I vaguely remember posting this on another thread, but I'll do it again.
Kappa Alpha Theta is international, and has been since 1887, when her Sigma chapter was established at the University of Toronto. Theta's other Canadian chapters were established at the University of British Columbia, University of Alberta, University of Guelph, University of Western Ontario, and McGill University.
The Alberta, UWO, and McGill chapters are still in operation, although the other three have been disestablished.
