I'd like to comment with respect to labelling and how you tell juice from sugar.
This is not something the CMA has done, but it's from my old job at the Heart and Stroke Foundation of Canada. You'll note that when you go into a grocery store now, you see the health check symbol. One of the things the health check symbol does is it looks at claims like low fat when it doesn't necessarily equal low sugar. We did some market research indicating that when moms go down the grocery aisles, they want to see a health check on the food so that they can say no to the Froot Loops, no to the Cocoa Puffs, and say to their kids, “You can have anything with a check mark on it.”
My point is that you don't necessarily have to look to government regulation in all cases. You can also look to the not-for-profit sector to maybe help out in determining what's a sugar versus a pure juice alternative.
