Hrmm as bad as it is, given that the short interest is only 25 million shares or so out some 470M shares, and that I don't imagine that they're all naked shorts, it probably won't be the deciding factor.
Plus with IIROC reporting a TSX trade failure rate of 0.22%, it's probably not a big deal.
What I'm somewhat curious to know is how they handle the dividend payments/charges with naked shorts. Whether you bought it or sold it.... Actually a share dividend would be an even more interesting scenario.
I guess the institution eats the cost/takes the cash for the buyer/seller?
