I can say that in areas where the RCMP is a member of the multi-agency security committee at airports, information is shared in terms of security threats and risks at airports. In cases where a threat is identified, it could be through the police of jurisdiction or it could be through the airport authority. It may even be through the aftercare process that Transport Canada has put in place. That information would go back to Transport Canada to do a reassessment and they may engage the RCMP to do a more in-depth law enforcement record check.
