This is the 1964-65 Women's Intercollegiate Athletic Union season.

The Toronto Varsity Blues won the championship with a 4-0-1 record.

The season appears to have consisted of a two weekend tournament held February 20, 26 and 27, 1965 also involving the McGill Martlets, the Guelph Gryphons, Queen's Golden Gaels, McMaster Marauders, and Western Ontario Mustangs.

note: The Guelph Gryphons make their first appearance under this name as Ontario Agricultural College was renamed Guelph University in 1964.
