On November 2, 2006, the Quebec Cabinet authorized Loto-Québec to open four gaming halls in Québec, to be known Ludoplexes, in Montreal, Quebec City, Trois-Rivières and Mont-Tremblant. This authorization allowed Loto-Québec to reach a new stage in its 2004 development plan. The plan has, among other features, a reduction in the number of video lottery terminals (VLTs) intended to tighten access. In point of fact, the number of VLTs dropped 20%, from 14,301 in 2006 to 11,410 in 2009 while the number of VLT locations went from 3663 to 2327 – a drop of 36%. The 11,410 video lottery terminals generate sales of $670 million. Quebec public health authorities (Serge Chevalier, sociologist) estimates that the majority of revenues from these terminals come from problem gamblers, a conclusion that Loto-Québec contests.
