Never been huge on Hudson's Bay, but honestly this can be owed to improper regulation of online shopping. The fact that the government hasn't done more to protect Canadian businesses from online competitors, namely Amazon, is absurd, especially with the ridiculously wasteful practices Amazon has made an industry standard.
It's already a pain for malls and shopping outlets to find replacements for old Sears and Target/Zellers locations. This being added to the mix is going to deal a huge blow to malls where Hudson's Bay is seen as an anchor, and an equally large blow is going to be dealt to the social shopping experience.
Being from Edmonton, Kingsway Mall already comes to mind. When Sears closed, the space eventually became occupied by a Walmart, and it's worrisome to think of another heavily American retailer swooping in on where Hudson's Bay is currently, or it being the case that they demolish the entire section of the mall similar to what they did at Mill Woods Town Centre with the old Target/Zellers space.
