Again, there are a number of ways that may occur. If there is a suspicion that an individual is becoming radicalized, is radicalized, we go through our internal security process where we would try to assess that risk in a timely manner. Transport Canada would be involved in terms of re-evaluating the security clearance that they've provided. In some cases that may come directly from Transport Canada to the RCMP and we would do a new investigation around whether there's new information that has come to the attention of police from the time the initial clearance was issued to the time that a new suspicion or new concern has surfaced.
There are processes on an ongoing basis to monitor those who have Transport Canada security clearance, to initiate a review of those for cause.
