The Commissaire à la déontologie policière and the Tribunal administratif de déontologie policière are two separate and independent bodies. The Commissaire à la déontologie policière is mandated to receive and process complaints against police officers or other peace officers subject to the Code of Ethics of Quebec Police Officers. It can hold conciliation meetings, conduct investigations and plead before the Tribunal administratif de déontologie policière.

The Tribunal administratif de déontologie policière is an administrative tribunal which, after hearing the evidence, makes a decision as to whether or not a police officer or other peace officer has violated the Code of Ethics of Quebec Police Officers. If so, the Tribunal administratif de déontologie policière also decides on the sanction to be imposed.
