The school is named after the priest Francis Libermann, a French Jewish convert to Roman Catholicism in the 19th century and the "Second Founder" of the Congregation of the Holy Spirit.

Because this design accommodated a more petite student body, the school had to deal with perpetual overcrowding, requiring the construction of additions and alterations.

To resolve these issues, staff members devised a schedule involving required study halls for students with spare periods and separated up and down staircases.

[3][4] The overcrowding resulted in the MSSB establishing two new schools in the northern Scarborough area in 1985: Mary Ward in Steeles/Willowdale using two campuses and Mother Teresa in Malvern.

The school is surrounded by the Brimley Woods forest to the north, Royal Crown Academic School (Formerly Charles O' Bick Police Academy), a fire hall to the west, a ravine to the east, and an arterial road, Finch Avenue East to the south.

Students will not go an entire year without having math and obtain significantly higher marks in university prep classes[7] on average.

Libermann is host to elite academic students that benefit from being able to do year-long class projects to win awards.
