The Heritage Building was built in 1874. It was a school: the Ottawa Normal School. The building was used to train elementary school teachers.
It is now part of the Ottawa City Hall and was renamed the Heritage Building.
However, it seems that this place is haunted by the ghost of Eliza Bolton, one of the first teachers in this college.
For many years, the janitors of the building have reported strange events: major temperature drops, unusual shadows, etc.
Many people even think that the paranormal activities encouraged the school administration to leave the building and to close it down.
