It has departments for VMBO, HAVO, athenaeum, and gymnasium.

The school offers "bridging" for foreign students who enter without fluency in Dutch.

The school is named after the Saint Peter Canisius and is the legal successor to a former Jesuit boarding school of the same name.

Besides the main location there are two branches: De Goffert for pre-vocational secondary including LWOO, and Akkerlaan the international bridging school.

In 2013 enrollment at Canisius' three locations was: 1,441 at Berg and Dalseweg, 543 at Goffert, and 51 at Akkerlaan / ISK.
