FILE-- Natural Resources Minister Lisa Raitt carries documents at a news conference in Ottawa, in this May 28, 2009 photo. CTV News says Raitt or one of her aides left behind sensitive government documents at the network's headquarters in Ottawa. The report says the documents, some of which were marked “secret”, show Ottawa has poured far more money into the aging Chalk River nuclear reactor than the public has been told.
