No, not specifically. I think one would find that there have been numbers of complaints filed at various human rights commissions, but as with other types of discrimination, such as sexual harassment and other things, when they're explicitly listed, they do not magically disappear from the society. Commissions use a combination of education, providing practical guidance to employers and others, and vindicating rights through individual cases to try to change the social norm. Over time, one hopes, you move the yardsticks that way.
Even going back to the Northwest Territories, I don't believe you'd find jurisdictions that have adopted this saying that it has removed the problem. They would all say that they now have a firm legislative tool as a basis for all of those other activities, and a way, through individual cases, of making clear what the state believes, and also, that there is a practical way for individuals experiencing discrimination to vindicate their rights. That's been the genius of human rights law—and human rights commissions—throughout its life in Canada.
