The Grey Nuns are a religious order founded in 1737 by Saint Marguerite d'Youville in Montreal, Canada. Their mission focuses on providing care and support to the poor and sick, particularly in the areas of education and healthcare. The order is known for its distinctive grey habits, which symbolize their commitment to humility and service. Over the years, the Grey Nuns have expanded their work across Canada and the United States, establishing hospitals, schools, and orphanages. They have played a significant role in the development of social services in these regions, embodying the values of compassion and charity in their daily lives.
