CITY-DT
Canadian television station
CITY-DT (channel 57, cable channel 7), branded Citytv Toronto or simply Citytv, is a television station in Toronto, Ontario, Canada, serving as the flagship station of the Citytv network, a division of Rogers Sports & Media. It is sister to Omni Television outlets CFMT-DT (channel 47) and CJMT-DT (channel 40). The three stations share studios at the Rogers Building in downtown Toronto; CITY-DT's transmitter is located atop the CN Tower.
The station went on the air on September 28, 1972, by a consortium led by Phyllis Switzer, Moses Znaimer, Jerry Grafstein and Edgar Cowan, as CITY-TV, branded "Citytv" on Queen Street. In 1981, the station was sold to CHUM Limited, who retained Znaimer as an executive and moved to its 299 Queen Street West studios in 1987. For the majority of its early life, CITY-TV operated as an independent station, best known for its unconventional approaches to news and other locally produced programming. Under Znaimer's leadership, Citytv revolutionized Canadian local television by adopting a street-level, informal broadcasting style and creating interactive formats such as Speaker's Corner, which anticipated user-generated content platforms decades before the internet age. After having used syndication to bring its original programming to other Canadian markets, CHUM later used CITY-TV as the basis and flagship station of a television system, acquiring and establishing new stations under the Citytv name.
In 2006, CTVglobemedia announced its intent to acquire CHUM Limited, but was required to divest stations due to conflicts with CTV stations it already owned in Citytv's markets. CTV chose to keep the stations of CHUM's secondary A-Channel system, as well as CITY-TV's sister news channel CP24 and its other cable channels MuchMusic, but divested CITY-TV and its sister stations to Rogers Media.
This brief starts where responsible research should: with the source description of “CITY-DT” as canadian television station. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the places & architecture register because the source frames it as canadian television station. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Maps, plans, fabric surveys and administrative records can establish how the site’s name, extent and function changed over time. The source revision retrieved here is dated Sep 21, 2026. The linked authority identifier is Q2931559. None of the 2 selected statements returned an explicit reference. The first chronological checks are 1972, 1981, 1987 and 2006.
A single description cannot reconcile every naming convention, rebuilding phase or administrative transfer associated with a place. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
