Michael Petruccelli says; The U.S. debt mess is taking a toll on Canadian exports. Canada's dollar is heading toward a 2011 high in coming months as investors seek a safe parking place while the debt ceiling debate plays out in Washington. Pricier Canadian products mean U.S. demand for them will continue to fall, and purchases are already down because of Americas slow recovery from recession. But Canada's economy continues to grow. With a 3.2% boost this year and a 3.1% jump next year. Among the bright spots: retail, construction & mining.
