The Marilyn Denis Show is a Canadian daytime television talk show which debuted on January 10, 2011 on CTV and CTV 2. Hosted by Marilyn Denis, the show airs weekdays at 10 a.m. on CTV and 11 a.m. ET on CTV 2. The show has a lifestyle-oriented format similar to Denis's previous Citytv talk show CityLine, but also regularly features celebrity entertainment guests, which are not commonplace on the Citytv program. Denis had left CityLine in 2008 following the split of the assets of CHUM Limited. The current program is produced in the same Toronto building in which CityLine was based during Denis's tenure, in the same studio as CityLine which was renovated specifically for the show. On November 17, 2015, the show celebrated its 1000th episode.
