Canadian Prime Minister Mark Carney has said he will travel to Washington next Tuesday to meet Donald Trump after an election campaign in which he accused the US President of trying to break Canada.
Mr Carney said he expects difficult but constructive discussions with Mr Trump.
Mr Trump, who muses about annexing Canada, has imposed tariffs on some Canadian goods.
Mr Carney regularly termed the US actions as a betrayal and during the campaign said he would push for talks on creating new security and defense ties.
"Our focus will be on both immediate trade pressures and the broader future economic and security relationship between our two sovereign nations," Mr Carney told a news conference after his recent election victory.
"Our old relationship, based on steadily increasing integration, is over. The questions now are how our nations will cooperate in the future and where we in Canada will move on," Mr Carney said.
Mr Carney, an ex-central banker, said his experience in crisis management meant he was the best person to tackle Mr Trump.
The Liberals, who had trailed badly in the polls as recently as January, rebounded to win Monday's election.
Mr Carney also says Canada must reduce its reliance on the United States, which takes 75% of all Canadian exports.
Meanwhile, Mr Carney promised to launch the greatest transformation of Canada's economy since the end of the World War II during his first press conference after his election victory.
He vowed "the biggest transformation of our economy since the end of the Second World War," adding that it "will be an incredibly exciting time as we take control of our economic destiny."
