A corner store owner in St. Thomas , Ontario, Canada holds a package of cigarettes on March 12, 2012. A trial got underway in Montreal Monday against three leading tobacco companies, seeking $27 billion from them for allegedly failing to adequately warn smokers of the dangers of cigarettes. Plaintiffs filed two separate class actions that were combined into what is Canada’s biggest-ever civilian lawsuit, against Imperial Tobacco Canada (a BAT subsidiary), JTI-Macdonald and Rothmans Benson & Hedges in the Superior Court of Quebec.
