Annual Test of Greater Sudbury Emergency Notification System

Apr 17, 2019

To kickoff Emergency Preparedness Week from May 5 to 11, 2019, the City of Greater Sudbury will test its Sudbury Alerts emergency notification system. The test will take place at 10 a.m. on Wednesday, May 1, 2019.

There are several reasons why you may receive a test notification on May 1.

The City has over 69,000 public home and business phone numbers. If your home or business is one of them, you will receive a test notification on your home or business phone. If you have signed up to receive emergency notifications via text, email, TTY or mobile number via the City’s website, you will also receive a test notification.

The incoming Sudbury Alerts call will appear on your phone as 705-805-9360.  It’s a good idea to include the number in your phone’s contacts and name it Sudbury Alerts so you always know when an emergency alert call is coming in.

When you receive your test notification, please follow the instructions carefully so we can ensure the system is working properly. Please do not call 311 or 911 when you receive your test notification.

To sign up for Sudbury Alerts, visit If you have already signed up, you can log back in to ensure your information is up to date, or change your language preference.

In the event that an actual emergency occurs on May 1, the word TEST will not be part of the messaging. Instead, the message will give specific details of an emergency and how you should proceed.  The test message will be clearly marked with the word TEST in written form and emphasized in voice recordings.

Sudbury Alerts provides emergency information specific to residents of Greater Sudbury. This is a separate system from Alert Ready, the national system, which allows government officials at the federal, provincial and municipal levels to issue public safety messages via channels such as television, radio and wireless devices based on one’s geographic location. There is no sign-up or opt-in required for the national Alert Ready system.

Sudbury Alerts, however, focuses on local emergencies, including train derailments, dangerous weather, potential air quality issues and other. It can also deliver important messages about when to shelter in place and where to go for detailed information during a local emergency.

Sudbury Alerts messages are available in English or French upon sign up. If you do not choose your language preference, the notifications will default to English. If you’d like to change your default settings, please sign it at
