CKLW hung on later than WABC and many other top 40s, going Music of Your Life in 1984 or 85 and Canadian News-Talk in 1991 or so. A couple of Big 8 revivals happened on the FM. What finished CKLW off was the refusal of the CRTC to allow the top 40 format to migrate to FM. Pat Holiday had painstakingly designed a format that met all the requirements (Cancon, hit/non-hit, etc) called 94 Fox FM. Jingles cut, billboards commissioned, staff practicing the format and then at the 11th hour the CRTC only allowed the format 4 hours a day with the rest of the day remaining Big Band, it.....and the whole operation....failed with a massive layoff.
