In Ontario, "Frozen Treat" and "Ice Cream", "Orange Juice" and "Orange Drink" are on shelves often right beside eachother with nearly identical packaging. I only noticed the latter when I saw one was significantly cheaper, at first thought it was pulp/no pulp.

Yup, exactly - which is what makes the regulated descriptors (eg "juice") so important!

Do you have an encyclopedic knowledge of which terms are regulated and which ones aren't?

Don't you think it would cause more confusion if people expecting to buy a Jamaican beef patty instead have to buy a "Jamaican beef-inside-pastry product" ?

Do you have an encyclopedic knowledge of which professions are regulated and which aren't? If not, should we get rid of professional licensing?

This feels like a strawman given that they settled on "Jamaican patty", which is reasonably brief and certainly less confusing than the original term of just "beef patty".

The solution is to ensure all common terms people expect in a daily shopping are covered. Thus why "beef patty" was covered. Sounds like you agree with the government on this one. Not covering it would make it confusing for people who would then need to keep track of which common terms are covered and which are not. Its a bit silly at times but as you noted yourself the alternative is even worse.
