CHEK was the only local television station that operated on Vancouver Island for many years, until CHUM Limited signed on CIVI-TV (channel 53) in October 2001.

Only CBC owned-and-operated station CBUT-DT (channel 2) in Vancouver has been on the air longer, having signed on in December 1953.

Beginning around the 1978–79 television season, CHEK gradually added more CTV programs during the prime time hours (which were timeshifted from their airings on CHAN).

WIC bought the remaining 41% interest from Selkirk Communications in 1989, when that company sold most of its broadcasting assets.

In 1984, CHEK moved its operations from its original studios in Saanich to its present location at 780 Kings Road; the studio facility had originally been built to house a planned CBC Television station for Victoria, but budget cuts caused the plans to be shelved and then canceled.

CHAN and CHEK's affiliation agreements with CTV were originally due to end in 2000; they were extended to expire on September 1, 2001, in view of the uncertainty surrounding the local media landscape.

On February 5, 2009, Canwest announced it would explore "strategic options", including a possible sale of the stations, for CHEK and its other E!

owned-and-operated stations, on the basis that "a second conventional TV network [was] no longer key to the long-term success" of the company.

[3] On July 22, 2009, after failing to find a buyer, Canwest announced it would be shutting down CHEK on August 31, 2009, issuing layoff notices to the station's staff.

(which shut down a few days prior), and adopted a new schedule that included a mix of movies and older programming (both Canadian and American in origin), syndicated programming and a greater emphasis on local newscasts (including a new 10 p.m. newscast that debuted on September 1), and reverted to branding itself as simply "CHEK".

[21] Long time reporter Stacy Ross was named anchor of CHEK News at 5:00 and 6:30, after the resignation of Jim Beatty.

[22] In his first year, Fee oversaw the design and installation of a new upgraded set, new cameras, and made some fresh personnel changes.

[23] In 2021, CHEK carved out a new role by bringing in Rob Shaw, a longtime Vancouver Sun legislative columnist and reporter, as the station's first political correspondent.

[24] The same year, CHEK launched its foray into community podcasts, producing MicCHEK, Political Capital, Our Native Land and Chamber Chats.

[25] It also launched a popular newscast segment featuring positive news called "The Upside" hosted by Jeff King and Ed Bain.

Perkins' first move was recruiting Global BC morning show host Paul Haysom to take over as the 6 p.m. news anchor.

Perkins also promoted CHEK reporter April Lawrence to executive producer and hired long-time CTV Vancouver Island anchor/reporter Jordan Cunningham, as well as Our Native Land's Tchadas Leo as a multimedia journalist.

CHEK-TV was not the last analogue transmitter to shut down as part of Canada's August 31, 2011, digital conversion deadline in mandatory markets.
