King Charles III and Queen Camilla will visit Canada, where the monarch is head of state, from May 26-27 and attend the opening of parliament, Buckingham Palace said Friday.
"The King, accompanied by The Queen, will attend The State Opening of the Parliament of Canada, in Ottawa," a statement read.
Canadian Prime Minister Mark Carney, winner of this week's general elections, said the visit would be "an historic honor which matches the weight of our times".
The king hosted Carney at Buckingham Palace in March, at a time when US President Donald Trump was issuing threats against the Commonwealth nation.
It will be Charles' first visit to Canada since becoming king in 2022 and his first trip to a Commonwealth country since touring Australia and Samoa in October.
That visit saw a much-reduced schedule, being the first foreign trip since the king was diagnosed with an unspecified cancer in February 2024.
He is still receiving weekly treatment, but recently completed a visit to Italy.
