President-elect Donald Trump's promise to slap an across-the-board tariff of at least 10 per cent on all imports including from Canada is unlikely to apply to Canadian oil, energy experts are predicting.

The threat of the tariff is causing a lot of concern north of the border, where the Canadian Chamber of Commerce said such a tariff could take a $30-billion bite out of the Canadian economy.

Donald Trump's second administration is filling up with some of his most loyal supporters and many of the people landing top jobs have been critical of Prime Minister Justin Trudeau and security at Canada's border.

One expert says there are not many Canadian allies, so far, in the president-elect's court.

"I don't see a whole lot of friends of Canada in there," said Fen Hampson, a professor of international affairs at Carleton University in Ottawa and co-chair of the Expert Group on Canada-U.S. Relations.

Donald Trump clinched the United States election after a tumultuous campaign as Canadian officials espoused the important relationship between neighbours in congratulations to the former president on his extraordinary comeback.

"I will govern by a simple motto: promises made, promises kept," Trump said to cheering party faithful at a Florida watch party.

Trump was elected the 47th president of the U.S. amidst a deeply divided America by prevailing among voters in the key battleground states.

Prime Minister Justin Trudeau is extending congratulations to Donald Trump on his re-election as president of the United States. 

Trump staged a major political comeback, securing the necessary 270 electoral college votes to win the presidency in the early hours of Wednesday morning. 

This concludes a turbulent campaign for Trump, which included being convicted of 34 felonies in a hush-money case and two assassination attempts. 

Former president Donald Trump is poised to return to White House after a polarizing U.S. election that deeply divided the country.

The U.S. election on Tuesday saw Trump post early wins in critical states by taking Pennsylvania, North Carolina and Georgia. 

Vice-President Kamala Harris did not appear at her election night party at her alma mater Howard University in Washington. 

Top aides told the audience that Democrats would continue overnight to fight to make sure that every vote is counted.

Millions of Americans are heading to the polls Tuesday as a chaotic presidential campaign reaches its peak in a deeply divided United States, where voters in only a handful of battleground states will choose the country’s path forward.

Vice-President Kamala Harris and former president Donald Trump have presented starkly different visions for America's future, but polling shows the two remain in a dead heat. 

Prime Minister Justin Trudeau says that at a time when the world faces increasing instability, leaders have a choice: bury their heads in the sand or put their differences aside for the sake of future generations.

"We can recognize that, collectively, we have a responsibility to set our differences aside, to confront the serious global challenges, and to deliver on a pact for the future," Trudeau said at the Summit of the Future in New York on Sunday. 

Prime Minister Justin Trudeau is set to be in New York this week for the 78th meeting of the United Nations General Assembly and the Summit of the Future amid increasing geopolitical instability around the world.

"Canada will have a leading role in making the world fairer and more prosperous," Trudeau said in a news release last week. "I look forward to working with other leaders to accelerate progress on our shared priorities and build a better future for everyone."

Kamala Harris pushed back on Donald Trump's claims about immigration and abortion as the two leaders met face-to-face for the first time on a debate stage in Philadelphia Tuesday.

The matchup marked a pivotal moment during the final sprint of a close race for the White House and saw Trump and Harris lay out starkly different visions for the future of America. 

While it started with a handshake, the debate quickly saw the Democratic vice-president and Republican former president zero in on each other's records. 

The U.S. Department of Homeland Security says people seeking asylum at the border with Canada will have less time to consult a lawyer before making their case, as President Joe Biden's asylum halt makes its way to Canada’s doorstep. 

Biden announced sweeping changes mostly targeted at the U.S. border with Mexico in June, as the issue remains a thorn in the Democrats' side ahead of the November election. The new procedural changes, which the department confirmed Tuesday, will affect migrants crossing into the U.S. from Canada.
