The 1967 International and Universal Exposition or Expo 67, was a World’s Fair held in Montreal, Quebec from April 27 to October 29, 1967. The Exposition was incredibly popular, with 62 nations participating from around the world. It also set the highest single-day attendance record for a World’s Fair on the third day of the exhibition – 569,500 visitors, out of a total of 54,991,806 who would eventually visit the exhibition. Peter noticed that many travelers on the railways were attending Expo 67 that summer.
