Guergis was forced to resign from the Cabinet of Canada and leave the Conservative Party caucus on April 9, 2010, pending a Royal Canadian Mounted Police investigation into "serious" but unspecified allegations regarding her conduct. While the RCMP investigated, and eventually concluded there was no evidence of criminal wrongdoing, Guergis continued to sit as an Independent Conservative in the House of Commons. She applied unsuccessfully for reinstatement to the Tory caucus. Guergis was defeated while running as an independent in the 2011 election by Kellie Leitch, her replacement as the riding's Conservative candidate.
