Le Château Inc. (French pronunciation: [lə ʃato]) is a fashion company, currently owned by Suzy's Inc. The chain was founded in 1959 in Montreal, Quebec, Canada, and designed, imported, and retailed women's and men's apparel, accessories, and footwear. In 2015, the company generated sales of about CA$237 million. The company operates in 57 Suzy Shier stores, before bankruptcy, they sold directly to customers from 123 retail stores in Canada and 5 in the UAE and Saudi Arabia.

Founded by Herschel Segal in 1959, as "Le Chateau Men's Wear", it began as a menswear store in downtown Montreal Victoria Square. Segal gave his store a French name because of the budding francophone feelings occurring in Quebec. At first, Le Château was not a "fashion-forward" store, as it would later become, as Segal sold overstock from his father's old store. In 2003, Segal described his early customers as "old ... blue-haired ladies." Le Château did well at first, and three more stores were opened. However, by the early 1960s, the company was close to bankruptcy, and all but the original store were closed.

In 1962, Le Château added women's clothing, shortened the name to "Le Château", and switched to selling imported European fashions. The store imported from Carnaby Street in London, a fashion centre at the time, as well as other imports such as French suits and Italian turtlenecks. This worked well, and within a few years, Le Château completely phased out the original traditional clothing style to concentrate on selling fashionable imports to youths. Segal claims that Le Château was the first to introduce bell bottoms to Canada, and had the latest European fashion before it even arrived in New York City. Le Château played an integral yet little known role in John Lennon and Yoko Ono's 1969 Montreal bed-in, providing the signature velour jumpsuits worn by the pair. By 1972, the chain grew to 10 stores, and by the end of the decade Le Château had over 50 stores across Canada. By this time, Le Château had shifted to selling mainstream fashion instead of the latest imports from Europe.

In December 1983, Le Château had its initial public offering on the Toronto Stock Exchange (TSX). It raised $7.3 million. By the early 1990s, Le Château had 160 stores and had switched to doing most of its design and manufacturing itself. In the early 1990s, there was a prolonged recession in Canada which hurt most businesses in the clothing industry.

In the mid-90s, Le Château experimented briefly with Goth styled clothing, and in 1997, it launched a short-lived adolescent girls brand "Jr. Girls."

By 1999, the company's stock fell to an eight-year low. This led to a management shakeup, store redesign, changes to the merchandise, and according to Le Château, a concerted effort to improve its quality and image.

In 2003, Segal acknowledged the "disposable fashion" stereotype, and said the company "forgot about" the product. "We might have been sloppy," he said. "But now we're putting in more money and time. We have an inspection system and a young lady who's a grad of a textile school. We never had that before." Since then, Le Château has been trying to build up its brand image and shed the image that its clothes are "only for wearing to nightclubs," a view that still persists. That year, it released a collection based on the 1960s-set Renée Zellweger movie, Down with Love and was the exclusive supplier of clothing to Canadian Idol contestants.

With many US retailers expanding into Canada, including competitor Express, and fast fashion stores such as H&M and Zara gaining market share, Le Château relaunched their brand in 2012. The company went from apparel for young shoppers to "new concept" stores carrying better quality, grown-up clothes at various price points. The rebranding was complete with a new logo and new white, sterile, more upscale stores, with nickel fixtures and glass shelving. Known for their tailored and form-fitting clothes, it sells formal wear, casual wear, evening wear, and footwear. At this point, Le Chateau had over 240 stores in Canada. While Le Château is publicly traded, the company is tightly held with 67% of shares owned by Silverstone, the company's board, executives, and two institutional investors. In addition, the shares have less than 2% of voting rights. The CEO at the time was Segal's wife, Jane Silverstone-Segal, following her promotion during the 2008 restructuring.
