This is and example of what the broadcast message would look like during the event. The format of the message has been modified to fit the scenario and the area it is occuring in.
"Attention, all citizens of Canada.
This is the emergency broadcast system. This is not a test.
The Emergency Broadcast System has been activated because of the mysterious conditions that have caused civilians to attack others in riotous mobs. At this time no information has been released regarding these mysterious conditions.
We shall bring you further information as soon as possible. Meanwhile, stay tuned to this wavelength, stay calm and stay in your own homes. Remember there is nothing to be gained by trying to get away. By leaving your homes you could be exposing yourselves to greater danger. If you leave, you may find yourself without food, without water, without accommodation and without protection.
Make your food stocks last: ration your supply, because it may have to last for days. If you have fresh food in the house, use this first to avoid wasting it.
We shall repeat this broadcast in two hours' time. Stay tuned to this "wavelength." '
