Bank of Canada Governor Mark Carney holds the new Canadian 50 dollar bill, made of polymer, in front of the CCGS Amundsen, the Arctic research vessel depicted on the back of the new bill, in Quebec City, in this March 26, 2012, file photo. Canada is known for the sugar maple, emblazoned on its red-and-white flag, but the Bank of Canada has put what one careful botanist says is a foreign Norway maple leaf on its new currency. The untrained eye might not at first spot the difference between the maple leaf on the new $20, $50 and $100 bills and the sugar maple that is endemic to North America. REUTERS/Mathieu Belanger/Files
