Inglenook is located in the oldest continually-operated school building in the Toronto District School Board. Originally Sackville Street School, it was designed by William G. Storm. The first principal of Sackville Street School (which replaced Palace Street School at the corner of Front and Cherry Streets) was Georgina Stanley Riches, who served from 1887 to 1912. At one time the school enrolled 269 students. In 1974, Sackville Street School closed and the building became home to both Inglenook Community High School and an aboriginal learning centre, which soon moved out. The school is said to be haunted.
