In August 1921, drastic budget cuts resulted in the decommissioning of "Aurora". She was paid off on 1 July 1922 and disarmed. Her weapons were placed ashore in training facilities and on other active ships. Her crew was reduced to non-manned, much of her up-to-date equipment was salvaged for use in other Canadian warships. "Aurora"s hulk was left alongside a jetty at the Canadian naval base in Halifax until 1927 when her deterioration resulted in city officials demanding the navy move her. The Royal Canadian Navy immediately sold her for scrap in August 1927 to A.A. Lasseque of Sorel, Quebec, and she was broken up.
