CHNS-FM (89.9 MHz) is a commercial FM radio station, in Halifax, Nova Scotia, Canada.
It was the host of Canadian National Railway radio "phantom station" CNRH until that network was disbanded.
From the 1940s to the 1980s, CHNS employed personalities who would go on to become some of Canada's top broadcasters, including Knowlton Nash, Mike Duffy, Stan Carew and Ian Hanomansing.
Sister stations CKPE-FM in Sydney, CFQM-FM in Moncton and CJYC-FM in Saint John also do this.
The station was listened to around the world when it carried live coverage of the Moose River mine disaster in 1936.
Five-minute long hourly updates by CHNS reporter J. Frank Willis were relayed over CHNX for five days and were listened to worldwide and simulcast over 650 radio stations in North America.
It went off the air permanently in 2001 as station owner Maritime Broadcasting was unwilling to invest in a new transmitter.
