As part of CBIT's licence, it was not allowed to show local advertising, leaving CJCB with a monopoly in local advertising. CJCB's monopoly was reaffirmed in a CRTC decision in 1985 that denied a CBIT request to enter that part of the market. CHUM continued to own CJCB-TV until February 26, 1997 (with CRTC approval given on August 28, 1997), when it swapped the entire ATV group to Baton Broadcasting in a deal that saw Baton become majority owner of CTV.
