Auxiliary Communications Service   (aka A.R.E.S.)

Field Services Organization




The Auxiliary Communications Service (A.C.S.) is a group of dedicated, Industry Canada licensed, radio operators who volunteer their services and equipment to provide auxiliary communications in times of need. Amateur Radio operators have been doing this since 1935. We are fortunate in this country to have one of the most reliable telephone systems in the world, but in an emergency it can become overloaded and unusable. During these critical times we sometimes have to communicate in a more timely fashion to prevent loss of life and property.


ACS can be called upon in these times of crisis to help provide critical communications, to supplement, not to replace, existing radio communications systems. This service is provided free of charge. The A.C.S.  Emergency Coordinator works with municipal and provincial officials and agencies, and others, in order to maintain communications during an emergency. ACS also works with another group of Amateur Radio operators who run the National Traffic System (NTS), to send messages locally, nationally and internationally.


The head of the local A.C.S. group is the Emergency Coordinator (EC). The EC is given the task of developing an Emergency Plan and training radio operators, to be ready in the event that normal communications are disrupted. The EC also works with ECs of neighboring counties, the District EC, and the Section EC (Ontario) during wide-spread disasters.


The A.C.S. holds drills on a regular basis, called SETS or Simulated Emergency Tests in November, as an exercise for local and national emergency radio networks, particularly using the NTS to transmit emergency radio traffic. A.C.S. encourages anyone interested to come out and see first-hand our communicators in action!


How can the A.C.S. help your organization? Discuss your needs with the A.C.S. Emergency Coordinator; we will try to accommodate your needs. We have a videotape showing how we operate during emergencies, and would be glad to arrange a viewing for your organization.


If you're a radio amateur, and you'd like to volunteer for the A.C.S., contact your local Emergency Co-ordinator.  There is no membership fee, and you need not belong to any other amateur organization. All you need is a willingness to help!


If your community or charitable event needs reliable radio communications for health and welfare, safety, security or logistics, please contact the A.C.S.

Simulated Emergency Test 2021: October 27 | October 30

The Simulated Emergency Test (SET) is a North America-wide exercise in emergency communications, which is administered by Radio Amateurs of Canada (RAC) and the American Radio Relay League (ARRL). In Canada, this is done by RAC's Emergency Coordinators (EC) and Net Managers (NM).

In Ontario the Simulated Emergency Test will be held on Saturday, October 30 from 9 am until 12 noon local time. At Emergency Operations Centres located in Municipal offices in which access is not available on the weekend, the SET may be held on Wednesday, October 27

Note: The date and time of the SET are contingent on the restrictions resulting from the global pandemic. All participants in the Simulated Emergency Test should follow the guidelines provided by the government and health officials in their respective areas.

A High Impact, Low Frequency Event

This year, we are once again implementing themes and scenarios which will be relevant at the local level and enable local ECs to focus on dedicated communications tasks that are commonly found in real-life events. A high impact, low frequency event (HILF) is the realization of a specific hazard that has the potential to produce a high impact on grid operability. Such high impact events are, by virtue of their rarity, considered low frequency.

Purpose of the Simulated Emergency Test

The RAC Simulated Emergency Test is an ideal opportunity to demonstrate the capabilities of Amateur Radio. Both the Auxiliary Communication Service (ACS) and the National Traffic System (NTS) are involved in the exercise.

The objectives of the SET are:

1) To find out the strengths and weaknesses of the ACS, NTS and other groups providing emergency communications.

2) To provide a public demonstration to served agencies - government officials, the Red Cross and other NGOs - of Emergency Preparedness and, through the news media, of the value to the public that Amateur Radio provides, particularly in time of need.

3) To help Radio Amateurs gain experience in communications using standard procedures and a variety of modes under simulated emergency conditions.

Through the SET, we aim to develop a strong relationship between the new Auxiliary Communications Service and the various government officials and relief agencies we serve. It is vitally important that this be done by the Emergency Communicators (ECs) at the local level. Should you require assistance in your region contact your Section Emergency Coordinator or Section Manager for advice.

The event provides an opportunity for Amateurs to focus on the emergency communications capability within your community, while interacting with NTS nets, Community watch programs and other agencies (if allowed).

SET Reporting Procedures

Once the SET has been completed, participating Emergency Coordinators, Net Managers or other representatives must complete the SET forms which are provided on the RAC website at: Please send a copy to your Section Manager (SM) and to your Section Emergency Coordinator (SEC) or Section Traffic Manager (STM) as applicable. The deadline for receipt of all reports is January 31, 2022.

To find out how you can step up and be a part of the local or Section-level activities, please contact your Section Manager ( For more information on the SET visit:
