[1] On November 24, 2000, through a joint venture, Rogers Media (33.34%), Shaw Communications (33.33%) and TechTV US (33.33%) were granted approval by the Canadian Radio-television and Telecommunications Commission (CRTC) to launch a Canadian version of the U.S. television channel TechTV, described by its nature of service as "providing programming about computing, technology and the Internet.

[3] As part of the purchase, Comcast acquired TechTV's 33.33% interest in the Canadian version, spinning it off into its subsidiary, G4 Media.

G4 Canada's social media channels went dormant but still active after that point, with its website remaining in the same design since the early 2010s (though new content continued to be cycled in).

The representative cited "the current competitive television landscape" and a desire to focus on Rogers' "core specialty portfolio"; some of its programming were moved to Citytv.

Canada never received the limited relaunch of G4 from the United States in the fall of 2021 before its shutdown nearly a year later, though some of its content was available region-free via YouTube and Twitch.

The government-owned Caribbean Broadcasting Corporation in Barbados switched from providing the American-based feed, in favour of the Canadian channel for its cable television network known as Multi-Choice TV.
