places your orders for  purchase of Canadian Jr Mining shares.  The US broker directs theCanadian broker  like a TD or some other Canadian brokerSinc to place your order. The shares are in the street name so they reside with the Canadian broker who can  toss 100 shares at the bid price all day long......seems like 500's here.  They been getting away with it for years.  A few years ago the Schwab customer service rep told me TD was one of the Co's that did their Canadian mining trades.
