Ada: Jump to the nineteen sixties, and Montreal throws itself a coming-out party. The Metro opens in sixty-six. Then, in sixty-seven, Expo — a world's fair themed 'Man and His World.'
Theo: How big are we talking?
Ada: Around fifty million visits, though the counts differ. Buckminster Fuller's American pavilion is a giant geodesic dome. And a twenty-nine-year-old architect, Moshe Safdie, builds Habitat sixty-seven — houses stacked like concrete boxes tumbling on each other.
Theo: Twenty-nine and he reinvents the apartment block. That's Yev's kind of invention story.
Ada: Then comes the nineteen seventy-six Summer Olympics, and the Olympic Stadium — the Big O. It's where Nadia Comăneci scores the first perfect ten in gymnastics history.
Theo: I sense a but coming.
Ada: The stadium runs so far over budget that the debt isn't paid off until two thousand and six. Locals started calling it the Big Owe.
Theo: Thirty years of bills for one summer. So how do you sum up this whole island?
Ada: With the two things that were always there. Cartier's mountain, and the river he couldn't get past.
Theo: That's the thread, isn't it — the rapids that stopped him are the reason any of it happened.
Ada: Every turn came back to that geography. A barrier made it a portage; the portage made it a fur capital; the peace, the conquests, the canal, the factories, the fair — all pinned to one stubborn stretch of white water.
Theo: What stays with me is how a dead-end became a doorway. Nobody chose Montreal — the river did.
Ada: And if a barrier can build a city, it's worth asking what other obstacles quietly shaped the places we live. If a question like that strikes you mid-episode, you can always stop us and ask.
Theo: There's also a whole story in Safdie's Habitat and its wild idea for how people should live — that's one tap away if you're curious.
Ada: This was Historai — where history answers back.
