King Charles III arrived in Canada to open a new parliamentary session at the invitation of Prime Minister Mark Carney, a move designed, in part, to send a message to U.S. President Donald Trump about the northern country¡¯s sovereignty.

A greeting party of Canadian officials, Indigenous leaders, schoolchildren and an army regiment known as the Royal Canadian Dragoons met Charles at Ottawa¡¯s airport Monday, along with a large contingent of TV cameras and journalists.

The pageantry of the occasion also came with subtle nods to the fraught politics, coming after Trump¡¯s repeated calls for Canada to become the 51st U.S. state. Queen Camilla wore the Queen Mother¡¯s Diamond Maple Leaf Brooch, which was first gifted by King George VI to his wife ahead of their 1939 royal tour to Canada.
