In-universe, the Doctor has visited numerous places on Earth, past, present, and future.
Doctor Who, the production, has on occasion shot on location outside of the U.K. From the original run, "City of Death" featured location scenes in Paris. In the new run, "The Angels Take Manhattan" featured location scenes in New York. Apparently, the 1995-96 movie was co-produced with Canadian involvement and shooting occurred in Vancouver, B.C..
Counting only stories which were shot and aired as part of the "official" show, have any stories ever been set in Canada, past, present, or future (even if locations elsewhere stood in)? Apparently, Canada comes up a certain amount, but have scenes played out ostensibly on Canadian soil (even if not actually shot there)?
