context: TVOntario picked up the show in 1976 beginning with The Three Doctors and aired each series (several years late) through to series 24 in 1991. From 1979 to 1981, TVO airings were bookended by science-fiction writer Judith Merril who would introduce the episode and then, after the episode concluded, try to place it in an educational context in keeping with TVO's status as an educational channel. Its airing of The Talons of Weng-Chiang was cancelled as a result of accusations that the story was racist; the story was later broadcast in the 1990s on cable station YTV. CBC began showing the series again in 2005. The series moved to the Canadian cable channel Space in 2009.[citation needed]
