It allows for different employers to be subject to the same conditions, so that it is not just the conscientious employers who are doing this, but that all employers are held to the same standard.
I think the other thing to be said is that if employers who are operating in a sort of open environment, where the majority of the population is racialized, have 80% of their population drawn from non-racialized cohorts, you have to reflect on that. You're losing opportunity to get access to very talented people, a very talented cohort that exists out there, who could contribute to your workplace.
