Although some areas of consumer rights are addressed by the legitimate objective of preserving public health and preventing fraudulent practices, it is not clear to what extent consumers` right to information per se could be considered a legitimate aim. However, it could be argued that, in some cases, consumers must be informed of the procedures and origin of a product in the interest of environmental protection, which is one of the legitimate objectives. It is also possible that measures falling within the scope of the United Nations Guidelines on Consumer Protection (as extended in 1999) may be considered a legitimate objective, but there is still no case law that would confirm or refute it. While gatt was a set of rules agreed upon by nations, the WTO is an intergovernmental organization with its own headquarters and staff, and its scope includes both trade in goods and trade in services, as well as intellectual property rights. Although designed to serve multilateral agreements, plurilateral agreements have led to selective trade and fragmentation among members over several gatt rounds of negotiations (not limited to the Tokyo Round). WTO agreements are generally a multilateral GATT resolution mechanism.  Canada was a member of several multilateral trade groups operating in conjunction with gatt, including the Organisation for Economic Co-operation and Development (OECD), the Quadrilateral Group and the Cairns Fair Trade Group of Nations. Membership in these groups has allowed Canada to influence the direction of trade negotiations. The General Agreement on Tariffs and Trade (GATT) was the first multilateral free trade agreement. It first entered into force in 1948 as an agreement between 23 countries and remained in force until 1995, when its membership increased to 128 countries.
It has been replaced by the World Trade Organization. In the end, this resulted in an average reduction of 35 per cent in tariffs, excluding textiles, chemicals, steel and other sensitive products; plus a 15% to 18% reduction in tariffs on agricultural and food products. In addition, the negotiations on chemicals resulted in a provisional agreement on the abolition of the US selling price (PPP). It was a method of valuation of certain chemicals used by these countries to impose import duties, which gave domestic producers a much higher level of protection than specified in the Customs Code. The third provision was added in 1965 and was addressed to developing countries that have acceded to the GATT. Developed countries have agreed to abolish tariffs on imports from developing countries in order to stimulate these economies. Lower tariffs have also had benefits for developed countries. When the GATT increased the number of middle-class consumers in the world, there was an increase in demand for trade with developed countries […].
