In 1897, the university had made all athletics, physical activity and sports under the jurisdiction of a central executive committee.

The name, the Marauders had been credited to Bill Cline, who on 26 November 1948, had his suggestion for the nickname of the university's men's basketball team published on the school's student newspaper, The Silhouette.

The Marauders football team on occasion used Ivor Wynne Stadium, the now-demolished home of the Hamilton Tiger-Cats.

The Marauders have won several championships since they began competitive play in their provincial conference, as well as within the national league they are in.
