Marguerite d'Youville died in 1771 at the General Hospital. In 1959, she was beatified by Pope John XXIII, who called her "Mother of Universal Charity", and was canonized in 1990 by Pope John Paul II. She is the first native-born Canadian to be elevated to sainthood by the Roman Catholic Church. Her feast day is October 16. In 1961, a shrine was built in her birthplace of Varennes. Today, it is the site of a permanent exhibit about the life and works of Marguerite. The review process included a medically inexplicable cure of acute myeloid leukemia after relapse. The woman is the only known long-term survivor in the world, having lived more than 40 years from a condition that typically kills people in 18 months.
