Big ol' holes in the ground
I think the only thing we have up here which would be comparable would be the "Diefenbunker" (named after the Prime Minister that ordered its construction - Diefenbaker). I think there might have been more than one of these things, designed and built to protect Canada's elite (hockey players, donut chefs, CBC radio hosts) in the event of nuclear holocaust.
It is or was up for sale at some point, but I seem to remember hearing something about the government backing off a bit when it looked like a motorcycle gang was going to come up with the largest offer for it...
