O Canada! Kate and Will attend the welcome ceremonies for Ottawa's Canada Day festivities on July 1. Topped with a maple leaf-inspired fascinator, The Duchess of Cambridge coupled the crimson hat with the same Reiss dress she wore for her engagement portrait. Addressing the crowd of thousands, William said, "Catherine and I especially are so thrilled and excited by the prospect of the next eight days of being part of the Canadian family. It will be an adventure we will never forget."
