There are two dimensions to my response. One is that in addition to the on-call availability of being able to reach out through the telephone system to one of our operational response staff, we also have available the Government Operations Centre, also part of Public Safety, which is staffed 24 hours a day, seven days a week. So in the event that there was ever a disruption in our ability to reach out to our on-call person, they have the immediate availability of someone 24-7 in the Government Operations Centre.
