The Canwarn program is an organized severe weather spotting and reporting program organized and run by the Meteorological Services Division of Environment Canada. The program was established in 1987 after the Edmonton Tornado at the request of the Hage Report and put into full service the following year. Within a week after the Hage Report, over 120 amateur radio operators in the Windsor, Ontario area were trained and another 100 in Edmonton, Alberta. Organized storm spotting in Canada had existed prior but operated independently of Environment Canada and never fully achieved the success that the Canwarn program did. Initially, Canwarn was predominately based in southern Ontario and central Alberta but eventually grew to encompass the entire country by the early 1990's.
