If the student has explored all other options and still wish to change supervisors, he or she should talk to the graduate program director. If the supervisor happens to be the graduate program director, the student should talk to the chair of the academic unit. If the student remains uncertain or dissatisfied, he or she should talk to the vice-dean graduate studies of his/her home faculty. Beyond that, the student can talk to the university ombudsperson. The student can request that the exchanges with any or all of these individuals (directors, vice-dean, ombudsperson) remain confidential.
