Expo 67 may have opened a half century ago today, but it's 2017 that seems kind of old by comparison.

The art and architectural legacy of Montreal's 1967 International and Universal Exhibition — few, but impressive — litter Canada's landscape like the ruins of a fantastical future to which we somehow, somewhere lost the thread.

Found as far away as Newfoundland, Expo 67's remnants continue to exude some of the weird, wondrous magic of that Summer of Love in Montreal, when anything and everything seemed possible.

Here are a few:

Buckminster Fuller's geodesic dome served as the U.S. Pavilion and encapsulated Expo 67's revolutionary vision of a world made better and more livable through design and technology.

Habitat 67, Montreal

Designed for Expo 67 by McGill-trained architect Moshe Safdie, Habitat 67 is now one of Montreal's more exclusive addresses. Safdie refutes the popular (and not a little ironic) notion that Habitat was conceived as a model for social housing. In 2012, the architect told The Walrus magazine "when we built the building, we didn't say low income, middle income, whatever. We said, 'a new model for urban living.' As a concept, I was not differentiating in my mind the idea of low and middle income as having different needs."

Yugoslavian Pavilion, Grand Bank, Nfld.

The Yugoslavian Pavilion from Expo 67 is now the Provincial Seamen's Museum in Grand Bank, Nfld. The building was purchased for $1 after Expo 67 and its seven triangle-shaped modules are now re-imagined as the "sails of a schooner," according to the the museum's website.

The French Pavilion from Expo 67 is now home to the Montreal Casino. According to the original Expo 67 description of the pavilion, it featured "aluminum sun-breaker strips, providing an attractive sculpture effect" and "a steel arrow." There was also talk of France loaning the Eiffel Tower to Montreal for Expo 67, but that didn't happen.

Czechoslovakian Pavilion, Grand Falls, Nfld.

This postcard shows the Czechoslovakian Pavilion as it was at Expo 67. After the world's fair, the pavilion was gifted to the people of Gander, Nfld., to thank them for their rescue efforts after a Czech airliner crashed on take-off from Gander Airport on Sept. 5, 1967, killing 37 people. Today it's known as Gordon Pinsent Centre for the Arts.
