Only applicants who are identified for interviews will be contacted in the weeks following the applications closing.

All qualified candidates are encouraged to apply. However, those legally able to work in Canada and at McMaster University will be given priority. McMaster is strongly committed to employment equity within its community, and to recruiting a diverse faculty and staff. Accordingly, the University especially encourages applications from women, members of visible minorities, Aboriginal persons, members of sexual minorities, and persons with disabilities.  

Please note: those who have not, at the time of application, been assigned 260 hours of Teaching Assistantship(s) will be given priority consideration. Those who have already been assigned 260 hours of Teaching Assistantship(s) at the time of application may nevertheless apply. Once the preference note above has been taken into account, applicants who have already been assigned 260 hours of Teaching Assistantship(s) may be offered the position, but in order to accept such offer they must obtain and submit written approval to work such additional hours pursuant to section 2.4.3 of the SGS calendar in the case of graduate student applicants, and from the appropriate Department Chair in the case of undergraduate applicants.
