 However, CHEX-TV-2 provided exclusive terrestrial coverage of CTV programming in most of the Durham Region and Toronto's east side, as CFTO's digital signal on VHF channel 9 is nulled to the east.The switch was approved by the CRTC on August 27, 2015, when it dismissed objections by Rogers Media and by a resident who complained that as he only received television over the air, he would lose his ability to receive CBC Television as a result of the disaffiliation.Legally, CHEX-TV-2's affiliation with CTV was described as a "program supply agreement," and not as an "affiliation" (a term with specific legal implications under CRTC rules), as Corus maintained editorial control over the stations' programming and the ability to sell local advertising, and did not delegate responsibility for CTV programs aired by the station to Bell Media.
