Prince William and Kate Middleton got their hands dirty during day three of their visit to Canada today. Prince William and Kate Middleton, the Duke and Duchess of Cambridge, planted a ceremonial Hemlock tree on the grounds of Rideau Hall in the shadow of an Oak put there by his parents, Prince Charles and Princess Diana, on William's first birthday on June 21,1983. Kate and Will's sapling is a symbol of their love, and even with a shovel in hand she once again looked perfectly put together in a gray Catherine Walker dress and sparkly shoes for the beautiful ceremony. Kate and William also unveiled a mural by Augustus John at the Canadian War Museum before traveling to the next spot on their Canadian journey. Kate and William departed Ottawa and made an appearance in Montreal, where Kate made time to speak to a young girl in the children's cancer ward at the Sainte-Justine University Hospital. Kate Middleton's Canada tour fashion has been refreshing and exciting over the first few days of their North American tour, and all eyes are on the Duchess as the world watches to see what she will wear next.
