Behind the scenes

 * Doctor Who was filmed in Vancouver, B.C. from 15 January to 21 February 1996, the first time a Doctor Who production had been mounted in North America. Canada remains the only North American country to host a complete production (other on-location episodes such as The Angels Take Manhattan and The Impossible Astronaut were still partially filmed in the UK).
 * Canada was the first country in North America (and one of the first outside the UK) to see broadcasts of Doctor Who when the Canadian Broadcasting Corporation debuted the first season in 1964 (it was cancelled 20 weeks later, however, following the conclusion of Marco Polo). Viewers in Edmonton, Alberta were also the first to see the 1996 TV movie, which aired there a few days before it was shown in the US. In 2005, Canada repeated history by once again becoming the first North American country (and one of if not the first non-UK countries) to see the revived series, again on the CBC, initially only two weeks after the UK broadcast.
 * The origins of Doctor Who also owe a debt to Canada, as Sydney Newman, considered one of the creators of Doctor Who, was a Canadian working for the BBC. He began his TV career as a producer for the CBC.
 * According to The Brilliant Book 2011, a reference book this wiki's policies do not consider to be a valid source, when solar flares threatened life on Earth, the nations of the world constructed starships, such as Starship UK, to house their populations. Starship Canada was among them.
