If I understand you correctly, within the government, no matter the department or agency, the Canadian Security Intelligence Service, the RCMP, Foreign Affairs, the Privy Council, the Department of Transport, the Department of Public Safety or the Prime Minister's Office itself, no one was ever officially informed by the Privy Council Office of Ms. Couillard's shady past. You yourself stated that you were aware last summer of her relationship with ex-minister Bernier. He was minister at the time and you stated that you had done a biennial check in April 2008. You therefore were aware that these two people were involved in a relationship. You therefore were not formally informed by anyone of her murky past, and you only learned about it through the media.
On June 17th, 2008. See this statement in context.
