To the east of the casino is Leamy Lake (in French: Lac Leamy), from which it gets its name. This lake is home to a large fountain, whose jet is visible through much of the old Hull sector during the summer. The casino is built on a rocky precipice over what was once International Portland Cement Company quarry but is today Lac de la Carrière. In 2016, the casino provided the government with some CA$244,679,000 in profit, employed more than 1,400 people and attracted more than two and a half million visitors. It is operated by Société des casinos du Québec, a subsidiary of Loto-Québec. The Gatineau casino thus also serves the nearby city of Ottawa and Eastern Ontario. Ottawa, the larger city across the Ottawa River, was also planning to build a casino in the early 1990s, but these plans were blocked by the Government of Ontario. The casino was opened on March 24, 1996, in the former city of Hull, Quebec, the third of a group of casinos built by the provincial government to raise funds. The Casino du Lac-Leamy (formerly the Casino de Hull) is a government-run casino located in Gatineau, Quebec, Canada.
