Charles, Camilla wind down Canada visit Prince Charles speaks to a member of the Guard of Honour during an 1812 Commemorative Military Muster at Fort York Armoury in Toronto, Canada on May 22, 2012. The Prince and his wife Camilla, Duchess of Cornwall, are on a four-day tour of Canada as part of Queen Elizabeth's Diamond Jubilee celebrations. UPI/Christine Chew REGINA, Saskatchewan, May 23 (UPI) -- Britain's Prince Charles and his duchess wife Camilla wound down their fourth and final day of a Canadian visit Wednesday with ceremonies and symphonic music. The heir to the British throne and his wife, the Duchess of Cornwall, were greeted by tolling church bells Tuesday night when they arrived in Regina, Saskatchewan, on a flight from Toronto, the Regina Leader-Post reported. Their agenda Wednesday included a visit to the Indian First Nations University, a luncheon with provincial Lieutenant Governor Vaughn Solomon Schofield and other dignitaries, a closed door meeting with Prime Minister Stephen Harper, capped by an evening with the Regina Symphony Orchestra, the report said. Conductor Victor Sawa told the CBC the performance would focus on Charles' favorites, as requested by his office in London weeks ago. We've got a medley of Beatles, because he like Beatles. His favorite piece is the 'Ride of the Valkyries' from the Wagner opera, so we'll do that too. Charles' and Camilla's tour is part of international global visits this year by the royal family to commemorate the 60th anniversary of his mother, Queen Elizabeth's 60th year as monarch. The couple visited Gagetown, New Brunswick, where Charles trained as a military helicopter pilot in the 1970s, Toronto and Regina. The trip marked Charles' 16th visit to Canada.
