I did look generally at visible minority status in my research, and yes, even after controlling for education and all sorts of different characteristics, there does seem to be a disadvantage for visible minorities in the labour market. As Kelly pointed out, it's often entangled in other things. There are a lot of different factors: region of origin, quality of education, or perceived quality of education from region of origin. There's a very complex thing that goes on, I think, and it's difficult to disentangle, but yes, I have found evidence for that, though.
