A notable feature of Expo 67 was the World Festival of Entertainment, featuring opera, ballet and theatre companies, alongside orchestras, jazz groups, famous Canadian pop musicians and other cultural attractions.
The Expo was one of the most successful World's Fairs and is still regarded fondly by Canadians. Some even consider it to be one of the biggest events of the 20th century. 1967 is often referred to as "the last good year" before economic decline, Quebec sovereigntism (seen as negative from a federalist viewpoint), and political apathy became common. Despite this there were problems: FLQ terrorists were active at the time and death threats were issued. American President Lyndon B. Johnson's visit became a focus of anti-war protesters.
More than 50 million visitors (50,306,648) attended Expo 67 at a time when Canada's population was only 20 million, setting a record for World Fair attendance that still stands. The fair was visited by many of the most notable people of the day including Queen Elizabeth II, Lyndon Johnson, Princess Grace, Jacqueline Kennedy, and Charles de Gaulle, who created an international controversy when he shouted "Vive le Québec libre!" ("Long Live Free Quebec") from the balcony of Montreal city hall on July 24 (this slogan being well known as the rallying cry of the Quebec independentists).
Montreal's former baseball team, the Expos, was named after the event. After 1967, the site struggled on for years as a standing collection of international pavilions known as "Man and His World." However, as attendance declined, the physical condition of the site deteriorated, and less and less of it was open to the public. In 1975 the Île Notre-Dame section of the site was completely rebuilt around the new rowing basin for Montreal's 1976 Summer Olympics. 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. In 1976, a fire destroyed the acrylic outer skin of Buckminster Fuller's dome. With the site falling into disrepair it began to resemble ruins of a futuristic city. In the late 70s, scenes for Robert Altman's post-apocalyptic ice age Quintet (film) were shot on site, as was an episode of Battlestar Galactica, which portrayed it as the ruins of a city left behind after a biological attack. Some of the footage showing the United Kingdom pavilion was reused in Buck Rogers. The remaining original exhibits of the site closed for good in 1982.
Today, the site houses the Montreal Casino (in the former pavilions of France and Quebec), the Circuit Gilles Villeneuve race track, an amusement park called La Ronde, and many acres of parkland and cycle paths on Ile Saint-Helene and the western tip of Ile Notre-Dame. The old US pavilion still stands, currently housing a science museum on the theme of water (the Biosphère). On Ile Notre-Dame the Olympic basin is used by many rowing clubs of the area. In summer, an artificial beach, recently built on the shore of the remaining artificial lake, has been very popular. In previous years the site has been used for a number of events such as an international botanical festival, Les floralies. The young trees and shrubs planted for Expo 67 are now mature. The plants introduced during the botanical events have prospered also. In the warmest weeks of the summer the two islands are cool, leafy havens compared to the overheated city. In the winter, brave Montrealers skate on the frozen Olympic basin of Île Notre-Dame, whipped by the glacial winds coming from the Saint Lawrence River.
The band They Might Be Giants referenced Expo '67 in their song Purple Toupee.
With the closure of Expo 67, the exhibition site on Saint Helen's Island was used during the next and several following years as an attraction called "Man & His World" (which was the sub-title of Expo 67). The Montreal Metro (Underground railway) was opened in time for Expo 67, and included a station on St Helen's island to give public transport to the exhibition. This resulted in Montrealers having easy access to the park on the island after all of the other attractions had closed.
Absent countries included The People's Republic of China, Spain, South Africa, and many countries of South America.
