André Dallaire

In 1998, Dallaire spoke to the media, apologizing for his prior behaviour, and reassuring the Canadian public that he was now on medication that controlled his actions, and that he hoped the Chrétiens could forgive his actions.

In 1998, an intoxicated man was found on the grounds of the Prime Minister's residence, raising questions about the security upgrade undertaken since Dallaire's intrusion.

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 alternatively described as three or five inches in length (7.5 or 12.5 cm).

Dallaire was kept in a group home for the duration of the trial. Expert witness Dominique Bourget, a psychiatrist with the Royal Ottawa Hospital, testified that Dallaire viewed himself as a "secret agent" avenging the loss of sovereigntist forces in the 1995 Quebec referendum, and that he believed killing the Prime Minister would cause him to "become a hero for the nation".

Reporters revisited the 1995 Dallaire breach in August 2014, when there was a break-in at the home of Justin Trudeau, who was then the leader of the Liberal Party of Canada, the party with the third most seats. The Dallaire breach was compared with other Ottawa security breaches in October 2014, after a gunman had killed a soldier and attacked the Parliament buildings. The Dallaire breach was discussed again in October 2015, after the Federal election that made Trudeau Prime Minister. Trudeau did not move into 24 Sussex, the Prime Minister's official residence; the main reasons cited were the fact of the aging residence needing at least ten million dollars in repairs to make it safely habitable, and the site's security.

André Dallaire (born 1961) is a Canadian 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.
