What is Alert Ready?
Alert Ready is designed to deliver critical and potentially life-saving alerts to Canadians through television and radio. The Alert Ready system is developed in partnership with federal, provincial and territorial emergency management officials, Environment and Climate Change Canada, The Weather Network and the broadcasting industry and wireless service providers, to ensure you receive alerts immediately and know when to take action to keep yourself and your family safe.
Who sends emergency alerts?
Federal, provincial, and territorial governments are responsible for issuing emergency alerts.
Federally, emergency alerts are issued most frequently by Environment and Climate Change Canada.
Each provincial or territorial government decides who will have the authority to issue alerts within their jurisdictions. For example, emergency alerts could be issued by provincial or territorial emergency management offices or in some cases by municipal emergency management offices or local police and fire departments.
Media companies, including television, radio stations, cable and satellite distributors, as well as websites receive these emergency alerts and relay them to their consumers.
Beginning April 6 2018, wireless service providers will be capable of distributing emergency alerts received from alerting authorities directly to their consumers’ compatible wireless devices connected to LTE networks using Cell Broadcast distribution.
What types of emergency alerts are issued via Alert Ready?
The Alert Ready system allows alerting authorities from federal, provincial and territorial governments to issue a wide range of public safety messages. However, broadcasters and wireless service providers are only required to distribute emergency alerts for situations that pose an immediate threat-to-life.
Government officials developed and agreed on a specific list of the types of alerts that are considered a threat-to-life and should be distributed immediately on television, radio and wireless devices. These “Broadcast Immediately” emergency alerts have the highest level of severity, urgency and certainty. For a full list, visit the Alert Types section of the website.
Issuing alerts outside of this list (for example heavy rainfall or blizzard warnings) is at the discretion of each of the broadcasters. Wireless service providers will only receive and relay messages that are issued for threat-to-life situations.
How do I know if the alerting authority in my area will issue emergency alerts?
Visit the Test Schedule and Alerting Info section of AlertReady.ca for information how emergency alerts are used in your province.
Federally, emergency alerts are issued most frequently by Environment and Climate Change Canada. It is important to note that the federally-issued emergency alerts can reach your compatible wireless device in any part of the country even if your province/territory is not using the Alert Ready system.
What are the different ways I will receive emergency alerts?
You can currently expect to receive emergency alerts via Canadian radio and TV, cable and satellite operators. As early as April 6 2018, emergency alerts will also be sent to compatible wireless devices connected to LTE networks.
Can I choose which way an emergency alert is sent to me?
No. Regulations require all commercial, campus, community and Indigenous radio and television broadcasters, cable, satellite and IPTV providers, as well as wireless service providers to distribute emergency alerts.
There is no sign-up or opt-in required. Emergency alerts will be automatically sent through these broadcast channels, and to your compatible wireless device.
You cannot opt out of receiving threat-to-life emergency alerts.
What do emergency alerts look and sound like?
Emergency alerts, on radio, television and compatible wireless devices, begin with a distinct sound, known as the Canadian Alert Attention Signal. Emergency alerts sent to WPA-compatible wireless devices will also cause the phone to vibrate. The sound and vibration conveys a sense of urgency and reinforces the alert message. For an example of the Alert Attention Signal, click here.
On television and radio, the emergency alert sound will be followed by an automated message with the emergency alert details. On television, the emergency alert details in text will be presented either as a full screen or a crawler section at the top or bottom of the screen.
On compatible wireless devices, the emergency alert will display an “EMERGENCY ALERT/ALERTE D’URGENCE” banner, followed by text that describes the situation and provides instructions on what actions to take and where to find more information. At the top of each emergency alert, the issuing government agency will be clearly indicated.

Will emergency alerts be sent out in different languages?
Alert Ready supports emergency alerts in both English and French. However, the language used for alerts is determined by each alerting authority. Generally, alerting authorities will issue emergency alerts based on the official language requirements of their organization or jurisdiction. Broadcasters and wireless service providers pass on emergency alert text exactly how it is received from the alerting authority.

Are emergency alerts available in alternate formats to accommodate the visually and hearing impaired?
Yes, alternate formats can be issued, but not every alerting authority or every device will have the capacity to produce alternate formats. For example, emergency alerts distributed via radio and TV broadcast can include an audio file version of the text portion of the emergency alert message if one is provided by alerting authorities. If audio files are not provided, broadcasters may use text-to-speech software to create an audio version of the message. For emergency alerts distributed via compatible wireless devices, emergency alerts may be read to the recipient if their device supports this accessibility feature. The vibration feature that accompanies emergency alerts sent to compatible wireless devices will help to make hearing impaired people aware of the alerts.
Will emergency alerts be for my specific area?
Yes. The alerting authority determines what areas are affected by an incident, weather or environmental situation, and uses a standard system that will typically correspond with municipal, regional or provincial boundaries. The standardized system will allow participating radio, television, cable and satellite companies to broadcast the emergency alerts that are most relevant to the communities they serve.
Emergency alerts intended for wireless devices are issued to a defined geographic area, which can be as small as a few city blocks, so that only people in the defined area receive the emergency alerts. Compatible wireless devices in the targeted area will receive the emergency alerts within seconds of being issued, provided the phones are powered on and connected to the LTE cellular network.
What should I do if I receive an emergency alert?
Upon receiving the emergency alert it is important to take action safely. Alerting authorities will include, within the emergency alert, the information you need for any action you need to take. This could include but is not limited to: limit unnecessary travel, evacuate the areas, shelter-in-place, etc.

How will I know when an emergency alert has ended?
Alerting authorities may choose to distribute an “all-clear” message at their discretion once the situation has been resolved. The all-clear message would be distributed via broadcast services at their discretion but will not be sent to wireless devices.
As part of an emergency alert message, alerting authorities must also set a time when they expect the alert to expire. The expiry time is different from the “all-clear” message, as it is set in advance and does not necessarily indicate when an emergency is over. Because each emergency alert issued requires that an expiry date and time be included, alerting authorities estimate when they think the alert will need to be updated or cancelled.
Are a lot of emergency alerts being issued?
The amount and type of emergency alerts vary by jurisdiction. Emergency alerts for threat-to-life situations are infrequent.

Will multiple emergency alerts be generated for the same event if sent by multiple alerting authorities?
This situation is very unlikely. Emergency management officials are experts in their fields and coordinate activities, including public alerting, very closely and will be monitoring emergency alerts issued by neighboring jurisdictions.
What type of security is in place so that I know the emergency alerts are being sent by an authorized agency?
The operator of the Alert Ready system and government officials at all levels take security very seriously.
In addition to the security measures that government agencies take every day to ensure access to their system is by authorized personnel only, additional passwords and user identification is needed for users of the Alert Ready system. Separately, Pelmorex Weather Networks (Television) Inc., the operator of the Alert Ready system, has additional measures in place to prevent unauthorized access.
I work with emergency management, the police or fire department, how can we access Alert Ready and distribute messages to our community?
Each province and territory has signed on to the Alert Ready program. Please contact your provincial or territorial Emergency Management Office for public alerting information specific to your region.
