[tor-relays] DMCA notices in Canada?

Hi, Have any other tor operator *in Canada* been targeted with DMCA takedown notices? We have received a bunch from our upstream provider and so far have refused legal responsability because (a) we're not in the US and (b) there's nothing to takedown, we're just a transit provider... But now our upstream is threatening us to completely disconnect us if we do not take action within 30 days. We're running a full exit node, so it's likely getting used by people for bittorrent downloads... Ideas? Suggestions? Legal support? United organised legal front?
