The tariffs exist to protect the supply management system.

No tariffs = disappearance of supply management overnight.

CETA only slightly increased the amount of cheese that can be imported duty/tariff free.

It’s by no means a free-for-all with EU cheese. I wish it were.

Purchasers are not purchasing European product _despite not having reached regulated limits_.

Regulation was relaxed, and the purchasers are not availing themselves of the opportunity to purchase European goods.

It doesn't matter that it's not a free for all, because the limits have not been hit.
