Parc Jean-Drapeau is comprised of two islands, Saint Helen's Island and the artificial Notre Dame island The islands were the site of the Expo '67 World's Fair. Notre Dame Island was constructed for the exposition, and Saint Helen's Island artificially extended at its north and south ends. Both islands were constructed or extended with the dirt removed during the excavation works for the Montreal metro system. The park was renamed in honour of Jean Drapeau, the late mayor of Montreal and initiator of Expo 67.
The Montreal Fireworks Festival began in 1985. Leading fireworks companies from different countries participate in a spectacular show where during 30 minutes approximately 6,000 fireworks are shot.
