Sun Youth may soon need to move out of the building it has been in since the early 1980's.
The building on Saint-Urbain used to be Baron Byng High School and is now owned by the Commission Scolaire de Montreal.
The board says it's expecting a big influx in students in the coming years and needs the space.
Commissioners vote next Wednesday on whether to take the building back, which would force the charity to find a new home within the next 18 months.
Sun Youth says ideally they'd like to stay exactly where they are or at least in the same general area.
