It would certainly be an acceptable thing to talk about. They are looking for women who are involved in outreach and who want to give back to their communities.

Well, it's been awhile aha. And I would like to extend a big Thank You to all the people who replied to this post :). I recently finished registering and I think I may have forgotten a few activities that I did while in High school. Should I email them about it, or is it really not that important due to the more relaxed feeling of Canadian sorority recruitment? I figured if all else fails, I could always talk about the missing activities during recruitment :)

If it was just a couple of activities, then I would just bring it up casually during recruitment. :)

I think you would be safe to wait until to recruitment to mention them, but if it's gonna drive you crazy, it's not too weird to email them :)
