In 1948, feeling threatened by Joseph Stalin's regime, Olga and her immediate family relocated to a farm in Campbellville, Ontario, Canada. With advancing age, Olga and her husband moved to a bungalow near Cooksville, Ontario. Colonel Kulikovsky died there in 1958. Two years later, as her health deteriorated, Olga moved with friends to a small apartment in East Toronto. She died aged 78, seven months after her older sister, Xenia. At the end of her life and afterwards, Olga was widely labelled the last Grand Duchess of Imperial Russia.
