A new report from the World Economic Forum says Canada has slipped to the bottom of a ranking of the 10 most competitive countries in the world, despite the fact it weathered the recession better than most. The report ranks 139 global economies on their productivity and ability to compete. It bumped Canada down one spot to 10th from 9th a year ago, citing a “stable” performance in the past year. How can Canada climb the ranks again? “Improving the sophistication and innovative potential of the private sector, with greater R&D spending and producing higher on the value chain, would enhance Canada’s competitiveness and productive potential going into the future,” the report said. Switzerland leads the rankings again in 2010, followed by Sweden and Singapore. At the bottom of the top ten: Germany, Japan, Finland, the Netherlands, Denmark and Canada.
