The Michael G. DeGroote School of Medicine is on the main campus as well as in two regional campuses at St. Catharines and Kitchener. The Waterloo Regional Campus is in downtown Kitchener, where it shares facilities with the Health Sciences Campus of the University of Waterloo. The campus in St. Catharines is at Brock University's Niagara Health and Bioscience Research Complex. Approximately 30 medical students in each year of the program attend each campus. Those who apply to McMaster's School of Medicine are asked to rank their site choice (Hamilton, Niagara Region, Waterloo Region) from first to third, or no preference. Offers of admission to the medical school are made from a rank list irrespective of geographical preference. Subsequent to an applicant's acceptance, registrants to the class are placed based on their preference and geographical background. The offers given out by McMaster are bound to the assigned site.
