I think that you got onto something useful when you said that you had been conducting studies to see whether there might be a form of unconscious racism or discrimination, because I have experienced it. Recently, there were unilingual English positions to be filled at IRCC offices in Montreal. I've already argued on behalf of allowing a lawyer to plead in French before the Immigration and Refugee Board of Canada. Nothing unconscious about that.
So it's essential to look into that to see whether there is some form of francophobia or something else that's not working at IRCC.
