CFZM is a Canadian Class A clear-channel radio station, licensed to Toronto, Ontario, which airs at 740 kHz on the AM radio dial and in downtown Toronto at 96.7FM. The station airs a pop standards format branded as Zoomer Radio, with the slogan "Timeless Hits". Its studios are located in the Liberty Village neighbourhood, while its transmitter is located in Hornby.
CFZM is perhaps the only remaining adult standards-formatted station in North America that broadcasts a 50,000-watt clear channel signal. The station's nighttime signal blankets most of the eastern half of North America—including three-fourths of Canada and just over half of the United States. It can reach as far west as Minneapolis and Winnipeg, and as far south as New Orleans.
CFZM's daytime signal can be heard as far north as Georgian Bay; as far south as Youngstown, Ohio; as far east as eastern Massachusetts and New Hampshire including Nashua, Lawrence and Portsmouth; and as far west as the Michigan Thumb. Such signal strength allows CFZM to often register significant Arbitron ratings in such markets as Buffalo, New York and Erie, Pennsylvania, cities where disenfranchised listeners of former adult standards station WRIE can easily pick up CFZM. Although WECK in Buffalo recently returned to an adult standards format; CFZM offers instrumentals (in the form of a Sunday evening 4-hour big band program) and many specialized music programming blocks. WECK offers very few instrumentals and the only specialized music block WECK has is a weekly 3-hour polka music show. CFZM offers online streaming of their audio through their website.
