CFEQ

CFEQ began in 1999 as a low-power Christian station broadcasting in Winnipeg, Manitoba at 98.5 FM.  A short time later they moved to 107.1 FM and became "Freq 107".  CFEQ eventually dropped the religious music in favor of secular Alternative Rock.  Interestingly, their Wikipedia page says that the station "maintained that it fulfilled its conditions of license for religious music by finding spiritual meaning in each mainstream song that it played."  A name change to "Ignite 107" and a return to Christian Rock took place around 2008. 
107.1 FM is currently CKCL and airs a Classical music format.
