OTTOWA: King Charles III was set to land in Ottawa Monday for a historic visit to open Canada鈥檚 parliament, a brief trip seen as part of the pushback against US President Donald Trump鈥檚 annexation threats.
The 76-year-old monarch, who is also Canada鈥檚 head of state as part of the Commonwealth, was invited by Prime Minister Mark Carney to deliver the throne speech, an address that outlines the government鈥檚 priorities.
The speech is typically given by the British monarch鈥檚 representative in Canada, the governor general.
Queen Elizabeth II, the king鈥檚 late mother, delivered a throne speech in Canada just twice during her long reign, in 1957 and 1977.
Charles, making his first visit to Canada since his coronation, has never commented on Trump鈥檚 repeated talk of making Canada the 51st US state.
But he will be closely watched for any comments on Canada鈥檚 sovereignty, as well as on trade.
Trump has slapped tariffs on Canadian goods including sector-specific levies on autos, steel and aluminum, rattling the Canadian economy 鈥� though he has suspended some of them pending negotiations.
Queen Camilla will accompany Charles on the 24-hour visit to Ottawa.

Carney has said his newly-elected government has been given a mandate 鈥渢o define a new economic and security relationship with the United States,鈥� a neighbor he believes Canada 鈥渃an no longer trust.鈥�
He has promised to curb reliance on trade with the United States by boosting internal commerce while forging deeper economic ties with allies overseas.
The government鈥檚 path to 鈥渂uild Canada strong鈥� will be outlined in Charles鈥檚 speech, Carney said last week.
A government statement described the visit as 鈥渁 momentous and historic occasion that underscores Canada鈥檚 identity and sovereignty as a constitutional monarchy.鈥�
Trump repeatedly returned to his annexation musings during Carney鈥檚 Oval Office visit earlier this month, insisting it would be a 鈥渨onderful marriage.鈥�
Carney stood his ground, saying Canada was 鈥渘ever for sale.鈥�
Trump鈥檚 envoy to Canada, Ambassador Pete Hoekstra, dismissed the notion that inviting Charles to open parliament was an effective way to make a statement on annexation.
鈥淚f there鈥檚 a message in there, there鈥檚 easier ways to send messages. Just give me a call. Carney can call the president at any time,鈥� he told the public broadcaster CBC last week.
Hoekstra added that he sees the annexation issue as being 鈥渙ver.鈥�
鈥淢ove on. If the Canadians want to keep talking about it 鈥� that鈥檚 their business.鈥�

Charles and Camilla are scheduled to land in Ottawa on Monday afternoon.
They鈥檒l be received by Governor General Mary Simon, Carney, Indigenous leaders and other dignitaries before meeting community organizations in Ottawa.
Charles also holds an audience with Carney on Monday.
At the Senate on Tuesday, the monarch will receive full military honors before delivering the throne speech.
Canadian royal commentator Edward Wang told AFP he was traveling from his home in the west coast city of Vancouver to Ottawa for the visit.
鈥淎t a time when the sovereignty of our country is being challenged, having our head of state open the first session of a new Parliament sends a signal,鈥� he said.
鈥淭he entire world will be watching.鈥�
