According to the Ontario Ghosts and Hauntings Research Society… maybe!
‘Activity seems to be that of a very young child. Near the front office is a blackboard with chalk. Chalky hand-prints have been found on the hallway floor and pamphlets have been left in disarray. Activity typically happens over a weekend or when the building is not in use for a long period of time. Staff members return to find the hallway a mess with fliers the witness describes it as ‘fliers covering the entire floor’.’
Intriguing… but I don’t think we quite have enough activity for a full-fledged Don Mills Ghost Walk just yet.
