André Dallaire (born 1961) is a Quebecois man who attempted to assassinate Canadian Prime Minister Jean Chrétien in 1995. Dallaire claimed that he heard voices that led him to break into the 24 Sussex Drive residence. At trial, Justice Paul Bélanger agreed with Dallaire's earlier diagnosis of paranoid schizophrenia and found Dallaire guilty of attempted murder, but not criminally responsible.
Born in Longueuil, Quebec, Dallaire was diagnosed as having paranoid schizophrenia at sixteen years of age. He had quit his job at a Montreal convenience store on October 25, 1995, removing all the money out of the cash register and walking off mid-shift. On October 30, his sister reported receiving a letter from him that had been postmarked in Ottawa.
At 02:10 UTC−5 on November 5, 1995, Dallaire arrived outside 24 Sussex Drive and spent the next 20 minutes throwing stones onto the grounds and waving at security cameras while carrying a pocket knife alternately described as three or five inches in length (7.6 to 12.7 cm).
He then climbed the fence and strode over to the house, where he smashed a glass door and entered, wandering around the basement and ground floor for 30 minutes before heading to the Chrétiens' bedroom, where he was confronted by Chrétien's wife Aline as he was pulling on his gloves. Aline hurried back into the bedroom and locked the door, rousing her husband, who initially dismissed her story as "just a dream", while she dialled the RCMP officers stationed outside the house. Stories diverged as to whether Jean or Aline Chrétien brandished an Inuit stone sculpture of a loon in case Dallaire broke through the door.
