Emergency Notification Methods
You may have an emergency official knocking at your door, providing evacuation instructions to you or instructions for boil water advisory. You may have Emergency services driving through your neighborhood, providing instructions over a loud speaker. Unique partnerships & cooperation with COGECO and Sarnia Lambton Radio stations provides the City of Sarnia (Sarnia Police Services) the ability to interrupt local programming to provide Emergency Notification to the public.

Municipal out door sirens are used to alert the public outdoors in certain areas south of Wellington St of Chemical releases or of Tornado warnings. 

PLEASE NOTE: When you hear sirens or local T.V. broadcasting interruptions other than Mondays at 12:30 noon you are directed to monitor your local Sarnia-Lambton radio stations for emergency instructions and for the most current information available. Stay tuned to these radio stations:

CHOK 1070 AM or THE FOX 99.9 FM or K106 106.3 FM
