740 AM CFZM Toronto Ontario

CFZM (740 kHz) is a commercial Canadian AM radio station in Toronto, Ontario. It is owned by ZoomerMedia, headed by Canadian broadcaster Moses Znaimer. It airs an adult standards and oldies format, branded as Zoomer Radio, with the slogan "The Original Greatest Hits". The studios and offices are on Jefferson Avenue in the Liberty Village neighbourhood.

CFZM is a Class A, clear channel station. It transmits with a power of 50,000 watts, the maximum for Canadian AM stations. It uses a non-directional antenna, with its transmitter on Auburn Road in Milton, near Highway 401.Programming is also heard on a low power FM repeater in downtown Toronto on 96.7 MHz.

Due to its transmitter power and southern Ontario's flat land, CFZM has an unusually large daytime coverage area, equivalent to that of a full-power FM station. Its city-grade signal covers all of Southern Ontario, much of upstate New York (including Buffalo, Rochester and Watertown), northwestern Pennsylvania (including Erie), and slivers of Michigan and Ohio. Its grade B signal reaches as far east as Utica, New York, as far south as Pittsburgh and as far west as Lansing, Michigan. At night, with a good radio, it can be heard around most of the eastern half of North America, including three-fourths of Canada.
