Canada’s new Prime Minister Mark Carney yesterday called early elections for April 28, pledging to defeat Donald Trump’s drive to annex the United States’s huge northern neighbour.Carney, a former central banker, was chosen by Canada’s centrist Liberal Party to replace Justin Trudeau as prime minister, but he has never faced the country’s broader electorate.That will now change as Carney brought parliamentary elections forward several months from October, and he made it clear that the barrage of trade and sovereignty threats coming from the US president will be the focus of his campaign.“I’ve just requested that the governor general dissolve parliament and call an election for April 28. She has agreed,” Carney said in a speech to the nation, referring to King Charles III’s representative in Canada, a member of the British Commonwealth.In power for a decade, the Liberal government had slid into deep unpopularity, but Carney will be hoping to ride a wave of Canadian patriotism to a new majority.“I’m asking Canadians for a strong, positive mandate to deal with President Trump,” Carney said, adding that the Republican “wants to break us, so America can own us. We will not let that happen.”“We are facing the most significant crisis of our lifetimes because of President Trump’s unjustified trade actions and his threats to our sovereignty,” Carney said.“Our response must be to build a strong economy and a more secure Canada,” he added, pledging not to meet Trump until the US leader recognises Canadian sovereignty.Trump has riled his northern neighbour by repeatedly dismissing its borders as artificial, and urging it to join the United States as the 51st state.The ominous remarks have been accompanied by Trump’s swirling trade war, with the imposition of tariffs on imports from Canada, which could severely damage its economy.Domestic issues such as the cost of living and immigration usually dominate Canadian elections, but this time around, one key topic tops the list in this country of 41mn people: who can best handle Trump. The president’s open hostility toward his northern neighbour — a Nato ally and historically one of his country’s closest partners — has upended the Canadian political landscape.Trudeau, who had been in power since 2015, was deeply unpopular when he announced he was stepping down, with Pierre Poilievre’s Conservatives seen as election favourites just weeks ago.But the polls have narrowed spectacularly in Carney’s favour since he took over the Liberals, who only hold a minority in parliament, and analysts are now calling the race too close to call.“Many consider this to be an existential election, unprecedented,” Felix Mathieu, a political scientist at the University of Winnipeg, told AFP.“It is impossible at this stage to make predictions, but this will be a closely watched election with a voter turnout that should be on the rise.”Poilievre, 45, is a career politician, first elected when he was only 25. A veteran tough-talking campaigner, he has sometimes been tagged as a libertarian and a populist.Yesterday, Poilievre — seen by some as too similar to Trump in style and substance — set the tone.“I want the opposite of what Donald Trump wants,” the Conservative leader said, promising to base his campaign on bread-and-butter economic issues and the worries of “regular people.”Carney, 60, has spent his career outside of electoral politics. He spent more than a decade at Goldman Sachs and went on to lead Canada’s central bank, and then the Bank of England.Smaller opposition parties could suffer if Canadians seek to give a large mandate to one of the big two, to strengthen their hand against Trump.As for the US leader, he professes not to care, while pushing ahead with plans to further strengthen tariffs against Canada and other major trading partners on April 2.“I don’t care who wins up there,” Trump said this week.“But just a little while ago, before I got involved and totally changed the election, which I don’t care about [...] the Conservative was leading by 35 points.”
