Most real food products (fruit, vegetables, meat, dairy, bread, etc) in Canada don't have any tax on them.
Many of the processed foods like soda and chips do.
There are gray areas, like many granola bars having tas on them because of their similarity to candy bars.
There's also some arbitrariness, such as an uncooked whole chicken being tax exempt, but a cooked one from the same grocer's deli may be taxed fully as if it was a restaurant meao.
It's certainly possible that a box of oreos is processed enough to be hit with the 15%.
But if you actually bought the raw ingredients to cook your own homemade cookies - flour, sugar, eggs, vanilla extract, chocolate chips, etc, the actual deconstructed component ingredients are all tax free.
