In October 2026, École secondaire Jeanne‑Mance on the Plateau‑Mont‑Royal reported operating at roughly 80 % of its capacity, leaving about 400 places unfilled.
The situation stands in stark contrast to many other Montreal schools, where enrollment exceeds available space and occupancy rates surpass 100 %.
Spokesperson Violette Cantin noted that the school currently has 400 free places, underscoring the lower demand on the Plateau compared with the rest of the city.
