In 2011, the TPIR were replaced for cigarettes and little cigars with the Tobacco Products Labelling Regulations (Cigarettes and Little Cigars). These regulations introduced the third and current set of 16 warnings in Canada. Currently, cigarette and little cigar packages in Canada must bear new graphic warning messages that cover 75% of the front and back of the package. The interior of each package contains 1 of 8 updated health warning messages, all including the number for a national quitline. The side of the package now bears 1 of 4 simplified toxic emission statements. These labels were fully implemented on cigarette and little cigar packages by June 2012 (though the 2000 labels still appear on other tobacco products). Canada also prohibits terms such as "light" and "mild" from appearing on tobacco packaging. The current labels were based on extensive research and a long consultation process that sought to evaluate and improve upon the warnings introduced in 2000.
