The Atlantic Universities Athletics Association was founded in 1974, with the merging of the Atlantic Intercollegiate Athletic Association and the Atlantic Women's Intercollegiate Athletic Association. Prior to the acceptance of Memorial University of Newfoundland, the AIAA, which dates back to the late 19th century, was known as the Maritime Intercollegiate Athletic Association. The AUAA changed its name to Atlantic University Sport (AUS) in 1999.
Canadian athletic facilities are often listed by their "maximum capacity", which is often an estimate of their largest recorded crowd in the facility. These maximum capacities can and often do include standing room patrons and attendees seated on grass surrounding a playing field. Seated Capacity is the actual number of permanent seats, be they grandstands or permanently in use bleachers. This is why you will sometimes see larger capacities listed for these sites when searching for them on line. When capacity numbers have mismatched on source sites, unless the larger capacity could be confirmed as a seated capacity, the smaller capacity number has been listed here.
Please update with verified "seated capacities" only when the institutions release more accurate official seated capacities.
Moncton has built a new 10,000-seat on-campus stadium designed in part to host football. It is unclear if the University will be adding the sport.
(*Saint Mary's Huskies Stadium has a listed capacity of 9000, but the accuracy of this as a fixed seated capacity is questionable. Articles have suggested that permanent seating is only 4000, but note that temporary seating can get the capacity up to 9-11,000. Additionally, attendees often sit on the grass and the grassy areas are likely included in this official capacity of 9000. Seated capacity would only refer to the grandstands and any permanent seats or bleachers.)
