Final answer:
The proposed Canadian measure to impose stricter controls on imported baby formula would likely involve several World Trade Organization (WTO) rules, including non-discrimination and scientific basis for regulations. Canada has the right to set stricter controls as long as these rules are followed.
Step-by-step explanation:
The proposed Canadian measure to impose stricter controls on imported baby formula would likely involve several World Trade Organization (WTO) rules. One important rule that would come into play is the principle of non-discrimination. According to the WTO, countries should not unjustifiably discriminate between countries where identical or similar conditions prevail. This means that if Canada imposes stricter controls on imported baby formula, it should apply these controls equally to all countries, without singling out specific countries for stricter regulations.
Another relevant WTO rule is the requirement that regulations must be based on science. This means that any stricter controls on imported baby formula imposed by Canada should be supported by scientific evidence that demonstrates the need for these controls.
Furthermore, the WTO allows countries to set their own standards, as long as they are not arbitrarily or unjustifiably discriminatory. So, Canada has the right to set stricter controls on imported baby formula as long as the basis for these controls is scientific and the same standards apply to both domestic and imported products.
