Polka Dot Door is a Canadian children's television series which was produced by the Ontario Education Communications Authority (later known as TVOntario) from 1971–1993. The series features two hosts who acknowledged and presented directly to the home viewing audience. The content of the shows was generally geared towards education and creativity. Each week of episodes focused on a single theme with each weekday assigned a different "motif" in which the theme was explored in different ways (For example, Tuesdays were "Dress-Up Day" in which the hosts would use costumes to explore the theme).
