CIWW (1310 AM) was a radio station in Ottawa, Ontario owned by Rogers Radio. The station was the oldest radio station in Ottawa, first signing on in 1922. The station broadcast at 50,000 watts, the maximum for Canadian AM stations. The transmitter site was on McKenna Casey Drive, near Strandherd Drive and Ontario Highway 416 in Nepean.[2] To protect other stations on 1310 AM, it used a directional antenna. By day it employed a two-tower array and at night a five-tower array. The nighttime signal was beamed mainly into Canada. The towers were removed sometime in late 2023.[3]
In 2020, the station added an FM simulcast on CJET-FM. On October 26, 2023, the station was closed by Rogers after just over 100 years of operation.
