When Canada Outdid Herself: Memories of Expo 67 - When I went to NS on the student exchange we traveled by train and stopped here. We only had 1 morning to spend here so instead of waiting in line to see the pavilions, we backed in the exits with the crowds that were coming out.
Expo 67 was open from April to October, 1967 in Montreal, Canada. The site consisted of two islands and a peninsula in the middle of the St. Lawrence River. The admission ticket was referred to as a passport and entitled the holders to free entry to all pavilions as well as unlimited use of the mass transit system - Expo-Express. The passport could be filled with "visa stamps" at the National Pavilions. Via: http://www.alamedainfo.com/Expo_67_Montreal.htm
