That was a modification implemented following a review of the tariff structure of a certain sector of the customs tariff. That review was conducted by an independent agency of that time, the Tariff Commission. Other negotiations took place under article 28. For example, a few years ago, we significantly simplified the Customs Tariff. Rates were subsequently affected, but that was technical and quite insignificant.
The rules of that simplification proved to be very interesting for Canadian merchants. For the government, that exercise resulted in foregone revenue of $90 million. The trading partners saw that that was really profitable for them. The simplification of the Canadian tariff was viewed by Canadian businessmen as a positive measure. That process didn't take very long.
