The facts in Commission des droits de la personne et des droits de la jeunesse c Bombardier inc (Bombardier Aerospace Training Center) give us the opportunity to address the required link between the adverse treatment and the prohibited ground of discrimination under the Quebec Charter. In this text, the author argues, firstly, that the link must be established between the prohibited ground of discrimination and exclusion suffered, in both direct and indirect discrimination. Then, he questions the nature of the link. He specifies that the prohibited ground should not necessarily be the sole or the principal ground of the exclusion, but rather one of them. Given these elements, the author then offers a unified methodology to provide guidance to courts when they analyze the prima facie evidence of discrimination. Thus, in the second step of the section 10 test, the plaintiff has the burden to establish, in both direct and indirect discrimination, that the prohibited ground of discrimination was one of the bases of the exclusion.
