It aired live at 4PM weekdays and was initially hosted by John Majhor.
Majhor was a longtime DJ at 1050 CHUM AM in Toronto and eventually became one of Canada's first "VJs" with the development of music videos.
Toronto Rocks was a local contemporary to MuchMusic and MTV (CITY-TV and MuchMusic were both owned by CHUM Ltd.), and had kids rushing home from school every day to catch their favourite videos of the early-to-mid '80's.
During the show, Majhor played videos by a wide variety of the big-name artists of the day, all the way from Michael Jackson's "Beat It", Van Halen's "Jump", Yes' "Owner of a Lonely Heart", to the Eurythmics' "Sweet Dreams (Are Made of This)" and other songs released in the 1980s by artists who became commercially popular during the decade.
