Hi Trevor,
I live in Thunder Bay while I am not away at school, and I can tell you there aren’t any secular groups that I am aware of in Thunder Bay, nevermind at Lakehead. Here is a list of all currently registered groups at Lakehead: http://www.lusu.ca/thunderbay/club-list/
I took a look through again to be sure, but there doesn’t appear to be a secular club. There is of course a Lakehead University Christian Fellowship club available, should you so choose.
And to answer your question, CFI is definitely not just an American organization. I am a member of CFI Canada - which is headquartered in Toronto - but has many branches nationwide (none in TBay though, sadly): http://www.cficanada.ca/about
If you would like to start a CFI affiliated club at Lakehead, CFI can help answer some questions on how to get started here: http://www.centerforinquiry.net/oncampus/faq/
If you don’t want it to be CFI affiliated, that FAQ is useful on how to start a college club anyway. Either way, you will need to follow Lakehead’s rules on creating a club:

Thunder Bay is a bit remote (in location and otherwise), and this is one of the obvious examples of it. Even away at school in Toronto there is no secular club at my college. I’ve been considering starting one, but I am wondering if it would be worth it with CFI headquarters being (technically, anyway) in the same city.
Anyway, good luck with starting your club if you choose to pursue it. I would definitely encourage it, there is a huge lack of secular associations in Thunder Bay. It’s too bad it’s closed to just students, I know several people who would be interested in joining (including myself).
Hope this was useful to you!
