After much searching, I came to the Ottawa Medieval Sword Guild website. There, to my dismay, I found they were not accepting members.

Does anyone know of any other good longsword groups in the Ottawa or Hull region? (or any longsword groups in the region for that matter?)

Actually, yes. There's Les Maitres D'armes - of which I am a founding member and instructor. Our session just ended for spring, and we resume in the fall with classes in Hull and in conjunction with the city of Ottawa at the Richelieu-Vanier Centre. We're bilingual and semi-competent :p, and practice mainly longsword, dagger and wrestling according to Fiore, although our credo is basically "it's all longsword..." PM me for more info, if you like.

Also, Bill Fedun used to give classes out of Algonquin College, but I'm not sure he's still active. From what I've heard, it's not historical, but rather his own system which is historically inspired. That's just hearsay, though.

Not to beat my own drum (but I will, and shamelessly at that) we've been making some good headway in the region. The medieval studies program student's association at the University of Ottawa invites us regularly to give demonstrations and talks, we will be doing some demos for a program with the Ottawa public library, we help organise the yearly medieval festival in Hull (and though we try to make it more historical, people like gargoyles and face painting, what can I say?!) as well as give demos there. We've been working hard towards gaining visibility and credibility, and we're right about there, I'd say. That's enough drum beating for now, I'd say. :D
