Prince William and Kate boarded a Canadian Forces plane earlier today at Heathrow Airport and are now on their way to Ottawa for the start of their 9 day Canadian tour. After which they will visit California in the USA.
The Duke and Duchess of Cambridge are 'touring' Canada as oppose to 'visiting' the USA because Canada is part of the Commonwealth, in other words it is because Queen Elizabeth II is the head of state for Canada.
William and Kate will travel to Quebec, Prince Edward Island, The Northwest Territories and Alberta before leaving for the US on the 8th July.
When this Royal tour was first agreed last year, Prince William was not married and since the Royal Wedding on 29th April 2011 much has changed. The main change of course is the raised level of international interest in the Royal couple. To put it into perspective, when The Queen visited Canada in the Summer of 2010 there were just 20 international journalists accredited to cover the tour. More than 1,300 journalists have been accredited to cover this Royal tour of Canada by The Duke and Duchess of Cambridge.
More to follow once the Royal couple have arrived in Canada.
