Western’s teams have amassed a total of over 400 OUA/OWIAA/O-QAA championships over the school’s years in senior intercollegiate competition. The first of those championships came in 1926-27, when the men’s basketball team gave purple and white fans their first taste of victory in senior leagues. Since then, Western’s teams have been outright dominant in many sports, collecting a total of 30 OUA football championships, 28 basketball championships (both men and women), 16 volleyball and soccer titles, and many more. For a complete list of Western’s OUA Championships and All-Stars click here.
Unfortunately, excluded from the list below (for now) are the championships won by Western’s women in WIAU play before the organization became part of the OWIAA in 1971, as a complete list is not readily available online or in the museum’s archives. During the span that the WIAU ran, from 1921 until 1971, the Mustangs collected their fair share of basketball Bronze Baby’s and volleyball championships, along with a number of other titles. If those championships were to be included on this list, then Western’s championship total would run much higher than 418. Hopefully, those titles will be added soon.
