I think it's a great idea, except that in the federal government we have employment equity to a certain extent. Unless the provincial governments mandate some sort of reporting back from employers as to what steps they have taken to eliminate these barriers and what benchmarks are set up for them to reach a diverse workforce pool, these issues won't disappear, because once you see the person, the next level of stereotyping and perception starts to kick in.
So it's a great idea to begin with, but the federal government should work together with the provincial governments to bring about employment equity—not a quota system, but a proactive reporting back to the government on what steps employers are taking to make sure they are eliminating these barriers, whether of stereotyping or credential recognition or whatever may be the case.
