BBC News - Duke of Edinburgh on three-day visit to Canada 27 April 2013 Last updated at 03:39 The Duke of Edinburgh has arrived in Toronto on a brief visit to Canada where he will present a regiment with a new ceremonial flag. Prince Philip will present new colours as colonel-in-chief to the 3rd Battalion, The Royal Canadian Regiment. The Queen's husband left London on an aircraft provided by the Royal Canadian Air Force, and will return on Sunday. Philip, 91, has been hospitalised three times in the past 18 months after suffering health scares. A Buckingham Palace spokesman said: "The main purpose of his visit is to present new colours to Canada's 3rd Battalion in his role as colonel-in-chief of the Royal Canadian Regiment." It is the prince's first major foreign visit since 2011 when he accompanied the Queen on a tour of Australia. This time he has not been joined by the monarch on what the palace has described as a private engagement. His most recent overseas trip was to visit British troops in Germany last May. Following his arrival the duke was presented with the insignia of a Companion of the Order of Canada and Commander of the Order of Military Merit by the Governor General of Canada, David Johnston.
