...so I actually looked up both schools.
There is a Durham College in Canada.
There are two Bishop Colleges...one in Canada and one in Texas that is an HBCU (Historicall Black College & University).
However I know for sure that Gamma Sig has never had chapters in Canada. Also it should be noted that sometimes there are typos in these lists. We've had chapters at schools that no longer exsist for whatever reason or don't have the complete name. So "Durham College" could be ANYWHERE in America, LOL...
But to answer the question, NO Gamma Sig has never had chapters in Canada. Well I could have just put this one sentence down, couldn't I.
