Hudson's Bay Co, forced to close its doors as large chain such as Costco, Loblaw, Canadian Tire and Wal-Mart continue to stay open during a pandemic retail lockdown, on Thursday filed for a judicial review by Ontario's Superior Court of Justice of the current regulations governing non-essential retail in Toronto and Peel. The retailer, Canada's oldest, is asking for a declaration that the exclusion of department stores and department store-type retailers from the list of exempted retailers on a Nov. 22 lockdown order "irrational, arbitrary, and leads to results incompatible with the legislative scheme." It is also asking for a declaration that the lockdown regulations are ultra vires.
