Merchandise Building, Residential loft complex in Church-Yonge Corridor, Toronto, Canada.

Merchandise Building is a residential loft complex in Toronto's Church-Yonge Corridor, stretched across multiple floors with a steel frame and large windows. The building holds retail spaces at street level, a rooftop pool, and an indoor basketball court for residents.

The oldest section is a six-storey manufactory built in 1910 on Dalhousie Street for Simpson's delivery business; the Robert Simpson Co. Ltd. Mail-Order Building followed on Mutual Street in 1914. Expansion between 1931 and 1949 tripled its size while keeping the original design by architect Max Dunning of Burke, Horwood and White. Sears Canada used it as a warehouse until the 1990s, then sold it for loft conversion, completed in the late 1990s.

The name comes from Simpson's mail-order merchandise handled here; the 1914 wing was the Robert Simpson Co. Ltd. Mail-Order Building. Residents pass a four-storey interior lobby and an indoor half-basketball court, and the ground floor holds a supermarket. The conversion won a commendation from Heritage Toronto and an "A" from Toronto Star architecture writer Christopher Hume.

The location is easy to find and offers amenities within the building for recreation and shopping. Keep in mind this is a private residential complex, so access to public areas is limited.

The 1914 mail-order block was built with a steel frame, reinforced fire-proof concrete and a 40,000-gallon rooftop water tower. During the 1990s conversion a discarded cigarette butt set a three-alarm fire in an old freight elevator shaft; the debris burned for hours but the structure held, as its designers intended.
