Note: Due to the way this system works, not all transmissions are simulcast in all parts of the city, sometimes the Events channels 1-9 will not be heard on this stream, depending where in the city the emergency takes place. This feed is located in Scarborough picking up signal from the Birchmount tower.

Also, the TETRA system digital decoding can be glitchy at times, as well as broken up transmissions do come from the transmitting units themselves due to bad radio conditions in certain areas of the city or underground, as well as weather conditions such as rain or snow.
