LONDON - The Queen is planning another visit to Canada.

Canadian officials say she will make her 24th official visit to Canada sometime this year or next. Word of the visit came after the Queen hosted a lunch for Prime Minister Stephen Harper, Australian Prime Minister Kevin Rudd and their wives at Buckingham Palace.

No additional details were provided.

The Queen, who turns 83 later this month, was last in Canada in 2005, when she and Prince Phillip visited Saskatchewan and Alberta for their provincial centennials.

Harper, who is in London for the Group of 20 economic summit, also met briefly today with Prince Charles
