Zellers was a Canadian chain discount department retailer that was based in Brampton, Ontario. It was founded in 1931 and was acquired by Hudson's Bay Company (HBC) in 1978. A series of acquisitions and expansions allowed Zellers to reach its peak in the 1990s, with 350 stores across the country in 1999. However, fierce competition by Walmart Canada and an inability to adjust to the increasingly volatile retailing industry resulted in Zellers losing significant ground in the 2000s. At the same time, HBC's new owner NRDC Equity Partners was focusing on bolstering and re-positioning Zellers' sister chain, The Bay (since renamed Hudson's Bay), with an upscale and fashion-oriented direction, and saw Zellers as a detriment to the turnaround.
