CKRZ-FM

[1] Its frequency is 100.3 FM and is available on Rogers cable, channel 951 in Brantford, Kitchener, Woodstock and London.

On January 29, 2009, the station announced that due to a rising debt load of more than $100,000 and reduced advertising revenue, it would leave the air on February 1, 2009.

Juchniewicz called Six Nations one of the nicest communities he had ever worked in, adding that "there are a lot of good people at that station and it's got a better chance of recovering than some of the bigger broadcasters that are in trouble now, too.

It was temporarily reduced to automated programming, with a single live personality to read news reports and community announcements, in order to give SONICS time to eliminate the station's accumulated debt.
