History
Rossy S Inc.
The first all-dollar store was founded in Montreal in 1910 by Salim Rassy, a Lebanese immigrant, whose name became Rossy. His son George took over the retailer in 1937 and led the company until his death in 1973 when grandson Larry Rossy assumed leadership of it when it had 20 stores.

Dollarama
The discount retailer grew to 44 stores by 1992 which until then operated under the name Rossy S Inc.. That year, Larry Rossy opened the first Dollarama at the shopping centre "Les promenades du St-Laurent" in Matane. By the late 1990s, Dollarama had become by far the primary source of revenue for the Rossy family. As such, the Rossy S chain was discontinued by the turn of the new millennium, with all of its stores either closed or converted into Dollarama locations. After converting all the locations to the dollar store concept, Larry Rossy continued to open new stores reaching 1,000 stores in 2015. In November 2004, 80 percent of the chain was sold for $850 million US, to a private equity fund, Bain Capital, of Boston, Massachusetts.
