Hudson’s Bay Co. says Ontario’s regulations forcing some retailers to close while others with similar merchandise remain open are “irrational and arbitrary.”Jonathan Lisus told a video hearing with the Ontario Superior Court of Justice today that the province’s regulations make no “rational distinction” between the department store and some of the big box and discount retailers which are allowed to remain open.He says there are hundreds of chain retail stores open for business that look “just like HBC” with the sole distinction that they sell an unspecified, undefined amount of “so called” groceries.
