McGill Desautels has a strong international focus, in all majors. It is also their most selective faculty.
My son is a McGill alumnus. He is an American. He found the freedom that McGill, and all Canadian universities, offer just what he was looking for. With that independence comes the responsibility to be self-directed and motivated.
Social life is what you make it. Students join clubs, intramurals etc. There is limited Greek life if that is your thing. Athletics exist but are not that popular, not even hockey.
