The multimedia giant said Wednesday that the affected positions represent a cross-section of its areas of business: including local radio and TV; sales, research and revenue management; marketing and communications; network operations; and news.
Jacqueline Milczarek, who has worked as an anchor on CTV News Channel since 2007, is among the public faces hit by the cuts.
Other on-air talent who were laid off include CHUM-FM host Amanda Logan and BNN anchor and correspondent Chitra Nawbatt.
"The difficult decision was made as the result of continued financial pressure in relation to the industry-wide challenging advertising market for radio and TV," said Bell Media vice-president of communications Scott Henderson in an email.
In June, Bell Media announced it would cut 120 positions across its television operations due to the tough advertising market as well as falling subscription revenues.
Henderson said the 80 jobs chopped on Wednesday were "new and additional," not a part of any previously announced cuts.
Last week, "etalk" host Tanya Kim and The Movie Network personality Teri Hart were laid off as part of the first round of job losses.
