Its main predecessor is the Montreal Catholic School Commission (Commission des écoles catholiques de Montréal or CÉCM) which was composed of both French and English Roman Catholic schools and had been in operation for over 150 years.
The Mouvement pour une école moderne et ouverte keep all positions; president (Catherine Harel-Bourdon) and the 13 new chairs.
In November 2014 Yves Bolduc, the Minister of Education, Recreation and Sports of Quebec, suggested moving Ahuntsic – Cartierville, Côte-des-Neiges, Notre-Dame-de-Grâce, Le Sud-Ouest, and Westmount from the CSDM to the Commission scolaire Marguerite-Bourgeoys (CSMB),[4] which would move 66 schools away from the CDSM,[5] and therefore 30% of the total students of the CSDM.
[4] Some students would also move to the Commission scolaire de la Pointe-de-l'Île (CSPÎ).
[6] François Cardinal of La Presse criticized the deal, saying that it was penalizing the CSDM and unfairly rewarding the CSMB.
