Sudbury Alerts

The City of Greater Sudbury has launched a mass notification service that allows us to notify residents of any imminent threat to public safety. Sign up to receive these notifications by using this voluntary portal and opt-in with your contact information. 

The information you provide is protected and will not be used for any other purpose.

How does it work?

When a notification is issued about a potential safety hazard or concern that is considered an imminent threat to public safety, you will receive a message via voice or text depending on how you requested to receive messaging. If requested within the notification, you can confirm that you have received the message and you will not be contacted by any subsequent methods regarding that particular notification. If you do not confirm, the system will continue to attempt to reach you at all of the contact systems that you have registered.

Sign Up For Notifications

Create an account and add your contact and location information to your profile. The system will accept land line numbers, cell phone numbers, email addresses, TTY services, and fax numbers. All information you provide will be kept confidential.

Stop Receiving Notifications

Should you wish to delete your profile, you may still receive emergency notifications if you have a publicly-available phone number.  

To delete your profile, please email

What is Sudbury Alerts?

Sudbury Alerts is a mass notification system used by the City of Greater Sudbury to issue emergency notification to the public of community-wide and localized emergencies, as well as other significant situations that may affect public safety. The system delivers notification to residents and businesses via telephone, cell phone, text message, fax or email.

What is the difference between Alert Ready and Sudbury Alerts notifications systems?

Alert Ready is a system that allows Canadian government officials at the federal, provincial and municipal level to issue all types of public safety messages. It is designed to send notifications to the public over radio and television. Sudbury Alerts only provides emergency information specific to residents of Greater Sudbury. Emergency notifications are sent to residents via contact information listed in the White or Yellow Pages as well as contact information registered on the member portal.

In the event of a city-wide or area specific emergency here in Greater Sudbury, how does the Sudbury Alerts system work?

Timely, trusted and targeted emergency notification messages will be sent to you via text to a cell phone, voice mail recording to your home or work phone, and/or an email message depending on your individual preference. The Sudbury Alerts system has a high priority calling status and capacity to reach tens of thousands of residents within seconds. Sudbury
Alerts can also be targeted to only send messages to residents  in a certain area or neighbourhood.

What are some examples of emergency situations that would trigger the Sudbury Alerts system?

Examples of emergency situations that would trigger Sudbury Alerts notifications include extreme weather situations (i.e. tornadoes), hazardous material spills, wildfires or other situations that could create an imminent threat to public safety. In the case of a required evacuation, shelter-in-place or other emergency situation, Sudbury Alerts will be used to share emergency action messages so you can take steps to ensure your personal safety and potentially protect or minimize damage to your property.

Why should I subscribe to Sudbury Alerts?

We all have a role to play in ensuring our community is prepared for an emergency and can respond effectively to a disaster.  The City of Greater Sudbury, through the Emergency Management Office, works with trusted local agencies to ensure the safety of our residents. 

How do I sign up for the system?

Visit to create your personal profile. You may also sign-up family members and indicate their preferred method for receiving Sudbury Alerts emergency notifications. For example, you can choose that your children receive Sudbury Alerts notifications via text messages, while your preferred method to receive notifications is via email.

Will I still get emergency notifications if I don’t sign-up?

If you don’t sign up, you may still receive emergency notifications on your home phone if the number is publicly available through the White or Yellow Pages. However, it's always best to sign up to make sure we have your correct contact information and to allow you to customize the way you would prefer to be notified. 

Why can't I register as a family?

It is recommended you sign up for the alerts as an individual, rather than by family unit. This ensures the notification system reaches all parties through their own personal contact devices.

Should I call 911 when I get an emergency notification?

No. If you get an emergency notification regarding a situation in your area, the 911 systems are already aware of the situation and very busy. Instead, follow the notification instructions.

Should I wait for an emergency notification before I evacuate or shelter-in-place?

If you are aware of a situation occurring in your area, do not wait for a call if you do not feel safe. Take action as you see fit depending on the emergency.

Will my contact information be shared with others?

No. The information you provide will be used for emergency purposes only. We will not give or sell your information to any other vendor, service or organization. Personal information collected is pursuant to the Municipal Act, 2001 as amended and will be used for the administration of the municipality.

I use a TTY device – can I receive messages that way?

Yes, you may register two TTY contact numbers per household.

I don’t have access to the Internet. How can I subscribe to Sudbury Alerts?

There are places around Greater Sudbury with free internet services including Greater Sudbury Public Libraries. Greater Sudbury Emergency Services conducts ongoing education and outreach activities throughout the city to provide information about the Sudbury Alerts system, and can assist residents with their Sudbury Alerts sign up. 

What if my phone number or email address changes?

If your cell phone, work phone or email address changes, you are responsible for going to the website and updating your information. 

If a notification is sent out is it guaranteed I will receive it if I register?

When the emergency notification is activated, the system will make several attempts to reach the registered numbers. Due to the emergency, phone systems including land line and cell service may be inundated with calls and your provider may not be able to deliver the message. We do not assume legal responsibility for technical difficulties that may result in notification failures.

How often will Sudbury Alerts be tested?

Sudbury Alerts will be tested annually during Emergency Preparedness Week in May. Residents will be notified in advance so they have time to check their settings and make any necessary changes.

Who can I call if I have questions or troubles logging in or signing up?

If you have any questions regarding Sudbury Alerts, please contact 311 or email
