In the small world in which the Congregation had its beginnings, the sisters had no difficulty in remaining in touch with their former students. Even then, however, they did not rely only on informal contact but held meetings of the older girls and women on Sundays. In the course of the years they also organized groups like the Congregation of Notre-Dame-de-la-Victoire and the Oeuvres des Tabernacles.
In the first quarter of the 19th century alumnae groups became attached to Congregation schools in Bourbonnais, Kankakee, New York, Staten Island, Saint-Louis de Kent, Ottawa, Sherbrooke and Sainte-Thérèse and, in Montreal, at the Pensionnat Sainte-Catherine, Villa Maria and École Normale Jacques-Cartier. In 1929 a federation of former students of Catholic Convents was created for Canada with the blessing of the Pope and the approbation of the Canadian bishops. The “amicales” or associations of Congregation schools were given the generic name “Notre-Dame” to which each added its own identifier. They were governed by a common constitution and rules and sent delegates each year to a meeting held at the Mother House on the Saturday before the feast of the Ascension.
These associations served as study circles, organized social events for their members and used their resources for works of charity and for Catholic social action. The association of Catholic Convents became, in 1935, the FDAC, the Fédération diocésaine des Amicales des couvents, with directives supplied by the various dioceses.
