Primarily operating in Quebec, Réno-Dépôt was a warehouse-styled format with a focus on discounted renovation and household hardware products.

In May 1992, Groupe Val Royal with its partner Aikenhead's, both owned by the Molson Companies (the former in part, the latter as a subsidiary), announced the creation of warehouse stores under the name of Réno-Dépôt inspired straight from the Home Depot chain in the United States.

In 1999, Réno-Dépôt opened a location in LaSalle and, the following year, entered the Ontario market under the English-language banner The Building Box.

[4] The purchase was part of a plan to establish more "big box" stores to accompany its smaller specialty outlets and compete with the U.S.-based chain The Home Depot.

[5] In 2013, in the wake of cuts across the company, the Réno-Dépôt chain was re-positioned as a discount wholesale-focused banner with a reduced product selection.
