Welcome to the Region of Waterloo Police live scanner feed. The audio player to your right may start automatically depending on browser used. Volume is adjustable by moving the white volume knob with your mouse (lower right on the audio player).

Listening to a police scanner can be a little confusing at first. The Police use a variety of codes for identification and to relay information. This eliminates the need for an 'on air explanation' between the officer and the Police dispatcher.  Two commonly used sets of codes are the "10 codes" and "900 codes". For example, 10-4 means "Message Understood", and if police are told to respond to a 935, they are responding to a possible "Intoxicated Person". Scroll down this page for the complete list of codes as you hear them used, and you will quickly understand what is happening.

Below are the "10 codes". You will hear a minor variation in the use of the words 10-4. 10-4 means "message understood", however, it is also used to confirm that an officer is alright, and the situation is stable.

You will hear a dispatcher say, "is everything 10-4 there?", or "are you 10-4?" The dispatcher is not interested in whether the message was understood, but wants to know if the officer is safe, and has everything under control.

10-1 Receiving poorly 10-5 Relay message 10-9 Repeat message 10-21 Call by telephone 10-61 Has record - not wanted 10-65 Assist with 10-64
10-2 Receiving well 10-6 Busy - stand by 10-10 Switch common channel 10-33 Emergency 10-62 Subject possibly wanted 10-66 Observation category
10-3 Stop transmitting 10-7 Out of service 10-19 Return to station 10-36 Correct time 10-63 Subject wanted 10-67 Parolee category
10-4 Message understood 10-8 In service 10-20 What is your location? 10-60 Subject negative 10-64 Proceed with caution 10-68 Charged category

You will often hear a police dispatcher refer to a C-N-I (Criminal Name Index). A "positive C-N-I" means the person in question has been listed in the CNI police computer system with certain "Flags" (see below). Other information from a C-N-I is usually clearly explained by a dispatcher.
Flag A Believed Armed Flag C Believed Contagious Flag E Escape Risk Flag F Family Violence
Flag M Believed to be Mentally Ill Flag R Unknown Flag S Believed Suicidal Flag V Believed Violent

The Region of  Waterloo Police units communicate using individual designations. All known designations are listed below. The first letter, number or word lets you know their association within the police department.

For example, if the dispatcher makes a call to unit "South 11C", you know they are contacting a unit from the Cambridge Division. All unit designations starting with the word "South" are being handled by the Cambridge Division. See the entire list below.

Some of these designation may be combined together. A call sign starting with the letter "S" indicates a Sergeant. However, when combined with "Central" (example  "Central S23") , you know the dispatcher is contacting a Sergeant  from the Kitchener (Central) Division.

Scanned Police Frequencies

The Region of  Waterloo employs an EDACS trunked radio system for their Police, Fire, Transportation and other city services.

What is EDACS? EDACS is a radio communications system that provides high-speed wireless analog voice, digital voice, and data communications.

This EDACS system allows groups of users to communicate with each other as if they were standing in the same room. The system is comprised of  primary control channels and alternate control channels. At any given time, each site (Police, Fire, City Services etc.) has one control channel. The remaining channels are used as working channels, and functions such as call queuing, emergency calls, and call prioritization are always available.

Within this EDACS system are literally hundreds of individual 'talkgroups'. A talkgroup can be thought of as an individual party line. Everyone listening on a specific talkgroup will hear everything said on that particular talkgroup. For example, all the police on talkgroup 00-021 (Central (Kitchener) Division 1) will hear everything said on that particular talkgroup only.  They will not hear anything from the South (Cambridge) Division 2, because they are on a different talkgroup ( talkgroup 00-022).

Different Police Divisions, Detectives, Emergency Response Units, Fire trucks etc. will all have their radios tuned to different talkgroups depending on their individual specialties.

The Police scanner is programmed to receive certain talkgroups from within the Waterloo Region EDACS system, and are listed below. Primary control frequencies ( also listed below) are in red.

Not all possible talkgroups are scanned and broadcast. It is felt to be inappropriate to publically re-broadcast certain tactical and sensitive talkgroups.
