The Casino de Mont-Tremblant was inaugurated on June 24, 2009. The Casino du Lac-Leamy was the first of Québec's casinos to be built from the ground up.
In 1994, the Casino de Charlevoix opened its doors in what was once the Manoir Richelieu's summer playhouse located at Pointe-au-Pic. The Casino de Montréal was inaugurated on October 9, 1993, and is located in the former French Pavilion ( Pavillon de la France) of the 1967 World Exposition. The creation and management of these government-run casinos was entrusted to Loto-Québec, which subsequently created three subsidiaries: the Société des casinos du Québec Inc., given the responsibility of building the casinos and overseeing their operation, Resto-Casino Inc., which operates the restaurants and bars at the three casinos, and Casiloc Inc., which is in charge of acquiring, building and overseeing casino facilities. In December 1992, the Quebec cabinet approved and authorized the construction of two government-run casinos: one on Île Notre-Dame, in Montreal, and the other at Pointe-au-Pic in the Charlevoix region. The Société des casinos du Québec oversees all four government-run casinos in the province of Québec: the Casino de Montréal, the Casino du Lac-Leamy, the Casino de Mont-Tremblant, and the Casino de Charlevoix. The Société des casinos du Québec is a subsidiary of Loto-Québec, a government of Québec corporation.
