On December 28, 2005, a letter surfaced from Royal Canadian Mounted Police (RCMP) Commissioner Giuliano Zaccardelli confirming the force was launching a criminal investigation into whether details regarding government tax policies relating to income trust funds were leaked from the Finance Minister's office. Goodale said he would co-operate completely with any investigation, but would not step aside while the RCMP continued their probe. The investigation dealt only with the Department of Finance, and not the minister himself. On February 15, 2007 the RCMP announced the conclusion of the income trust investigation and laid a charge of 'Breach of Trust' against Serge Nadeau, an official in the Department of Finance, who pleaded guilty in 2010. Goodale was cleared of any wrongdoing, and blamed the NDP's Judy Wasylycia-Leis for sabotaging the Liberals in the 2006 election.
