In both cases, the proposals are intended to grant Canada its request to have the right to designate up to 6% of tariff lines as sensitive products. That is the basic point. In exchange, Canada would have to accept the different ways of structuring its increase in quota.
There are two different ways of calculating the quota expansion. It could be by calculating only the additional 2% of tariff lines, because the others are agreed upon under the principle of 4% of tariff lines, or by calculating a tariff quota expansion that applies to the entire 6% of the tariff lines. Therefore, those are the two possibilities intended to achieve the same objective: how to calculate the tariff quota expansion that would be granted to other countries in compensation for having granted Canada an increase in tariff lines that could be designated as sensitive products.
