The issue you raise, of course, is of concern to lots of organizations. As I recall, we did some work on this a couple of years ago, and I think the figures for the federal public service weren't as robust; they were low, as in the private sector they were low.
One of the things to do I think in terms of that is to know your market, segment your market. It's like Marketing 101 for people. So if you understand you want to recruit more people with racial backgrounds and more visible minorities, and you're working in Montreal, you know the largest immigrant population in Montreal is from Haiti, and then you would know that population; you would target that population. I would target the population and I would speak in a language, culturally and literally, that they understand. So I would appeal to what appeals to them.
I think the federal government has tried very hard, from what I can see, in trying to remove those barriers, but there is something definitely going on.
