===Man and His World (1968–1984)===
After 1967, the exposition struggled for several summer seasons as a standing collection of international pavilions known as "Man and His World".<ref name="Expo Legacy" /> However, as attendance declined, the physical condition of the site deteriorated, and less and less of it was open to the public. After the 1971 season, the entire Notre Dame Island site closed and three years later completely rebuilt around the new [[Rowing at the 1976 Summer Olympics|rowing]] and [[Canoeing at the 1976 Summer Olympics|canoe sprint]] (then [[canoe racing|flatwater canoeing]]) [[Venues of the 1976 Summer Olympics|basin]] for Montreal's [[1976 Summer Olympics]].<ref name="Olympic Basin">{{cite web |title=Olympic Basin |url=http://www.parcjeandrapeau.com/5-Olympic_basin-montreal-attraction.html |publisher=Parc Jean-Drapeau |archive-url=https://web.archive.org/web/20120428042821/http://www.parcjeandrapeau.com/5-Olympic_basin-montreal-attraction.html |archive-date=April 28, 2012 |location=Montreal |date=2012 |url-status=dead}}</ref> Space for the basin, the boathouses, the changing rooms and other buildings was obtained by demolishing many of the former pavilions and cutting in half the area taken by the artificial lake and the canals. By this point, both major transportation systems for the site, the [[Minirail#Notre Dame Island (Blue)|Blue Minirail]] and [[Expo Express]], had permanently ceased operation.

In 1976, a fire destroyed the acrylic outer skin of [[Buckminster Fuller]]'s dome, and the previous year the Ontario pavilion was lost due to a major fire.<ref name="Biosphere">{{cite news |last=Kelly |first=Mark |url=http://www.cbc.ca/archives/categories/society/celebrations/expo-67-montreal-welcomes-the-world/a-pavilion-reborn.html |title=Expo 67's U.S. Pavilion Becomes the Biosphere |work=Prime Time News |date=June 5, 1995 |publisher=[[CBC News]] |access-date=April 26, 2012 |location=Toronto}}</ref> With the site falling into disrepair, and several pavilions left abandoned and vandalized, it began to resemble ruins of a futuristic city.

In 1980, the Notre Dame Island site was reopened (primarily for the [[Floralies Internationales de Montréal|Floralies]]) making both islands simultaneously accessible again, albeit only for a brief time. Minor thematic exhibitions were held at the Atlantic pavilion and Quebec pavilion at this period. After the 1981 season, the Saint Helen's Island site permanently closed,<ref name="Expo Legacy" /> shutting out the majority of attractions. Man and His World was able to continue in a limited fashion with the small number of pavilions left standing on Notre Dame Island. However, the few remaining original exhibits closed permanently in 1984.<ref>{{cite news |first=Georges |last=Lamon |date=August 31, 1984 |title=Terre Des Hommes, C'est Fini! |url=https://scontent-a-iad.xx.fbcdn.net/hphotos-xfa1/l/t31.0-8/1899575_10152698984043968_7099189167940062300_o.jpg |archive-url=https://web.archive.org/web/20150108031953/https://scontent-a-iad.xx.fbcdn.net/hphotos-xfa1/l/t31.0-8/1899575_10152698984043968_7099189167940062300_o.jpg |archive-date=January 8, 2015}}</ref>
