Here is where I am at.... Trading history for the debentures.
Scotia Capital is handling the transactions, serving as a proxy. I am trying to figure out who might be using them as a proxy. I know that FFH used to own a large stake of Scotia Bank who owns Scotia Capital (SC). SC is an investment bank, and the transactions show that they are buying and selling the debenture shares simultaneously.
This looks like someone covering their tracks. Still researching connections.
