Completed in 1969, this building housed a variety of staff departments and was located next to Stirling Hall on ¾ÅÐãÖ±²¥ Crescent, now called Bader Lane.
It was one of three small buildings at ¾ÅÐãÖ±²¥ named after area waterways - the other two being the Cataraqui Building and the Rideau Building, constructed at about the same time. The building was demolished in 2000 to make way for the construction of Chernoff Hall, the home of the Department of Chemistry.
