Guillaume Charbonneau, a fifth-year medical student at the Université de Montréal, believes that there is no better way of ensuring progress than by being committed, heart and soul, both socially and politically. As early as the first year of his studies, this young man gave concrete expression to his social commitment by working with a social and international action committee (CASI) with which, among other things, he organized integration activities for immigrants. He then departed for Lima, Peru, where he followed a training course in humanitarian assistance. On his return, he established and then held the position of bioethics manager on the campus and set out to heighten awareness of this discipline in the university community. At large these activities have led him to take a greater interest in the debate on the health system and he thus contributed to a written summary addressed to the Clair Commission and a memorandum presented to the Romanow Commission. A stream of political actions then followed. In turn administrator, vice-president and president of the Fédération des associations étudiantes en medicine du Québec, he further increased his participation on numerous committees with the Collège des médecins, his university’s faculty of medicine and the MSSS.
