As it currently stands and as it would continue under this amendment, during the interview, a foreign national can already have someone present, counsel or another representative. The only matter is, however, that the representative will be asked to not participate in the interview process. Again, in cases where the CSIS interview is requested, it is in order to provide advice to an IRPA officer, whether it be a CBSA or a CIC officer, to make a determination afterwards.
On November 26th, 2012. See this statement in context.
