What Is Amateur Radio Service - LICENSED SERVICE
Industry Canada licenses the  Amateur Radio Service also referred to as Ham Radio, as a radiocommunication service in which radio apparatus is used for the purpose of self-training, intercommunication or technical investigation by individuals who are interested in radio technique solely with a personal aim and without pecuniary interest.

Ham Radio uses two-way radio as a means of communicating both locally and around the world.  Ham radio has even been used from space!  It's beginnings began with Morse Code,  progressed to Single Side Band, FM, TV, and now modern communications include computer technology such as Packet Radio and the APRS -Amateur Position Reporting System. 

Radio's used include HF short-wave for long range communication,  VHF/UHF/SHF for local and space communications. Hams have been involved with emergency communications such as major disasters/earthquakes.  We are ready to assist the public in these times of need.  

The Amateur fraternity includes meeting people from around the world with various interests from electronics or just a wish to communicate with others.  Some build their own radio's or antennas .. others contribute to advances in today's technology.. while even others talk to astronauts orbiting the earth. The International Space Station is currently active on the Amateur Radio bands.   Moonbounce or bouncing radio signals off the Lunar surface and communicating over long distances has also been done by hams using VHF/UHF/SHF frequencies. 

We have mountain top repeaters allowing region-wide communications over a large area. There are ham satellites orbiting the earth ready to relay earth-bound signals to all parts of the globe. You can even link Ham Radio over the internet using Voice-over-IP Software.  Amateur radio allows the experimentation of different methods of communications.

What Is Family Radio Service - UNLICENSED SERVICE
Industry Canada has introduced the Family Radio Service, referred to as FRS for short. FRS is a radio frequency assignment, that does not require a license, making it a popular solution for families. There are many makes and models of radios available from single channel to 14 channel.  For more information about the Family Radio Service, check out the following
Industry Canada Publication on FRS. 

Why Is FRS Important To Emergency Communications
Family Radio Service is important for emergency communications for two reasons; 1) To provide communications for emergency response and 2) To provide communications with people affected by the emergency.

FRS does provide some possibilities for short range emergency communications. This may be to communicate between rooms in an EOC, track people at an emergency site, etc., without tying up other more powerful communications bands and frequencies.

If you are providing emergency communications, you should be prepared to talk anyone who might have a radio. Common radios owned by the general public, are CB, Marine and now Family Radio Service.  If people own FRS radios, they will turn to these radios for communications in an emergency. It is important to know the frequencies, so you can monitor activity on the FRS frequencies.

While there are restrictions on transmission of signals on FRS, there is nothing to stop you from listening with any radio capable of receiving the assigned frequencies. This also allows the use of high gain external antennas, allowing greater possibility of hearing someone if they call.

For transmission, you will need a radio designed for FRS use. Not everyone will need an FRS radio, but it is a good idea to have a few available if required. One problem, is the the lack of knowledge that the general public will have about the radios. In an emergency, you can listen without any CTCSS, so you can hear everyone, however the person in trouble may have CTCSS enabled, so they will only hear you if you have the matching tone. 

Group A represents base station, mobile relay, fixed station, repeater outputs, or mobile station. Users can transmit up to 50 watts PEP.

Group B represents mobile stations, control stations, repeater inputs, or fixed stations operating in duplex mode. Users can transmit up to 50 watts PEP.

Group C represents those frequencies that are shared with the Family Radio Service [FRS]. Users can transmit up to 5 watts PEP.

Note that the 462.675 / 467.675 pair has been unofficially designated for use in emergency situations.

What Is General Radio Service - UNLICENSED SERVICE
The General Radio Service (GRS), popularly known as "CB", is a public communications, low-cost, short-range two-way radiocommunication service. The range varies, but is typically about 5 to 15 km, for car-to-car use; 12 to 25 km, for car-to-home conversations and 20 to 40 km between base stations.
