CANADA - McDonald's to label food - Calories, Carbs, Fat, Protein Etc. - Fast-food chains opt for standard labels: "Health Canada estimates the economic cost of poor nutrition is $6.3 billion annually, including direct health-care costs of $1.8 billion."

Previously, nutrition labelling was voluntary and wasn't standardized, making comparisons between products more difficult.

Ottawa announced the mandatory nutrition-labelling program in January 2003, but gave food companies until the end of this year to make the changes.
