While the university maintains bilingualism as an official policy, students need not be bilingual. Instead, most courses and programs are offered in both languages. As of September 2011, the percentage of students who used French as their primary language of education was at 31.1 percent, while the number of students which use English as their primary language for education was 68.7 percent. As of March 2009, 68.6 percent of professors in bilingual positions were considered to be actively bilingual, while bilingual staff comprised 91.5 percent.
