  • What is the Alert London Notification System?

    The Alert London Notification System allows you to opt-in to receive important public safety messages in the event of a community-wide emergency.

    The system is able to deliver notifications to residents and businesses via telephone, cell phone, text message, and/or email.

  • In the event of a city-wide emergency, how does the Alert London Notification System work?

    In the event of a large-scale emergency, the City of London will initiate geo-mapping technology to identify the location of the incident and then initiate the Alert London Notification System.

    The notification will be issued to residents and businesses living by or in close proximity of the emergency situation.

    Residents who have registered will receive the public safety information through the voice or text communication methods that they have selected.

    The Alert London Notification System will send the public safety message to the resident’s first choice point of contact (e.g. text, email address, cell phone).  Upon receipt of the notification, residents may be requested to confirm that they have received the public safety message.  If no confirmation is received, the emergency notification system may continue to attempt to reach residents through the other registered methods of notification until confirmation of receipt.

    The City of London encourages residents to register everyone in their family for this important service.  Of course, residents will always have the option to remove their contact information, in the event that they no longer wish to receive notifications.

  • The City's database and how it may be utilised during an emergency

    In the event of an emergency or significant event, the City of London will access a database for city of London listed residential and commercial phone numbers in order to initiate an emergency notification.

    However, the database excludes e-mail addresses, text, cell phone and some Voice Over Internet Protocol (VOIP) phone numbers.

    In order to ensure that you will receive emergency notification through your preferred method of contact, we recommend that you register your voice, text, and e-mail contact information.

  • Why should I register?

    We all have a role to play in ensuring that the city of London is prepared for an emergency and can respond effectively.

    The City of London, through the Emergency Management Program, works in collaboration with first responders and key stakeholders to ensure the safety of residents.

    Please consider registering family members to ensure that they also receive Alert London notification messages.  You can select their preferred method of contact.  For example, you can choose that your children receive Alert London notifications via text messages, and your parents via home phone number.

  • How do I register for the System?

    Visit to create your personal profile.  You can also sign-up family members and indicate their preferred method of receiving Alert London notifications.

  • What contact information can I register in the Alert London Notification System?

    You can opt to receive Alert London notifications by any of the following methods:

    • Home phone number
    • Personal cell phones
    • Personal e-mail address
    • Text
    • Work phone number
    • Work cell phone
    • Work e-mail address

    Please ensure that you update your contact information whenever it is changed.  It is important that the registered contact information is up-to-date.

    Please note that text messaging charges may apply, and the City of London is not responsible for any costs and expenses incurred by subscribers receiving alerts.

  • When will the Alert London Notification System be used?

    This system will be used to notify residents about community-wide threats to health and safety. The City will send notifications during emergency situations and disasters.  Notifications could also be requests to shelter-in-place or evacuate.

    The system may also be utilised to warn residents of developing community-wide threats to health and safety, such as a large-scale flooding event.

    Some emergency situations can evolve very rapidly, and there may not be enough time to provide emergency notification.  For example, in the event of a spontaneous event such as a tornado, it may not be possible to issue an emergency notification prior to the incident.  An emergency notification message may be provided after the event in order to relay public safety messages.

    The safety messages will outline steps to ensure personal safety and potentially protect or minimize damage to your property.

  • Will I still get emergency notifications if I do not sign up?

    Phone numbers listed in the database of land line service providers will receive a notification without having to sign up.

    You will not receive a notification by cell phone, text message, or e-mail address unless you register online


  • What if my phone number or e-mail address changes?

    The Alert London Notification System is only as good as the information you provide. If your contact information changes, you can always visit your profile and update your contact information.

  • What is the difference between Alert Ready and Alert London?

    Alert Ready is a system that allows the Federal, Provincial, or Municipal governments to send out notifications to the public over the television and/or radio.

    Alert London only provides emergency and public safety messages to the residents and businesses in the City of London.  Emergency notifications are sent to residents and businesses using the database and contact information registered on the Alert London public portal.

  • What are some examples of emergency situations that would trigger the Alert London Notification System?

    Examples of emergency situations that may trigger the Alert London Notification Systems include community wide events such as:

    • Power outage
    • Ice storm
    • Aftermath of a tornado
    • Boil water advisory

    Other situations that may trigger an Alert include:

    • Community evacuations
    • Hazardous material spills
    • Shelter-in-place
  • How can I register if I do not have access to the Internet?
