Ontario's doctors say they'll introduce some of the most aggressive measures to fight obesity ever proposed in Canada today.

Last month, Ontario Medical Association president Doctor Doug Weir called on the government and the food service industry to partner with doctors in fighting the province's obesity epidemic.

Weir called for restaurants and school cafeterias to post caloric and sodium content on their menus to give consumers the information they need to make healthier choices.

The O-M-A says 75 per cent of obese Ontario children become obese adults, and estimates obesity costs the province at least 2.2 billion dollars annually.
