Ah, I see... So because this was an after hours trade, when these folks outside of Canada were buying, they couldn't go through the TSX, which would often be the case during regular hours; not always, but often (as is the case for me - hadn't ever tried to trade after hours, ;-)).
Yep. That makes sense. Most of the time, we simply don't know how many shares are bought/sold outside of Canada.
Still, it's awfully nice to see that big after hours volume (from whereever it might come, ;-)).
