Security at 24 Sussex was overhauled following a November 1995 attempted assassination by André Dallaire, who wandered around the house and grounds for nearly an hour before being confronted outside Jean Chrétien's bedroom by the Prime Minister's wife, Aline; she locked the door to the bedroom while Jean guarded it with an Inuit stone carving. Ultimately, Royal Canadian Mounted Police officers arrested Dallaire. Measures put in place after the attempted assassination include the addition of several more guards and security cameras to the house's attaché, and the installation of crash-proof barriers within the main gates.
