After the closing of Expo in late 1967, the site continued its fair vocation under the name Man and His World until 1984, and finally, most facilities were dismantled and the island was converted into a park.

The islands also boast numerous hiking and skiing trails, bike paths, large athletic grounds and diverse other services and conveniences.

During the more temperate months, a diverse array of free and pay activities are offered on a weekly basis in addition to the aforementioned attractions.

There's also a weekly electronic dance festival located under Alexander Calder's sculpture Man, commissioned for Expo 67.

A considerable portion of Île Notre-Dame was redeveloped into an intricate and elaborate flower garden in the early 1980s, which remains today.

The only other significant remnant of the former World's Fair is the Place des Nations at the western end of Île Sainte-Hélène, though this is abandoned and officially off-limits.
