There are no additional costs for the security lapses. There were additional security measures taken in that building that are consistent with the evolving threat. If we go back to when this building was designed in the late 1990s, subsequent to the contracting for that facility and the commissioning of that facility as a NORAD air defence centre, the threat has changed. The threat to North America, the threat that NORAD is responding to, has changed, and that has required some additional measures to be taken from an operational perspective, not related to the security of the building.
Those changes in the operational posture of that building, as a result of the post-9/11 environment that we're working in, warranted a number of both physical and technical means to be put in place to ensure the continued integrity of that facility. Those means were put in place before the building was commissioned for use by NORAD and the Canadian Air Defence Sector, and they continue to be in place and monitored today.
