Definitely Not the Tunnel of Love
But rather, this scene reminds me of those Bionic Woman episodes in the 1970s, especially the revolving tunnel episode involving the Sasquatch! This particular tunnel is much more important than that: it is actually the entrance to the Diefenbunker, a cold war museum and underground bunker located in Carp, Ontario 25 km west of Ottawa. The Central Emergency Government Headquarters was originally built 'in secret' between the years 1959 and 1961 to keep Canada's 13th Prime Minister John Diefenbaker, the Governor General and 535 others safe in case of a nuclear attack. The four underground levels are approximately 100,000 square feet (480 m2) and offered everything necessary to run the country for 30 days. Even the hospital could take care of every ailment imaginable except for brain or open-heart surgery! Thank goodness it was never used for its original purpose, and after being declared a National Historic Site, ceased operations as a communications centre in 1994.
