed. “The Liberals have let people down. They don’t deserve another chance from Canadians,” he said.
