We used to have alot more sororities at U of T, i think there were 12-15 but alot of them closed when the university bought out the land that the sorority (and frat) houses were built on to build a new (2nd largest in Canada) library. They closed back in the 50's i think. we also used to be recognized by the university back then, but due to one of the sororities not allowing an african american woman to join, they disaffiliated with us.
i know that we definitely had Delta Gamma, Alpha Phi now lives in their old house though. i think we also had Kappa Alpha Theta, but i'm not sure.
