There's a good read here about the change of the Hudson's Bay logo. Interestingly, it mentions that the generic and corporate HBC logo would be all but forgotten, but it can be found on the north east end of the Bayshore parking garage, which I find to be a very odd location and also a very bizarre decision in general. Especially when the rebrand of the last few years (Bayshore being the first Bay location in Ottawa to rebrand), I don't know why they'd stick the corporate HBC logo on there as well.
