Have a look at some post by JID ( a "whale" trader/speculator, at least relative to a minnow like me) about the cons of having your shares listed on the TSX using Oz brokers - I think they are on the RSG thread - you may have to research back over the last 9-12 months, and I recall he had a discussion with poster fbx258 about it.
