In November 2012, the station started edging away from using the "Citytv" branding in its voiceovers, and began calling itself "City Television", although the "Citytv" branding was still heavily seen in promos and on bugs on the lower-right portion of the screen.
The channel used the same news wheel format as CFTR with traffic and weather reports at the top and bottom of every hour, sports news at 15 and 45 minutes past the hour and business news at 26 and 56 minutes past the hour.
In addition to rolling news programming, City News Channel aired simulcasts of Citytv Toronto's news programming, and an audio feed from CFTR during the overnight hours.
In July 2001, however, CHUM purchased CKVU-TV in Vancouver from Canwest Global Communications; CKVU changed its branding to "Citytv" in July 2002, making Citytv a two-station system.
In 2005, three more Citytv stations were added in Calgary (CKAL), Edmonton (CKEM) and Winnipeg (CHMI) after CHUM purchased the A-Channel television stations and other assets owned by Craig Media (the existing A-Channel brand was revamped and was transferred to CHUM's former New Net stations).
The four principal owners raised over $2 million to help start up the station, with Grafstein raising about 50% of the required funds, Znaimer raising around 25%, and the remainder being accrued by Switzer and Cowan.
The channel 79 licence was granted to the company on November 25, 1971.
The founding ownership group Channel Seventy-Nine Ltd.
consisted of – among others – Phyllis Switzer, Moses Znaimer, Jerry Grafstein and Edgar Cowan.
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.
The Citytv stations (including CITY) were subsequently sold to Rogers Communications: the sale was approved by the CRTC on September 28, 2007, and Rogers took ownership on October 31. As such, Rogers had to find a new home for CITY-TV's operations.
