The series also has a fan base in the United States, where it was shown in syndication from the 1970s to the 1990s, particularly on PBS stations.

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 introduced the episode and then, after the episode concluded, tried 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.

Series three began broadcasting on CBC on 18 June 2007 followed by the second Christmas special, " The Runaway Bride ", at midnight, and the Sci Fi Channel began on 6 July 2007, starting with the second Christmas special at 8:00 pm E/P followed by the first episode.

Series four aired in the United States on the Sci Fi Channel (now known as Syfy), beginning in April 2008. It aired on CBC beginning 19 September 2008, although the CBC did not air the "Voyage of the Damned" special. The Canadian cable network Space (now known as CTV Sci-Fi Channel) broadcast "The Next Doctor" (in March 2009) and all subsequent series and specials.

The series was aired in Brazil at the TV networks Syfy and, more frequently, at the public broadcaster TV Cultura. Expect international distribution rights holders, it had already been made available on local streaming platforms Looke and Globoplay. Starting from 2024, the previous 13 series will be available at the upcoming streaming service +SBT.
