 The affiliation switch took effect on August 31, 2015.Due to the overlapping coverage discussed above, most TV service providers serving the region already carry CBLT, and any that do not will have to add a CBC affiliate such as CBLT to their basic services in order to comply with Canadian Radio-television and Telecommunications Commission (CRTC) regulations.CTV already served the CHEX-TV-2 viewing area through its Toronto O&O CFTO-DT; in consequence, the Toronto market was then served by two CTV outlets in most parts of the market (CFTO plus either CHEX-TV-2 or CKCO-DT in Kitchener).
