They were welcomed to an afternoon program at Parliament Hill by Canadian Prime Minister Stephen Harper who welcomed them as "the world's most famous newlyweds" he also said they represent "our unbreakable link with our past and our unqualified optimism for the future."

As he did the day before William spoke in both French and English about his and Kates family ties to Canada.
Will also said that Kate learned about Canada from her late grandfather, "who held this country dear to his heart for he trained in Alberta as a young pilot during the Second World War."
He spoke of his grandmother, Queen Elizabeth II. The queen, he said, "has asked me to convey her warmest good wishes to the people of Canada, and her happy and abiding memories of being on Parliament Hill with the Duke of Edinburgh one year ago."
Prince William drew a loud cheer from the crowd when he referred to his grandmother as "the Queen of Canada." She is still Canada's head of state. He also said that the she was watching their Canada tour with interest.
Kate was impressively attractive wearing the same dress she wore for the couple's official engagement portrait last year, a cream dress by the London designer Reiss, a brilliant red hat topped with a maple leaf and the Queen's Maple Leaf brooch which Queen Elizabeth loaned Kate for the tour. The brooch was first worn by the then-Princess Elizabeth on her first visit to Canada back in 1951.
Prince William wore a blue suit, light blue colored shirt and a red tie.
There was an estimated 300,000 people gathered to watch the Canada Day show around Parliament Hill. Teh show included a 21-gun salute and military plane flyovers.
Kate mouthed "that scared me" as she put her hand to her heart When two F-18's did a flyby.
Before departing for Canada Day celebrations on Parliament Hill, Will and Kate formally known as the Duke and Duchess of Cambridge spent some time with newly minted Canadians at a citizenship ceremony by giving out flags and shaking hands.
At the Canadian Museum of Civilization hundreds of raucous spectators cheered as the royal couple emerged from their motorcade on Friday 7-1-11.
