Interesting tidbit: Chi O was indeed in Canada, but way back in 1899-1900 at Hellmuth Women's College in London, Ontario. It is Chi O's old Phi chapter.

I don't think Hellmuth was ever affiliated with Western. The women's college affiliated with the university is Brescia and it is Roman Catholic. Hellmuth was probably Anglican.
