is a Canadian
radio network, which broadcasts weather
information. Owned and operated by Environment Canada
's Meteorological Service of Canada
division, the network transmits from 180 sites across Canada. In most locations, the service broadcasts on a special VHF
frequency audible only on special Weatheradio receivers, although in some locations — primarily national
and provincial parks
and remote communities — a transmitter operated by the Canadian Broadcasting Corporation
transmits the service on a conventional AM
frequency. As of August 2007, most of these transmitters are unlicensed by the CRTC
under a special license exemption granted to low-power non-commercial broadcasters.
The frequencies used for Weatheradio are the same frequencies used for its American counterpart, NOAA Weather Radio All Hazards, and weather radios designed for use in one country are compatible for use in the other.
Weatheradio has indicated that in the future, it also plans to add other emergency information, such as natural disasters, technological accidents, AMBER alerts and terrorist attacks, to its broadcasts.
