Loto-Québec has quietly decided to keep the Casino du Lac-Leamy open 24 hours a day, seven days a week to "meet the needs of its clientele" and compete with other gambling outlets. Jean-Pierre Roy, a spokesman for the provincial agency that operates casinos in Gatineau, Montreal and Charlevoix, near Quebec City, said yesterday that, after 12 years and 40 million visitors, it was time to open Casino du Lac Leamy around the clock.
