package, which is in a blue and white color scheme, a revised logo (similar to those already used on CTV News Channel and CTV National News), and new theme music. Starting in 2019, a red color scheme was added to the graphics package. National aggregate ratings published by BBM Canada refer to the local broadcasts collectively as CTV Evening News, CTV Late News, CTV Noon News, etc., although these titles are not used on-air. Since most CTV affiliates are owned by the network, CTV offers the opportunity to buy national ads on local programming across its O&Os, making these aggregate ratings useful for advertisers. Local CTV News programs are produced in the following markets: Barrie (CKVR) (in HD) Calgary (CFCN) (in HD) Edmonton (CFRN) (in HD) Greater Sudbury (CICI) Halifax (CJCH / CTV 2 Atlantic) (in HD) Kitchener (CKCO) (in HD) London (CFPL) (in HD) Montreal (CFCF) (in HD) Ottawa (CJOH / CHRO) (in HD) Regina (CKCK) (in HD) Saskatoon (CFQC) (in HD) Toronto (CFTO) (in HD) Vancouver (CIVT) (in HD) Victoria (CIVI) (in HD) Winnipeg (CKY) (in HD) Windsor (CHWI) (in HD) CTV O&Os in smaller markets air a newscast produced in one of the larger markets noted above, although some may also produce a shorter local news insert aired during a break in the main market's program, and some of these smaller stations produce their own noon newscasts. Through the purchase of CHUM Limited, Bell Media acquired A News which produced local newscasts mainly in smaller markets or alternate areas of larger markets. When the A system was rebranded as "CTV Two" on August 29, 2011 (and later CTV 2), its newscasts switched to the CTV News branding, likely because "CTV Two News" might be seen as connoting a second-class newscast. The CTV News broadcasts on the CTV 2 stations previously used the main CTV logo as their logo bug during these newscasts as did the main CTV network, but they currently use the regionally branded titles such as CTV News Barrie as is now the case for the CTV O&Os. Most of these stations are nevertheless required to separate their news operations from CTV stations in local and adjacent markets. This restriction does not apply to the cable-only channels CTV Two Atlantic, which has been co-owned with the local CTV stations since its launch (their news operations have been fully integrated since 1998), and CTV Two Alberta,
