Canadian merchandise can be labelled Made in Canada if more than 50% of VALUE is created in Canada.
That means, if you buy apple concentrate in China for 20 cents a pound and make apple juice out of it you can label it made in canada, because out of $1.59 for a liter of juice apple concentrate is worth 10 cents. Perfectly legal
Surprising, but not a shock. There are just a heck of a lot of people in business and government who do not want consumers to have knowledge of where the products they buy were actually produced.
And, if sellers thought giving consumers that knowledge would be a positive reflection on their products, they'd put true country of origin information in a prominent place on labels. The opposite is also true, obviously.
