In pictures: King Charles and Queen Camilla welcomed in Ottawa

King Charles III and Queen Camilla have arrived in Canada for a visit meant to underscore Canada's sovereignty in the face of tensions with the US.

"The Royal Visit is a reminder of the bond between Canada and the Crown – one forged over generations, shaped by shared histories, and grounded in common values," Prime Minister Mark Carney said in a statement on Monday morning.

The King and Queen will spend the day meeting elected officials and with the community.

On Tuesday, he will deliver the Speech of the Throne, which will lay out the government's priorities and goals, to Parliament.

A monarch has not delivered the throne speech in Canada since 1977, making this royal visit a rare occasion.

Here is a look at King Charles III and Queen Camilla's time in Ottawa so far:

The King and Queen touched down in Ottawa at around 13:15 local time (18:15 BST). They were welcomed by members of the Royal Canadian Mounted Police and the Canadian Armed Forces.

Waiting for them on the runway were Prime Minister Mark Carney, his wife Diana Fox Carney, Canada's Governor General Mary Simon and other dignitaries.

They were also met by national indigenous leaders.

The King wore a dark red patterned tie, while the Queen donned a light pink ensemble from a British designer.

She wore a diamond maple leaf brooch that was given by King George VI to Queen Elizabeth, the Queen Mother, in 1939 ahead of their first royal tour to Canada.

That same brooch was passed down to Queen Elizabeth II, and has been loaned to other royals including Catherine, Princess of Wales.

Carney extended an invitation to the King earlier this year and announced the visit shortly after his Liberal party won the general election in April.

The visit comes amid a trade war with Canada's neighbour and close economic ally, the United States.

US President Donald Trump has also repeatedly said the country would be better off as a 51st US state.

The Queen was given a bouquet of flowers from a local Ottawa youth, and the two royals were greeted by school groups from Ontario and Quebec.

Some of the children are enrolled in the Duke of Edinburgh programme, a global youth development programme that was started by the late Prince Phillip - the King's father - in 1956.

The King and Queen travelled to Lansdowne Park in Ottawa, where they are meeting local community groups and where the King has been invited to participate in a ceremonial street hockey puck drop.

There, a group of well-wishers had gathered in advance of the King's arrival, waving the Union Jack. A few wore shirts that read: "Canadian grown with English roots".
