The challenge your question poses is that the bar association advocates on behalf of its members—it's a voluntary organization—as well as for the proper administration of justice. Our mandate doesn't include policing lawyers. That's the mandate of the law society of each province.
Now the problem with unlicensed immigration consultants is.... With CSIC, our issue isn't really that CSIC doesn't have the mandate to do it, but that there seems to be some issue as to the federal government funding it properly so that it is able to enforce its disciplinary mandate against its own members.
Unlicensed immigration consultants exist outside of Canada or inside of Canada. Of the ones who are inside Canada, there needs to be more enforcement by the players in Immigration, including the department, the Canada Border Services Agency, and more use by the RCMP of investigations to bring these people to justice, where they've acted without proper authority.
