Wearing classic, near-matching dark suits, Prince William and Kate, the Duke and Duchess of Cambridge, boarded a flight at 6:20 a.m. ET Thursday. They’re scheduled to land in Canada’s capital at 2 p.m. aboard a Canadian Forces plane.

William and Kate will head straight to the National War Memorial to be greeted by Prime Minister Stephen Harper and his wife, Laureen, at 2:30 p.m. to lay a wreath at the Tomb of the Unknown Soldier.

They’ll also meet the country’s Silver Cross mother — a woman chosen to represent the mothers of all soldiers killed in service of Canada — and greet the public on the way to their car.

Within 90 minutes of arriving on Canadian soil, the two will be on to their second engagement — at Rideau Hall for their official welcome to Canada. They’ll be greeted by Gov. Gen. David Johnston and his wife, Sharon, then walk up the lawn to the front of the residence.

William, last in Canada when he was 15 years old, will make a speech in his first remarks in Canada, at the Governor General’s residence. It’s expected William will speak French for part of his speech — on a day his mother, Diana, the late Princess of Wales, would have turned 50 and Canada turns 144.
