Nutrition labelling requirements were put into effect a number of years ago in Canada. Every food and beverage item for sale must contain a detailed list of ingredients, as well as nutrients like sodium, fat and sugar. We can make our choices based on the label. Tobacco, by law, also must contain label warnings on the package about the health effects.
