It depends on how they choose to apply the term to foods/beverages in Canada. For foods and beverages, even something in concentration, though natural, may not qualify because you wouldn't be able to naturally harvest the substance in concentrated form. So even though you may not have altered the purity or changed the chemical or molecular make up of the natural substance, you may still not be allowed to add "all natural" to the label. Another possibility I think is if you add citric acid (or any other natural compound) to enhance the flavor, so it wasn't all obtained from a freshly squeezed fruit for example, that might be it also. Those rules don't necessarily have to comply with the dictionary definition of natural, they can dictate the terms of it's use based on how they think the average consumer will interpret the meaning. According to Jerry it was frustrating how silly it seemed, but I guess people will just have to read the label and see for themselves just how basic/simple the ingredients are. I think most people do read labels today verses years ago when most didn't. Just delays, all will be resolved very soon I'm sure.
