The Act to improve the legal situation of animals, unanimously adopted in 2015, is the last major legislative evolution in Quebec animal law. This law changes the legal status of animals, from property to sentient beings, and introduces a stricter legal framework for the welfare and safety of domestic animals. Despite these legal changes, many animals are still denied their sensibilities and their biological needs, especially on farms, creating situations that are more than absurd: a pet pig must be protected from excessive heat under penalty provided by law while on the farm, pigs die of heat, literally, during heat waves. How to explain such a shift? Why are sentient animals not all protected in the same way? The interest-convergence theory provides that a social change in favour of a minority group can only take place when the interests of the majority and those of the minority “converge” similarly toward that change. Interest-convergence is a plausible explanation for this legal gap. This article focuses on the context that led to the adoption of the Act to improve the legal situation of animals. The content analysis carried out on parliamentary proceedings shows that besides a concern for the animal, economic and social reasons are also at the source of the new legislation, and that economic interests explain its limits, thus confirming the presence of the phenomenon of interest’s convergence during its creation.
